Do I know, whether any load testing tool is there for testing SAP GUI based applications?
I have been using Load Runner as of now, but the license is going to expire soon. So, I am in a position to find the better replacement for the same.
Responses are appreciated :-)
Thanks in advance.
There are no open source tools for testing SAPGUI applications. Architecturally, none of the existing open source applications have hooks to the automation interface used by SAP. So, you may discount the previous answer which concentrates on web-based interfaces or a generic TCP interface. The interface for SAPGUI automation is on the client.
SAPWeb, on the other hand, may be tackled with standard commercial and open source solutions which architecturally support the capture, modification and reproduction of traffic at the HTTP protocol layer.
Renew your LoadRunner license. The cost in hours of labor to modify any of the available open source tools will more than exceed the cost of your LoadRunner license. You will need to establish a relationship with SAP for the interface documentation. You will need to build a recording interface and a playback interface. You can look to the R&D output from the big vendors, HP, Borland, IBM, to see what a non trivial and high engineering dollar challenge this is.

I'm trying to figure out the licensing consequences of using Grails as the base for closed-source non-free software. This would be a server product that is downloaded and installed. Users would not have the right to redistribute it or run it as a hosted service.
Grails and Groovy themselves are cool: they're licensed under ASF 2.0 which is great. However, Grails has a billion dependencies and I'm going crazy tracking them all down.
Grails can generate a list of software that your project depends on by running grails dependency-report. I'm going through that list of dependencies, BUT:
Many of the libraries do not list their licenses. So I'm going to each and every library and figuring out its license.
I'm guessing dependency-report doesn't list all the transitive dependencies (libraries that THOSE libraries include, and so on) because they aren't fully specified in Ivy.
Has anyone gone through this exercise before? Just knowing the end result would be a HUGE help. Actually having a list of all the dependencies and their licenses would be a MASSIVE help.
Thanks!
I spent a day tracking down all the Grails 1.3.7 dependencies. Here's the gist:
Grails itself has the nice friendly ASF license
Some subcomponents use more restrictive licenses
However, none of the subcomponents use what I'd call a "showstopper" license like GPL
However, some people WOULD consider a few of the licenses to be showstoppers, most notably the LGPL used by Hibernate.
Lawyers are scared to death of LGPL because it's easy for developers to make a mistake that forces the entire system to become open source. Things that would trigger this are: modifying any little bit of the LGPL source code, copying any little bit of the source code into your product, or linked to the GPL software "statically" rather than "dynamically" (that's a long discussion).
Because of this, some software companies and purchasing departments have rules forbidding its use.
Here's the subcomponents with more restrictive licensing than ASF. LGPL's the worst:
Hibernate (LGPL)
A bunch of javax stuff (like activation and mail) under CDDL 1.0
org.beanshell BSH is SPL
javassist is MPL
Everything else is licensed BSD, MIT or ASF. Those are fine.
I should think that all of the Grails dependencies will be fine for use with commercial software since SpringSource sells commercial support for it. You could try asking them about licensing issues as they probably have it all figured out.
Can I use Grails in proprietary software?
Ask Oracle, Grails is running on Java. It might be restricted through higher rights so you might need to get a license from Oracle first to create your specific software with it. Better ask the vendor of the platform first.
[...] Java specifications are proprietary technology that must be licensed directly from the spec lead under whatever terms the spec lead chooses.
See Apache foundation resigns from Java community
Next to that it depends on the license of the Grails package. It's released under ASF 2.0 as you write. I would furthermost assume that this license applies to the whole package as the website suggest, but you must check the whole source code on your own if you really want to rely on this, because the software comes with no warranty. In case the Grails folks made a mistake in licensing it falls back to you in a larger share if the information they provided was wrong.
Keep in mind that you are asking about creating your own proprietary software. That's a job on it's own, your business, and you need to take care for anything legal then on your very own.
You can never rely to any comment unless it's one of a lawyer that is acting behalf of yourself for real.
There is one plugin that might be helpful to check upfront visible licensing terms: http://www.grails.org/License+Plugin
The ASF 2.0 license is a free software license, so even if you consider it "friendly" with all the attitude you show, keep in mind that it has termination clauses as well as the GPL / LGPL. Those are to protect the freedom of the software.
The license at the Grails web site will surely have an answer.
I have a co-worker with a strong background in Ruby that is interested in getting started with Delphi and native development. However, I understand that Turbo Delphi (based on Delphi 2006) is no longer available for download.
So...where does that leave him? Is there any low cost or introductory version of Delphi available legally somewhere? Or is there an offering on the horizon from Embarcadero?
Note: Please don't suggest any legally questionable versions, as that is not an option we will consider.
UPDATED: To sum up all answers the only legal and free version of Delphi that you can download and install now (unless you already have a personal license for Delphi 7 Personal or Turbo Delphi) is Delphi Community Edition.
And the next closest thing is the Lazarus IDE and the Free-Pascal compiler.
This with this should be close enough. It speaks the language at least.
IMO the Delphi 7 Personal Download is the only available legal "non-expensive" version of Delphi. But is is really limited in its features.
It's really a shame that Embarcadero forces one to invest some USD 900+ even if one wouldn't need all the bells and whistles of the Pro version. Especially if products from the "other company" (the Express versions) are given away for free.
I am talking about the need for the discontinued Turbo product line (based on a stable foundation, i.e. D2010 and not D2006) for the hobby software developer to get him started. Maybe his is even willing to upgrade to a full featured version some day.

Extracts from "About Lazarus":
So just what is Lazarus?
Lazarus is the class libraries for Free Pascal that emulate Delphi. Free Pascal is a GPL'ed compiler that runs on Linux, Win32, OS/2, 68K and more. Free Pascal is designed to be able to understand and compile Delphi syntax, which is of course OOP. Lazarus is the part of the missing puzzle that will allow you to develop Delphi like programs in all of the above platforms. Unlike Java which strives to be a write once run anywhere, Lazarus and Free Pascal strives for write once compile anywhere. Since the exact same compiler is available on all of the above platforms it means you don't need to do any recoding to produce identical products for different platforms.
Yeah, but what about the GUI? What widget set are you using?
That is the neat part. You decide. Lazarus is being developed to be totally and completely API independent. Once you write your code you just link it against the API widget set of your choice. If you want to use GTK+, great! If you want it to be Gnome compliant, great! As long as the interface code for the widget set you want to use is available you can link to it. If it isn't available, well you can write it.
For example. Let's say you are creating a product on Windows using the standard Windows widgets. Now you want to create a Linux version. First you decide what widget set you want to use. Let's assume you want to use gtk+. So you copy the code over to your Linux development machine, compile, and link against the gtk+ interface unit. That's it. You've now just created a Linux version of the Windows product without any additional coding.
At this point in the development we are using Win32, gtk+, Carbon and QT as our API widget set. As soon as Lazarus reaches a 1.0 release developers will be able to start to create the interface unit to tie the LCL (Lazarus Component Libraries) to other widget sets.
So is this thing really RAD like Delphi?
It sure is. Is it totally completed? No not yet.The over all IDE is complete and can be used for most programming needs. Several aspects
of the project are still in need of help. Hint. Hint.
Can I use my existing Delphi code?
Some of it yes. If the code is standard Delphi pascal and it uses the standard components found in Delphi then the answer is yes. If it uses some specific database, OCX, or DCU then the answer would be no. These items are specific to Windows and would only work on and within Windows. However, if you are only looking to create a Windows product using Free Pascal and Lazarus then the answer would be yes. This hasn't been added to the LCL yet but it should be possible in the future.
Can I create commercial products with this?
Yes. The code for the Free Pascal compiler is licensed under the GPL. This means that it is open source, free, whatever name you want to stick to it. You can modify the code if you wish but you MUST distribute those changes or make them available to others if they wish to use it.
The FCL (Free Pascal Component Libraries) and the LCL (which will eventually become part of the FCL) are licensed under a modified LGPL. In a nut shell this means that you can write your own proprietary software that just links to these libraries. You can sell your application without the need to supply or make available your code. However, as with the compiler if you make modifications to the FCL or LCL you must make those changes available to the general public and the world.
Just for completeness, you can get a 30 day trial: https://downloads.embarcadero.com/free/delphi
Also, I'd suggest going to a Delphi conference. You have about a 1 in 30 chance of winning a free copy or a significant discount.
Embarcadero launched a starter edition of Delphi for $199. Latest version is Delphi 10 Seattle.
As Mohammed pointed out there is a upgrade price of $150, from any other IDE or developer tool product including earlier Delphi products.
Important update:
Don't simply download any Delphi version from a mirror, even when they used to be free, when they are no longer available from Borland/CodeGear/Embarcadero.
According to Alexander's comment and contrary to the quote below, even though they were free, it may not be legal to newly install them now.
I wasn't aware of that when I quoted the answer from the question mentioned. Sorry.
if you however decide to learn Delphi,
you might want to look for Delphi 7
Personal which was removed from
Borland / CodeGear / Embarcadero
websites, but still is available on
some mirror hosters. I believe it is
legal to use this as it was once
published as freeware. – migajek

Quoted from a comment on the question Do I need to free these objects?
The same may apply to Turbo Delphi 2006...
Since July of 2018 there is a Free Community Edition of Delphi.
At the moment the Delphi Community Edition supports both VCL and FireMonkey as well as building for Windows, macOS, iOS and Android, and is a feature rich IDE (compared to Turbo Delphi) with a limited license. In terms of features the new Community Edition is much, much, much better than past Starter or Turbo editions.
It's targeted at individual developers or companies with total revenue less than 5000 USD and less than 5 developers in the organization (eg. freelance developers, startups, students, non-profits). Note that the total revenue threshold includes all your projects and contracts, no matter if the Community Edition was used in those projects or not.
The Delphi Community Edition comes with a 1 year license. Once it expires you have to reinstall the Community Edition and accept the new Community license (license terms might have changed by then). In this regard the Community Edition differs from Turbo Delphi, which was kind of "use forever" once installed with a personal license.
As another side note, the Community license does not allow transfering the command line compiler to other machines.
Some quotes from the Delphi Community Edition FAQ:
Community Edition is
both designed to allow individuals and startups to bootstrap their
vision until annual revenues reach $5,000 at which point a
Professional Edition license can be purchased.
If you're an individual you may use Community Edition to create apps
for your own use and apps that you can sell until your revenues reach
$5,000 per year.
If you're a small company or organization without revenue (or up to
$5,000 per year in revenue), you can also use the Community Edition.
Once your company's total revenue reaches US $5,000 per year, or your
team expands to more than 5 developers, you can move up to an
unrestricted commercial license with Professional Edition.
...
You may sell any apps or components developed with the Community Edition under the Community Edition license until your annual revenue exceeds US $5,000 or local currency equivalent. Please see license terms here.
...
Can I sell my apps or components built with the Community Edition?
A Professional, Enterprise or Architect edition license is required for developing or deploying any apps or components within any company with total company revenues exceeding US $5,000 or local currency equivalent.
...
If I work for a company with more than US $5,000 in revenue, can I still download Delphi Community Edition or C++Builder Community Edition for my own personal use?
You can download Delphi Community Edition or C++Builder Community Edition as an individual and use it to develop applications for your personal use and use it to create software for you to sell (up to US $5,000 in revenue, see License Agreement for details).
...
How can I get a new 1 year key after my current CE key expires?
Users will be able to request a new 1 year key through the website. That key will be > applicable to the current CE edition that’s available for download at that time.
We will assist you to stay current and up to date, always on the latest version.
As Marco Cantu said Long live to Delphi!
You might alternatively take a look at free CodeTyphon. It is a powerful one click installation package for cross platform native Delphi like RAD/IDE based on Lazarus/FreePascal. Your friend will start coding just few minutes after download. CodeTyphon already supports 4 CPU/OS hosts (Win32, Win64, Linux32, Linux64), and 16 CPU/OS targets (arm-Wince, arm-Linux, arm-Embedded, arm-gba, arm-nds, i386-Win32, i386-Linux, i386-FreeBSD, i386-Haiku, x86_64-Win64, x86_64-Linux, x86_64-FreeBSD, powerpc-Linux, powerpc64-Linux, sparc-Linux, sparc-Solaris). More are supported in Lazarus/FreePascal, but others are not yet integrated in CodeTyphon.

I am looking a tool for protect and licensing my commercial software, Ideally must provide an SDK compatible with Delphi 7-2010, support AES encryption, Keys generator and capacity to create trial editions of my application.
I am currently evaluating ICE License. Someone has experience with this software?
Here's my list of software protection solutions. I'm looking at switching from ASProtect to another protection so I'm also in the process of analyzing most of these programs:
Themida (Oreans)
http://www.oreans.com/products.php
There are unpacking tutorials for all the versions of Themida. There is however the possibility of requesting "custom" builds which might help avoid this.
Code Virtualizer (Oreans)
http://www.oreans.com/products.php
Allows to protect specific parts of the application with a Virtual Machine. A cracker on a forum said he "made a CodeUnvirtualizer to fully convert Virtual Opcodes to Assembler Language".
EXECryptor
Very difficult to unpack. GUI does not work under Vista. Appears to no longer be developed.
ASProtect
Small protection overhead. Appears to no longer be developed.
TTProtect - $179 / $259
13 MB download. Chinese developer. Adds about xxx overhead to the exe.
http://www.ttprotect.com/en/index.htm
VMProtect - $159 / $319 (now $199/$399)
http://www.vmprotect.ru/
10 MB download. Russian developer. Seems to be updated frequently. Supports 32 and 64-bit. Uncrackable according with one exetools post, but there seems to be an unpacking tutorial already.
Enigma Protect - $149
http://enigmaprotector.com/en/home.html
7 MB download. Russian developer. Regarded as very difficult to crack. Adds about xxx overhead to the exe.
NoobyProtect - $289
http://www.safengine.com/
10.5 MB download. Chinese developer. Regarded as very difficult to crack. Adds about 1.5 MB overhead to the exe.
ZProtect - $179
http://www.peguard.com
RLPack
http://www.reversinglabs.com/products/RLPack.php
KeyGen already available.
One thing to note is that the more protection options you enable on the software protector, the bigger the possibility of the protected file being flagged by an anti-virus as a false-positive. For example, on Themida, checking the option to encrypt the file, will most likely create a few false-positives by a few anti-virus programs.
I'll update this answer once I get more replies from a hackers forum where I asked some questions about these tools.
And finally, don't use the build-in serial number/license management of these tools. Although they might be more secure than using your own, you will be tied up to that specific tool. If you decide to change software protection in the future, you will also have to manage all the customer keys transfer to a new system.
Don't bother. It's not worth the hassle. Only a perfect licensing system would actually do you any good, and there's no such thing. And in the age of the Internet, if your system isn't perfect, all it takes is for one person anywhere in the world to produce a crack and upload it somewhere, and anyone who wants a free copy of your program can get it. (And using a pre-existing library just gives them a head start on cracking it.)
If you want people to pay for your software instead of just downloading it, the one and only way to do so is to make your software good enough that people are willing to pay money for it. Anyone who tells you otherwise is lying.
I have used OnGuard (using the Delphi 2009/2010 source from SongBeamer) along with Lockbox to handle encryption with success. Both are commercial quality libraries and are free to use with full source.
I did once also use IceLicense, but switched to OnGuard/Lockbox which allowed me greater control over the key generation process which we embedded directly into our CRM system.
Of course there is no %100 bullet-proof protection suite, but having some type of protection is better than having nothing.
I worked with WinLicense in Delphi 2009 and Delphi 2010 on Windows XP and Vista. It is a good product with lots of protection options, and customizations. It provides a SDK for developers, and has nice documentation and samples. It also provides a license manager for you. They provide trial download too.
As far as I remember, they offer some customer specific versions too; that means they are willing to provide a custom-built product which is customized according to your needs, but of course that will cost more.
Since WinLicense is a well-known and popular protection suit, many crackers are after it. As you know, the more famous a tool is, the more appealing it is to crackers. But the good thing about Oreans is that they actively monitor underground forums, and provide frequent updates to their products.
So IMHO, if you are supposed to buy a prebuilt protection suite, then you'd better go for WinLicense.
A little late to the post, but check out Marx Software Security (http://www.cryptotech.com) they have a USB device with RSA & AES on chip, with network based license management.
I bought a license for ICE License in 2007. Unfortunatly (as far as I know) the component haven't been updated since June 2007. Back then a Vista compatible version was in the work but never came out of beta. I don't think they updated the component for Delphi 2009 and 2010 yet.
Ionworx is an one man company which might explain the lack of updates and lack of answer to support questions (emailed them 2-3 times since 2007 and never got back to me). They also removed their support forum from their site.
ICE License is better than nothing but I would stay away from this product because the lack of updates & support.
I investigated this a few years ago, and came to the following conclusions:
All copy protection can be broken
Nag screens on load irritate people to the point where they may stop using the product
Random nag screens can interrupt the users work flow to the point where they perceive it to be a reduction in the speed of the application
Set up compiler options, so that you have a version as a demo (perhaps with save functions removed), reduce multi user versions so that only one client can connect at a time (not using, for ex:
if connection=1 then reject
but reducing the viability for multiple connections in code)
Themida has good protection, and I think it built with Delphi too ;-)
if you have a better budget, you can look at winLicense and other tools from same company.
Have a look at this question which is pretty similar, and includes many of the tools.
Take a look at InstallShield. We've been using it for a while ourselves, and it has a lot of capabilities for trial support, licensing, and others. I don't know about key generation off the top of my head as our use doesn't require keys, but there's a lot available to you from them.
AppProtect wraps an EXE or APP file with computer unique password or Serial Number based online activation. QuickLicense is a more comprehensive tool that support all license types (trial, product, subscription, floating, etc.) and support both a wrapping approach or API to apply the license to any kind of software. Both are available from Excel Software at www.excelsoftware.com.

I'm currently developing a web app on Django/Python, and I consider moving to ASP.NET MVC. I downloaded the Visual Web Developer Express edition, read NerdDinner, and I'm ready to go. I will probably keep working on MySQL.
One of the reasons I chose Django+MySQL in the first place was that it was free of charge. I'm bootstrapping a business and can't afford to pay for expensive software, even for deployment (storage and bandwidth are the exception).
My question is: can I develop on the express edition and get my product to production without having to pay to Microsoft? This is both a legal question and a practicality question (Assume I'll use open source version control, build server, etc).
I'm not experienced in Microsoft's different licenses, I wondered if anyone has any experience in driving a product to the web based solely on the express editions (I know you guys are not lawyers, but some of you are probably working at companies paying lawyers to help with such decisions...)
You've asked two questions here, so let's take a look at both.
From a legal standpoint the answer is pretty straightforward: yes, Visual Web Developer Express is provided free of charge and there is no limitation regarding using it commercially.
Your second question has to do with the practicality of using Express editions commercially. The short answer is: yes. The longer version of the answer sounds a little more like "yes, but...".
Although Visual Studio Express editions are fantastic -- especially when you consider their price -- you should be aware that they do lack functionality. To me, the most important things Express editions lack are --
Extension support. There's a healthy Visual Studio add-in ecosystem out there that you'll be locked out of. Not a fatal flaw, for sure. Just something to keep in mind.
Ability to create setup projects. Again, not fatal. You can do it manually or using some external solution. Also, if you are developing something for use on one customer (or for yourself) this is a complete non-issue.
Native 64-bit support. This is the one I can't work around. If you need to work on 64-bit environments and use some 64-bits controls, you're in a pickle.
Support for test projects. If you are into test-driven development, this is a very cool feature you'll miss on the Express editions.
Also, they have no class designer, some (small) limitations on debugging and most development tools you'll find that work with Visual Studio won't work with the Express editions.
All in all, you can definitely develop with VS Express. Compared to the tools you probably had for Django+Python, Visual Studio Express is a big leap forward anyway IMHO.
Also, you can always go with the Express edition for now and upgrade later if necessary.
Point 7 in the "Express" FAQ probably answers it best:
Can I use Express Editions for commercial use?
Yes, there are no licensing restrictions for applications built using Visual Studio Express Editions.
Other then that, reading the EULA should confirm that there is no "products built with this software is for private use only" clauses.
Not only can you develop ASP.NET MVC for free, you can do it on Linux using Mono, as Miguel points out and Michael explains... so in addition to no license fees for the runtime or IDE, you can host on free operating systems too!
You can also use MonoDevelop on Mac OS-X and although I'm pretty sure Windows users will prefer Visual Web Developer Express, they are getting MonoDevelop running on Windows, too.
When you've made your first million dollars, then you can 'upgrade' to Visual Studio 2010 :)
Yes, the Express editions are really free.
yes, you can develop on the free versions of microsoft software. you will have to pay for the os license of the development and hosting servers though.
for a business you may want to investigate the bizspark program which can give you up to three years of everything, including hosting.
It is absolutely possible to develop and deploy ASP.NET and ASP.NET MVC applications without having to pay to Microsoft. I see no any limitations/differences (both legal and practical) in deployment of ASP.NET applications, developed in express/full versions of VS. Personally I would recommend to buy VS2008 Pro (or maybe wait for VS2010) - it's much more powerful then VWD Express. Yes, It is expensive but I think it is worth its money.
UPDATED:
Reliable Dedicated/VPS hosting is expensive for both Linux/Windows platforms. So if your site will grow quickly - yor main costs will be hosting not tools
in development yes it is free visual studio express is really free but when it comes to deployment you will really need Windows server 2003 or 2008 you might also need another edition of SQL server if express doesn't meet the requirement :)
There is no need to settle for the Express editions or open source. If you are a legitimate startup, you can join Microsoft's relatively new BizSpark program and get a free MSDN subscription, which includes full editions of all the software for development purposes (e.g. Windows Server, SQL Server, etc).
Plus for web apps you get licenses to deploy the software in production, which I think makes BizSpark unique versus other MS partner programs. It doesn't include free hosting however.
Check out the site for eligibility requirements and restrictions.
(sorry Matt I know you mentioned Bizspark, but I wanted to provide more info and emphasize how relevant this is for the question).
