Does Struts2 work on RAD 7.5.5 ?
I am creating a sample dynamic web project in RAD, and my JSP pages are getting called, but the Action classes are not invoked.
I am getting the below error:
Error 404: SRVE0190E: File not found: /hello
It supports Struts2, as every other 3rd party technology, but it does not provide any specific tooling as for Struts 1.3.
Rational Application Developer 7.5 and 8.0 do not provide any specific
tooling for Struts 2.x (such as it does for Struts 1.x).
For example, you will need to obtain the Struts 2.x runtime files from
the Struts Web site yourself and manually add them to (and configure
them within) a Dynamic Web project in which you intend to use Struts
2.x.
Note: A Struts 2.x application is treated as a standard Dynamic Web
project.

You can verify your installation with the Introduction to Struts 2.x using RAD 7.5 guide (that has nothing to do with S2, despite the title),
and download and run a template project from here , to start from something running.
By the way your seems an configuration error, check your cfg from zero, or use the template.

I'm using Visual Studio 2012 and have just installed "Microsoft ASP.NET and Web Frameworks 2013.1 - Visual Studio".
As expected, it added the option to create an "ASP.NET MVC 5 Empty Project". The thing is, I see no way of jump-starting an already functional "base application" as I had when I was using MVC 4 (e.g. "Asp.NET MVC 4 Web Application"). I only see an empty template.
I've seen answers such as:
How can I add the MVC 5 project template to VS 2012?
Create and Run MVC 5 Project in VS 2012
Direct download link to ASP.NET MVC 5 for VS 2012
And found this article on the matter.
This is obviously not a show-stopper as I can always create the application from a scratch, but I still would like to know if it is possible to achieve that on VS 2012. Did I miss a step, or do I need VS 2013 for that? A fully functional Web application template (with authentication etc.) would be nice to dabble around MVC 5's new features or for prototyping.
After creating a new project using ASP.NET MVC 5 Empty Project, you can right click on the project, then click Add.. > New Scaffolded Item..., select MVC on the left, then MVC 5 Dependencies and choose Full dependencies from the prompt.
This will add a default layout (Views\Shared\_Layout.cshtml), Content folder, Scripts folder with bootstrap, jquery, modernizr, etc, and other things the Web Application template creates.
If you get the error "CS0103: The name 'Styles' does not exist in the current context" just add <add namespace="System.Web.Optimization"/> under <namespaces> in Views/web.config
The answer from Sean Lynch is nice but not really complete.
However there is this nice guy that took the time to prepare the template just like in Visual Studio 2013. You will get everything down to the bootstrap template and pre-configured database table for authentication.
All you need to do is change the DefaultConnection in Web.Config to you SQL Server and voila all the relevant authentication table will be created for you.

Update
The original blog is no longer online, but thankfully his template is still online. You can download the MVC5 Template for Visual Studio 2012 Here:
Direct link to MVC5 Template For Visual Studio 2012
And here is the excerpt from the original blog:
Installing the template is very simple, there are just two steps:
Copy it into the following folder of your computer (creating the directory structure if necessary):
%USERPROFILE%\Documents\Visual Studio 2012\Templates\ProjectTemplates\Visual C#\Web
Once you’ve done this, simply restart Visual Studio and you will have this template available in the dialog box to create a new project under “Visual C# > Web”.
Now you can create applications with a little more shape than the mere empty structure provided by default and enjoy the benefits of adopting Bootstrap and its responsive design, a full membership system and user authentication, bundles, filters, some content pages, etc.
You have 2 option to fix it.
Install the latest 2013 version which have MVC5 support inbuilt (VS2013 missing MVC3 and ASPX file template (ASPX templates will be added in future))
stay with 2012 update 4. Read my old article to get it fixed http://geekswithblogs.net/anirugu/archive/2013/11/28/mvc-5-in-visual-studio-2012-update-4.-how-to.aspx
I'm not using 2012 now, but rather 2013, and I see the mvc 5 template there. However, I did this a while back before I had any mvc 5 templates showing up by installing mvc 5 first. You should be able to download from http://www.asp.net/mvc/mvc5.
Also make sure your target framework is set correctly.
Then I updated the web config like this:
You have to have the correct versions of the assemblies. I googled a lot to get this info, so it should still be available if you do some research.
I have a JSF 2.0 application. Can we use acegi-jsf of version 1.1.3. Can we use this tag library for JSF 2.0.
Acegi does not exist anymore. It was taken over by Spring in April 2008 and continued under the brand "Spring Security". That Acegi tag library is likely JSP targeted and not Facelets targeted. JSF 2.0 was namely introduced in December 2009, which is a long time after the Acegi takeover by Spring.
You should be looking for Spring Security JSF 2.0 tag library instead. However, a "JSF 2.0 tag library" can better be rephrased to "Facelets tag library" in order to end up with a more correct term and thus get better Google hits. You ultimately want to use this on Facelets (XHTML) files, right?
I don't do Spring, but Googling on "Spring Security Facelets tag library" yields among others this link which describes how to manually declare Facelets tag libraries and EL functions. There does thus not seem to be a full integration (i.e. just dropping JAR in webapp without the need to manually create .taglib.xml files), they seem to be working on that for future releases.
We are in the middle of development for a core ASP.NET MVC web project and a customer plugin in the form of an MvcContrib plugin web project -- a web project injected into the core web as an area. The plugin is a soft reference in the core project, so it can be developed completely separately and dropped in.
I am trying to generate a way to debug/code the plugin, so that the multiple custom plugins can be developed independent of the core web.
The developers should only have to worry about coding and testing the plugin code. Also, I don't want them to change the core code in this custom plugin project -- that should be done in the core anyway.
I created the core web as a NuGet package and included all the necessary files so I could include it in a web.
My thinking was that I could create an empty web, install my core web, and the developers could have an F5-driven debugging environment.
I tested by creating a blank Mvc project, installed my core package and included one of my plugins. I changed the namespace of this empty web app to the namespace of the core web, thinking that Visual Studio debugging would properly attach and my core assembly.
Simple VS debugging in the empty app does not work -- I receive an HTTP Exception, most likely due to my routes not being registered. I also see that my log4net is not creating its logs folder, so I know the assembly's app start is not being called.
So I see that VS is not attaching to and calling my core assembly.
Can I use this empty web as a host project for my nuget installed web and debug? If so, what configuration am I missing?
If not, how can I include the core web in each customer plugin project in such a way that I can drop my DLL into the bin and debug it?
Using:
Visual Studio 2010
ASP.NET MVC2
The way we are doing things that works pretty well is to use a combination of Web Activator and Razor Generator (available as a Visual Studio extension). In order to access the views within the core web application, the consuming client application needs to know about them, either because they are all included as file references inside the Nuget package (messy) or because they are compiled into the core web dll. You can do that using Razor Generator. Once installed via Nuget you would need to change the Custom Tool property for each .cshtml file to RazorGenerator, which will create a .generated.cs file for each view. This will allow your sample client to use the layout and views from the core web application.
David Ebbo has some useful blog posts on Razor Generator
Couple that with Web Activator to create a PostActivationStartMethod that runs your initialisation code (such as initialising Log4Net) and you should be good to go. We've had this running in 2 scenarios - consuming the framework package via Nuget and adding a project reference directly. Debugging was not working for the Nuget package consuming route but we don't include the pdb files in the Nuget package. We can debug when adding a project reference directly though.
We have an MVC1.0 application that is compiled against and runs with .Net Framework 3.5.
The application was scanned for security and the scanning organisation reported
Microsoft ASP.NET ValidateRequest Filters Bypass Cross-Site Scripting
Vulnerability
https://community.qualys.com/docs/DOC-3495
What versions of Microsoft ASP.NET are vulnerable? Microsoft has
confirmed that ASP.NET versions 1 and 2 are both vulnerable.
Additionally, Qualys has confirmed that ASP.NET version 3 is also
vulnerable, as it includes the vulnerable component from version 2 by
default. We have tested this in our Labs and confirmed the exploit
works on a fully patched version 3.
We are already upgrading our application to MVC3, but that takes some more time to finish.
Is there any chance I can run and compile a MVC1.0 application against .NET 4.0?
This may arise compatibility issues, Even though there are very few dependencies over the .net framework.
You can refer the following posts.
Is ASP.NET MVC 1 forwards compatible with ASP.NET MVC 2?
ASP.Net MVC 1.0 in Visual Studio 2010
From what I understand, anything that runs on .NET 3.5 should function and complile just fine in .NET 4.0, with perhaps some warnings about depreciated functions, but they will still work.
In case you are still curious/not comfortable, there are some tools available to help verify dependencies and other items such at NDepend
Best recommendation... try it! I can't think of any other reason than what Tommy mentioned about deprecated functions. Also, you can update most of your references with
Update-Package
without arguments.
If it compiles fine, do a quick test run over the views. If nothing seems broken, then it probably isn't.
This concerns the state of Struts2 framework tooling, although currently I use no IDE plug-in, preferring to create projects with maven from scratch. At one time I did use the Netbeans Struts2 plugin but stopped when support lapsed for a time between IDE releases.
It is important to know the state of current tooling and so ask:
What features are offered by the Struts2 IDE framework plugin for your IDE(s)?
Are there any design issues with the plugin? (flaws such as wanting to include old or outdated libraries)
This answer applies to the the Netbeans plugin found here: http://plugins.netbeans.org/plugin/39218 (at time of writing the last updated was : 2011-12-17)
Features
When Starting a new project. File > New Project > Web Application
You now have the option of adding struts2 support, which can product a struts2 demo project.
Not tested, but should assist in validation.xml files.
Issues and Limitations
There is no support to create sources in a Maven Web application.
If you use annotations for validation the plug-in does not help.
There is no more support in struts.xml than provided by the IDE naturally. I would have really liked to see property suggestions at the very least, and it would have been very nice to see a list of name values when in a struts.xml constant tag. The IDE does do auto completion in applicationContext.xml where it expects a class, this would be really helpful in struts.xml for the class attribute of the action tag (among other places).
There is an annoying issue of the plug-in creating struts.xml files with a special icon but when creating new xml documents this icon does not apply (should be applied on the basis of the dtd) so you need to copy and paste the file to get the icon and then change the contents.
It only provides struts2 version 2.0.14 or 2.2.3
Over all I do not recommend this plug-in over a standard Maven Project and manually adding the dependencies.
