I have been able to build rabbitmq server on ubuntu linux. It came already prepackaged and on making, it is able to start as a service. When i got the client source, i failed to make because it appeared like it needed a folder called ./deps/rabbitmq-server. Analysing the code, i find that the author of the client was accessing the same header files as are found in the server, using include_lib("path to rabbit.hrl e.t.c") in his header file called "amqp_client.hrl". I then decided to add rabbitmq_server in the lib dir of erlang so as its paths are automatically added on start up of the vm. But still this didnot help. There is also another folder which the client references called "rabbit_common" for an include folder he assumes would contain all the .hrl files there. Please assist me in building both the client and server on my ubuntu server, for testing.
Also, if anyone has used RabbitMQ server for IMs, please provide some benchmarks and/or your findings on its throughput, speed and number of users. How can it be compared to ejabberd?. How can one create AJAX/Jquery/Javascript clients for Web functionality?
thanks
I hope you had made some progress as far as RabbitMQ and ejabberd are concerned.
Below is a link to an interesting discussion that might be of help.

I recently began looking into WebDAV, as I found it to be an option for letting me play a Blu-ray folder remotely - i.e. without requiring the viewer to download the whole 24gb ISO first.
Add a WebDAV source in Kodi v18 to a Blu-ray folder - and it actually plays! Very awesome.
The server can also be mounted on Windows with
net use m: http://example.com/webdavfolder/
or in Linux with
sudo mount -t davfs http://example.com/webdavfolder/ /mnt/mywebdav
-and should then (in theory) play with any software media players that supports Blu-ray Disc Java (BD-J), such as PowerDVD and VLC.
vlc bluray:///mnt/mywebdav --bluray-menu
PowerDVD.exe AUTOPLAY BD m:
(Unless of course time-out values has been set too low, which seems to be the case for VLC at the moment).
Anyway, all this is great, except I can't figure out how to make my WebDAV server read-only. Currently anyone can delete files as they wish, and that's of course not optimal.
So far I've only experimented with SabreDAV, because afaik that's the only option I have if I want to keep using my existing webhost. Trying with very minimal setups, because I've read that minimal setups should default to a read-only solution. It just doesn't seem to happen.
I initially used the setup from http://sabre.io/dav/gettingstarted/ and tried removing some lines. Also tried calling chmod 0444 MainFolder -R on the webserver. And I can see that everything does get a read-only attribute. But it changes nothing. It's still possible to delete whatever I want. :-(
What am I missing?
Maybe I'm using the wrong technology for what I want to do? Is there some other/better way of offering a Blu-ray folder for remote viewing? (One that includes the whole experience - i.e. full Java menus etc).
I should probably mention that all of this is of course perfectly legal. It is my own Blu-ray project - not copyright material.
Also: Difficult to decide if this belongs on StackOverflow or SuperUser. I ended up posting it on StackOverflow because SabreDAV is about coding, and because there's no sabredav tag on SuperUser.
You have two options:
Create your own file/directory classes for sabre/dav that simply throw an error when trying to delete. You can basically start with a copy of Sabre\DAV\FS\Directory and Sabre\DAV\FS\File and change the methods that do writing.
Since you're considering just using linux file permissions, really the key thing you are missing is that that 'deleting' is not controlled on the file or directory you're trying to delete. To delete a file or directory in unix, all you need is write permissions on the parent directory. However, I wouldn't recommend going this route as doing this will just cause a weird error in sabre/dav, which might leave clients in a confused state. It would result in a 500 error, not the expected 403 error.
I have a project in my localhost, already running, after modifying the php.ini of my XAMPP server [running on Windows 7] (adding: extension=php-intl.dll).
But when i upload this project to my GoDaddy hosting, it doesn´t works and get the following error:
Fatal error: Class 'Locale' not found in /home/content/41/9674641/html/library/zend.2.0.4/Zend/I18n/Translator/Translator.php on line 228
GoDaddy hosting details:
Php version 5.3
Operating system: Linux
i386-redhat-linux-gnu
Zend Framework details:
Zend Library: 2.0.4
I´ve tried what they say on the following links:
http://support.godaddy.com/help/article/1085/can-i-add-a-php-initialization-file-to-my-hosting-account?locale=en
http://support.godaddy.com/help/article/5647/why-isnt-my-phpini-file-taking-effect?locale=en&ci=46061
Also, i´ve called to 24/7 goDaddy support and they suggested me to create a php5.ini file in the root directory, then, they told me to stop all web services (Cpanel/Stats & Monitors/System Processes/end web), but they didn´t told me what do i need to include in the php5.ini file.
I was reading some links and, as my localhost is a windows one, adding the extension=php-intl.dll to the php.ini file worked. So i´ve tried to include in my godaddy linux server: extension=php-intl.so but doesn´t works (neither extension=php-intl.dll).
The problem with the goDaddy hosting began when i started using ZF2 FORMs.
Updates:
1) I´ve got access to the php5.ini of the goDaddy server (i have made a copy on the root of my hosting) using PUTTY: cp /web/conf/php5.ini /var/chroot/home/content/41/9674641/html
Then i have read it and i could not find the "intl" extension, instead of this, i only could find:

2) goDaddy response to my formal support request (ticket):
Thank you for contacting Online Support
I understand you are wanting to get Internationalization extension on
to your hosting account. At this time these are not supported in our
systems at this time. We are going to review this with our developers
to more information. You may receive an email us down the road with
addition information about this.
Please let us know if we can assist you in any other way.
Now i'm thinking that i have two problems:
A) Include the line to enable the extension (i don't know how):
Maybe could be:
extension_dir=/var/chroot/home/content/41/9674641/html/library/extensions/php-intl/usr/lib64/php/modules
extension="intl.so"
B) Include the extension in some location inside my hosting (but i don´t know how):
Maybe i could put the extension files inside: /var/chroot/home/content/41/9674641/html/library/extensions/php-intl
Also, i don't know where to acquire the extension files
C) Is there any known update on ZF2 (skeleton, library ..) that solve this issue ?
Please, i need help as soon as possible.
You can manage PHP modules by using the "Change PHP version" feature of the cPanel interface. Select any version other than "native" and a list of checkboxes will appear.
http://support.godaddy.com/help/article/3937/viewing-or-changing-your-php-language-version?pc_split_value=2
Of course, their support might not immediately mention this solution, which should have been in their knowledge base in the first place.
So I just finished the railstutorial.org twitter clone example and I want to put it online with my web hosting provider bluehost. Right now all I have is a file called sample_app with all of the rails stuff in it. And it works fine when I visit it on localhost:3000.
So I go to my bluehost file manager and there are 9 different folders, like public_html, public_ftp, rails_apps, www, tmp, access_logs, ect. Ive uploaded sample_app into this overall directory and into the public_html directory itself. But when I visit my website it just displays the html in a default.html file in the public_html directory.
What exactly is telling my hosting service to use public_html/default.html of any of the hundereds of different files and folders that are in other places on my server space? How do I find this thing and tell it to instead use sample_app or public_html/sample_app and then process everything in that to display my rails application?
Ive tried using bluehost support and they emailed me and said this would be accomplished by creating a symlink which links ~/rails_apps/NinetyNine/public to ~/public_html. I have no idea how to do this and the guides I find online all tell me to enter a series of commands. I dont know whether to do this in a terminal on my ubuntu system or some command prompt that bluehost provides. If it is at a terminal on my system which directory should I be in? any attempts I have made on my system have resulted in a no such file or directory error. When I asked bluehost to explain this they said that this was outside of the scope of their support and had to do with web development not hosting. It struck me as odd that they were unwilling to explain their own response to my problem but whatever.
If anyone of you could help me or point me in the right direction I would very much appreciate it. Thank you
What is telling my hosting service to use public_html/default.html ?
That would be a setting the web server configuration, probably Apache.
In Apache's case, the public_html directory is usually enabled with the
UserDir directive.
The default.html, is also an Apache configuration, DirectoryIndex.
Answering these because you asked: but typically, the global Apache configuration
is maintained by your provider (though you usually have some means to customize
parts of it).
Create the symlink from public_html to
They like gave you a command like (maybe not exactly)
$ ln -s ~/rails_apps/NinetyNine/public public_html
That is something that is intended to be run on your webhost, from a command prompt,
at the top of your home directory.
Look for docs on bluehost for finding out how to get SSH shell access.
That's where you'll enter the command.
More generally, however, you want to make sure you read the docs on how your
provider wants you to upload applications. Bluehost seems to have very nice
docs here:
https://my.bluehost.com/cgi/help/rails
Why your hosting provided said it was out of scope.
You're a beginner, and that's officially OK. Welcome!
But if you asked them a question like "Do I enter these commands on my computer
or yours", they are definitely going to politely respond that this out of scope;
meaning -- "We can't hand-hold you through this". If you ran a gas station and
someone asked you how to use the pump, you'd tell them. But if they then asked
"OK but do I put the gas in my car or yours?" you'd be reluctant to answer, because
there's some fundamental missing.
So how do I get more pointers, directions on this stuff?
Lots of approaches. By the far the best is to do as much stuff as you can on
your own computer. In your case, you could easily set up your own Apache
(Macs and Linux frequently ship with it - readily installable on Windows), and
that would clear up a lot of the conceptual issues.
Good luck!
I am a novice with Spring.
I am looking to resolve conflicts between #RooEntity and #RooJpaActiveRecord. I have used the typicalsecurity addon to an existing project which used more recent versions of Roo (#RooJpaActiveRecord). I was wondering if there's a workaround or a specific way to address this issue. I am not able to run the project on the internal web browser. I receive the HTTP Status 404 error.
Any help or suggestions would be greatly appreciated!
#RooEntity is no longer the annotation that you have to use.
Replace it with #RooJpaActiveRecord and run the Roo shell again.
Regarding the web project, the annotations belongs to the spring-roo-annotations.jar (or something like that) that maven puts in your WEB-INF/lib folder when deploying the war application.
You need to have the appropriate jar dependency (I mean, the correct version) depending on the annotation that you have in your code.
In order to see more explanation, maybe you can provide your server stack trace.
I am in the process of evaluating several service frameworks and one of them is OpenRasta.
Despite being taken a bit aback for the lack of organization (multiple source code repositories, lack of binary downloads, outdated build instructions and the end result of the build, OpenRasta.dll, has version 0.0.0.0 after building the openrasta-core repository), I managed my way to start building a site with a service that serves a bit of Xml (I did include OpenRasta.Hosting.AspNet and configured the handlers and modules as per IIS or Cassini).
But the very first time I hit the site (both IIS Express and VS Dev Server) I get a ArgumentNullException coming from the PipelineStage.cs. Apparently the pipeline.CallGraph property is null.
My configuration source is a mere:
ResourceSpace.Has
.ResourcesOfType<CatalogCollection>()
.AtUri("/catalogs")
.HandledBy<CatalogsHandler>()
.AsXmlDataContract();
As I mentioned I am using the code I cloned from the openrasta-core repository as of yesterday.
Thanks in advance
