Hi Oved,
After rebasing our POC code with upstream, I tried to follow the below
steps for moving to JBoss AS7. Since a newer version of JBoss (CR1) is
available, I downloaded that instead of Beta1 assuming that it will be
more stable and will contain mostly bug-fixes and hence should work.
However it turns out that the format of standalone.xml itself has
changed and that created/modified by our "deploy" profile doesn't work.
I had to download the "Beta1" tarball to get the deployment to work.
This is just FYI. Please ignore in case you are already aware of this :)
Thanks,
Shireesh

Hey all,
The patches are now pushed!
So please, if you fetch from now on you'll have to perform the actions below.
The wiki was updated as well.
Short list of steps:
1. Download jboss 7.1.0 Beta1b (wget
http://download.jboss.org/jbossas/7.1/jboss-as-7.1.0.Beta1b/jboss-as-7.1.0.Beta1b.tar.gz)
2. Fetch the latest changes from our git repository
3. Change the Jboss home to the new path, both in the JBOSS_HOME
environment variable, and in maven settings file
(~/.m2/settings.xml)
4. Build the engine, with profiles "dep" and "setup". This will put
all the proper configuration files, postgresql driver and make all
the other needed changes in Jboss in order to make it work properly
mvn clean install -Psetup,dep .......
5. In order to run Jboss go to JBOSS_HOME/bin and run ./standalone.sh
A more descriptive set of steps and notes can be found in my previous E-mail
below.
I'm here if you need any help.
Thank you,
Oved

Hey all,
The code changes required to make the engine work on Jboss AS7 will
soon be push
It will, of course, require you to install it, and start working with
it :-)
A separate E-mail will be sent to notify you all once pushed, and
then you'll have to perform the following steps:
1. Download jboss 7.1.0 Beta1b
(http://download.jboss.org/jbossas/7.1/jboss-as-7.1.0.Beta1b/jboss-as-7.1.0.Beta1b.tar.gz)
- There is a newer version, but it has issues in the REST-API, so we
decided to work with the beta version until a proper fix will be
released.
2. Fetch the latest changes from our git repository
3. Change the Jboss home to the new path, both in the JBOSS_HOME
environment variable, and in maven settings file
(~/.m2/settings.xml)
4. Build the engine, with profiles "dep" and "setup". This will put
all the proper configuration files, postgresql driver and make all
the other needed changes in Jboss in order to make it work properly
mvn clean install -Psetup,dep .......
5. In order to run Jboss go to JBOSS_HOME/bin and run ./standalone.sh
6. Look inside the JBOSS_HOME/bin/standalone.conf file in order to
enable jboss debugging (just uncomment the line
JAVA_OPTS="$JAVA_OPTS
-Xrunjdwp:transport=dt_socket,address=8787,server=y,suspend=n")
7. If you have a krb5.conf file you are working with, put it in
JBOSS_HOME/standalone/configuration directory
8. Run Jboss (and be impressed by the startup speed!)
The above will be also added to the wiki page for building the engine
as soon as the patches will be pushed upstream.
Some facts about Jboss 7:
1. It supports both standalone deployment, and domain deployment. We
use the standalone one.
2. Stuff related to the standalone mode can be found in the
JBOSS_HOME/standalone directory:
* configuration - contains the main configuration file called
standalone.xml file, plus some other configuration files
* deployments - that's where your deployments should be. When adding
a new one, don't forget to create a file called
"<deployment-name>.dodeploy" in order to make it deploy.
* log - that's where the log files are written (unless stated
differently in the standalone.xml file).
3. The different modules that come with Jboss 7 are located in
JBOSS_HOME/modules directory
* No more common/lib directory.
* Every module has a module.xml file which contains it's
dependencies in other modules, the jars that are part of the
module, and etc.
* In order to use a dependency from there you have to add
"Dependencies" section to your manifest file (do git grep
"Dependencies" to take a look at some examples done in the engine
source code).
4. Useful links:
* Documentation -
https://docs.jboss.org/author/display/AS7/Documentation
* Class loading changes -
https://docs.jboss.org/author/display/AS7/Class+Loading+in+AS7
* The Jboss community - http://community.jboss.org/wiki
Please send issues/feedback to this mailing list.
Thank you all,
Oved
