Error in deployment of EAR JOnAS 4.1.2

[Lofi Dewanto <dewanto@xxxxxx>]

Hi Community,

IMO, it is important to have a good deployer for the EAR in JOnAS.

After trying many things I come to this conclusion, also
see my older mail at:
http://www.objectweb.org/wws/arc/jonas/2004-10/msg00126.html

1. Under Win2000. The long path name makes it impossible under
Win2000 an EAR file to be deployable. I tried everything:
- Standard EAR.
- EAR with a WAR (exploded) inside it.
Nothing seems to work. Because JOnAS 4.1.2 does not support
- Exploded EAR deployment and
- "Naked" deployment (see my older mail at:
http://www.objectweb.org/wws/arc/jonas/2004-10/msg00103.html

So, you have no chance to deploy a "real world" EAR in JOnAS 4.1.2.
I successfully deployed a simple EAR from my PiggyBank example
but for a "real world" application like OpenUSS (with long package
name and path name, with more than 100 EJBs) it is impossible.

2. Under Linux. You don't have the long path name problem but I
still get a problem with "#". See my older email at:
http://www.objectweb.org/wws/arc/jonas/2004-10/msg00126.html
-> 2. Error in executing the web app

So, it is also impossible to deploy a real world application
with EAR deployer in JOnAS 4.1.2.


SOLUTION:

Here is the HACK-HOW-TO (so that you don't need to spend
your whole nites and days in the front of computer like me ;-))
which is working for both OS:

1. Deploy all your EJBs within the EAR file. Don't put your
servlet WAR in it (comment it out from your application.xml).

2. Deploy your servlet WAR in "exploded" way. Add the jonas-web.xml
to put this <java2-delegation-model>false</java2-delegation-model>.
Put all your libs and ejbs within this exploded servlet, so your
servlet can find the ejbs:
/WEB-INF/lib/..

3. Edit your jonas.properties, like this:

jonas.service.ear.autoloaddir   ../deploy/ear-package
jonas.service.web.autoloaddir   ../deploy/war

So you deploy the EAR and the WAR in different classloader.

4. Run your JOnAS 4.1.2, you'll see it says JOnAS version 4.1.2 is
ready!

I really hope that this part will get better in the next coming release,
also for Enhydra Enterprise 6.x!

Hope this helps!
