Enhydra and JOnAS / EJOSA Problem

[Lofi Dewanto <dewanto@xxxxxx>]

Hi JOnAS and Enhydra community,

I tried to upgrade EJOSA with JOnAS 3.3.6 and Enhydra 5.1.7.
Everything seems to be ok except my written JOnAS service for Enhydra.

I wrote a JOnAS service to run Enhydra within the JOnAS container
(I just drop the Tomcat service and run the Enhydra as service).
With the older JOnAS 3.1 and Enhydra 5.0, I had no problem running this
service.

But now I always get this exception:
   [java] org.objectweb.jonas.server.Server error:

Simply adding enhydra.jar (5.1.7) in the classpath of JOnAS (3.3.6)
will show me the same exception. It seems that enhydra.jar has a
conflict with JOnAS libraries. Any ideas?

I really need your help as I need to have this service to show the
integration between Enhydra and JOnAS.

Thanks and greets,

BTW 1. I almost finish the EJOSA 2.0 which now added a "model" layer
(use AndroMDA for Model Driven Architecture). Now, you can draw some
simple UML diagrams and you get:

1. Interfaces for the "specification". Support on "standard
Java interfaces" and also EJB interfaces.
2. First implementation of the "business" layer. This supports
EJB, DTO, Hibernate. I also plan to add JDO.
3. Pesentation Layer "presentation" using Enhydra Framework -
EAF - Presentation Objects.

The JOnAS example "Alarm" is already added with the model layer,
so you can generate the whole EJB interfaces through the UML model.
Very nice :-) If you are interested to play:
1. Checkout the code "ejosa-revo" from ejosa/ejosa-revo/* CVS.
2. Download and install the ext-libs (external libraries incl.
everything, no need to download anything else) into ejosa-revo/ext-libs.
Download:
http://prdownloads.sourceforge.net/ejosa/ejosa-revo-ext-libs.zip?download
3. Run dev-all/build/build-all-components.xml to compile the whole
examples.

I will update the manual and put the new version in the download page as
soon as I get rid the JOnAS service problem.

BTW 2. Alfred, when will you release the Enhydra 4 (with JOnAS
included)?
