Hello all,

I posted this topic on the JBoss Seam Forum and I got redirected here.

I have a very strange problem with our application using JBoss Seam 2.0.0.BETA1.

We have two annotated service objects, CORBAOrb and AlarmConsumer. The latter one has a dependency on the first one (we used the @Depends annotation).

As one would expect, the dependency is satisfied when the EAR file is deployed on to JBoss AS 4.2.0.GA. That makes me think that the annotations are correct and I do not have to include the source code here in my post.

The following is the relevant extract from the server.log file. Everything works fine because the CORBAOrb MBean is started before the AlarmConsumer MBean, which depends on its services.

However if I run the code as a Seam TestNG integration test where our test extends SeamTest, the deployment order is different.

I used the three jars coming with JBoss Seam 2.0.0.BETA1 in its lib directory: jboss-embedded-all.jar, hibernate-all.jar and thirdparty-all.jar.

The following printout from TestNG shows that the same two MBeans are started in the wrong order, causing exceptions:

Did anyone experienced this problem before? Is this a known issue? More importantly, is it a limitation of the Embedded EJB3 container?

As far I can see, the behavior of the MCKernelAbstraction is different from the JmxKernelAbstraction.

We tried to debug through the Embeddable EJB3 container but it is unclear what went into the jboss-embedded-all.jar file in terms of compiled source code (list of CVS or SVN projects, branches and tags/labels)? We checked out the 4.2.0.GA source code and also JBoss Microcontainer 2.0 but the lines did not match.

Any help would be really appreciated.

We think that Seam is a great enabling framework to write simple code and the idea that you can write integration tests for your Seam application when/while you are developing is brilliant!

Only if we could get consistent behavior between the fully-blown JBoss AS and the EJB3 Embeddable...
