[jboss-dev-forums] [Design of POJO Server] - Exception serializing DeploymentUnit

[bstansberry@jboss.com]

While developing a test for my work on JBAS-5822, stumbled on a problem with serialization of DeploymentUnit.

My test was based on org.jboss.test.deployers.AbstractDeploymentTest, and called its assertDeployed() method, which ends up using an MBeanServerConnection to invoke the "getDeploymentUnit" operation on the server-side MainDeployer. That call fails in marshalling the DeploymentUnit:

The structure of the deployment:

xxx.sar
++ META-INF
++++ jboss-beans.xml
++ valuefactory-service.xml
++ org (classes)

This isn't holding up my JBAS-5822 work; I don't need to invoke assertDeployed() in my test since I later invoke on the deployed mbeans anyway.
