Hi all,
We have an application deployed on JBoss 4.0.4. Some parts of the application
depend on accessing some web services. We are using Apache Axis 1.4 for that.
We had a need to deploy another version of a running application on the same
server. After doing so, I noticed that the EJB classes are loaded in a shared
class loader, which caused the web application to call the wrong EJBs.
Consequently, we have changed the JBoss configuration to isolate EAR
deployments as follows:
ear-deployer.xml:
attribute name="Isolated">true /attribute>
Then the two applications were successfully deployed on the same server.
However, since then we have started receiving some unexpected exceptions from
the server, when the application is trying to access any of the web services
using the Axis client. The problem is that the exception message is not
descriptive at all, and there is no specific scenario to trigger them. When we
first start up the JBoss, everything works fine. After a certain period of
time, this exception happens and we have to restart the JBoss again to resolve
it.
The exception stack trace is as follows:
Caused by: javax.ejb.EJBException: Unexpected Error
java.lang.NoClassDefFoundError
