I am using jboss 3.2.6 tomcat 5.0 (I have no choice in these) Eclipse 3.0.2, myeclipse 3.8.4+QF2.

I am trying to write a “simple” hibernate+ejb+struts application.

My enterprise application project has a web project and an ejb project with hibernate capabilities.

I can test the hibernate layer as in the hibernate quickstart example – it works fine.

Using an xdoclet-based session bean, I replaced the business method with a method that looks just like the successful test.

I then call that method from my struts action.

Below is part of the resulting stack trace. Any suggestions are welcome.

Moving to OT > Soft Dev, this is a hibernate issue.

You might try searching for the exception in the hibernate forums, you may have a better chance of finding someone in a similar boat.

[johnjoreilly]

OK, I solved the problem by manually copying ehcache-0.9.jar from my workspace to jboss-3.2.6\server\myserver\lib. It seems like that should have been done during MyEclipse deployment – in which case it WOULD be a MyEclipse issue, and not a Hibernate issue, or am I missing something?

[Scott Anderson]

Actually, for enabling core capabilities of the *server* itself, you need to do as you did. It looks like you’re installing a new caching manager and that is a server-specific configuration, not an application-specific configuration. For adding additional jars / capabilities to your *application*, you can use Window > Preferences > MyEclipse > JBoss 3 > Paths > Append to classpath.

Hope that clears it up a bit.

[johnjoreilly]

So, all those jars cluttering up the package explorer do not get deployed along with the rest of the project? That seems odd to me.

[Scott Anderson]

Yes, they do get deployed if they’re in WEB-INF/lib or you’ve turned on portions of our extended deployment support as detailed in the Advanced section of the Web Development Quickstart here: http://myeclipseide.com/enterpriseworkbench/help/topic/com.genuitec.myeclipse.doc/html/quickstarts/webprojects/index.html#dependent_projects

[johnjoreilly]

But, what if, as in this case, the jar is not part of a web project, but part of an ejb w/hibernate project called ‘foo’, and resides in C:\eclipse\workspace\foo\lib and appears directly under foo in the package explorer?
