Summary:
Exception on second report start Using a ejb3 data source with iReport 1.2.5 I get the
following exception on starting the report. The exception occurs only at the second and subsequent times. The first start works fine and displays the report preview without errors and with the correct result set values.

By the way, what's the recommended way to configure a ejb3 data source? On the first try, I added a jar containing my mapped classes and the persistence.xml to the classpath, but iReport failed to find the entityManager. So, I added the hibernate-entitymanager.jar from the jboss installation, where the main application runs. After that, I got an methodNotFound exception for a hibernate class. I concluded, that the hibernate versions of my jboss installation and my iReport installation are
different. So, I added all *ejb3*.jar and *hibernate*.jar from jboss to the classpath but the exception was still the same. So, finally, I copied nearly all jar-stuff from jboss to the <iReportInstallDir>/lib overwriting some of the original jars. Now, it works except for the described problem which should have another reason. But this is
not the recomended way, isn't it?
