Hi I am trying to use Jasper (4.0.2) reports with JBoss 6 using an XML file as data source. However, there is a fair amount of over lap of required library JARs and as I can’t exclude the JBoss libs I have excluded any conflicting Jasper JARs. When I run the program on its own all is well however when I re-introduce the JBoss libs I get this when trying to execute anything Jasper related:

The Log4j library it seems to be complaining about is the same version in both Jboss and Jasper so I am confused by the exception.
Can anyone tell me is this a general compatibility problem or is there a safe way to include all required libraries without the conflict?
So the issue was with the inclusion of both the jasperreports-4.0.2.jar and jasperreports-javaflow-4.0.2.jar files. Once the “javaflow” JAR was removed all deployed smoothly.
