Here's part of the stack trace: "at de.adesso.tma.test.ejb.TestMessageBean.onMessage(TestMessageBean.java:212)"
Can you tell us what is at line 212 and the types of any objects referenced in it (including packages)? I'd also try to figure out what version of org.apache.activemq.ra.ManagedConnectionProxy you're using and which JAR it's coming from. I'd probably attach a debugger and step into the classloader when it's loading that class, but you might be able to figure it out using jar tvf or another method I haven't thought of. Tim .. some more thoughts: The MDB is in fact not compiled or linked against any concrete ActiveMQ classes. The MDB uses only the standard interfaces defined in the package javax.jms. I need the ActiveMQ client library in my developement project only to run a JUnit test, which sends and receives messages. So there is no need to include the ActiveMQ client library in the EAR, which contains the MDB. So, if there are conflicting classes, they must be provided by WildFly.
