<p>This is because birts libs are conflicting with the ones beeing available in JBoss. I m assuming that you can run birt as a war without having issues. This is because classloading order is different for ear and war. Could you try?</p><p>If it works as war you would be able to change the behaviour of ear using a jboss-classloading.xml (parent-first setting)</p><p> </p><p>Keep me posted</p>
