Can you send a java class and sample xml file and report design that it uses that has the problem so I can test it? Thanks!

<p>Just an update ... we tried to run this code in standalone java application and then 3.7.2 tomcat server and it works.</p><p>It was generating dynamic PDF.</p><p> </p><p>But somehow it is still not working in our existing tomcat project, we are guessing it might be the jar conflict introduced through maven in last 2 weeks. Only change which we can see is the mockito 1.9.5 version. I have removed that from parent jar but still it is not working in the project.</p><p>Any suggestion will be helpful.</p>

<p>Very weird. What if you re-download the runtime? Or try the OSGi runtime instead of the POJO runtime?</p>
