wildfly 10: java.lang.ClassCastException: org.dom4j.DocumentFactory cannot be cast to org.dom4j.DocumentFactory

Question

I have a maven application that works fine in wildfly 8.2, but when Ideployed it in wildfly 10 this error happened:

[2016-02-21 11:22:08,411] Artifact Sarama         


        

Answer 1

The other suggestions here either did not work for me or did not apply to my project. I found a possible solution in this blog. Basically it says to add Dependencies: org.dom4j export to {your war}/META-INF/MANIFEST.MF. I'm running Wildfly 10 and doing so in both my ear and ejb project seems to have worked.
