Question

I am running a grails test run-app all day with my application and it is fine. I type “grails prod war” to get a war, and dump it in the webapps folder of my tomcat install. Now i get the message like so:

What is causing this? I have the docx4j jar in my WAR for sure, and it is there in the web-inf lib folder as well.

Answer 1

You’re getting a java.lang.NoClassDefFoundError, not a java.lang.ClassNotFoundException. The class is being loaded, but a class that it depends on (directly or indirectly via another class) isn’t there. You’re most likely missing a jar that docx4j requires as a dependency.
