JBoss deploy error after upgrading app to Grails 2

Question

I've upgraded a Grails app from 1.3.6 to 2.1.1. After some fixing and tidying up, run-app works (for the most part, still some deprecated issues to deal with). grails war also builds without error.

When I deploy into JBoss (4.2.2) however, the same as has been done for the grails 1.3.6 war, I get this error:

So am thinking it's a collision between a catalina class in a lib in the war, and one already in jboss? As it worked ok when it was 1.3.6, is it something that's been added to the 2.1.1 grails tomcat plugin and is it possible to exclude a sub-dependency from a grails plugin?

Thanks.

Answer 1

Found the 'solution', in case anyone else is looking.

The error disappears if I move the declaration of the plugins from application.properties to BuildConfig.groovy. I'm not sure if it's actually "fixed" it or if it caused a clean/reinstall of the tomcat plugin that might have cleared it up, but it removed the error on deploy.

After this I hit another error, with JBoss hibernate libs being older than the ones in Grails 2.1.1 dependencies:

Caused by: java.lang.NoSuchMethodException: org.hibernate.validator.ClassValidator.   
(java.lang.Class, java.util.ResourceBundle, org.hibernate.validator.MessageInterpolator, 
java.util.Map, org.hibernate.annotations.common.reflection.ReflectionManager)

that was fixed by following the instructions here to tell JBoss to use the app's libs instead of its own.
