Java.lang.NullPointerException in persistent Hibernate class

I have a persistent Approvisionnement class in my .hbm.xml file:

   <?xml version="1.0"?>
   <!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD//EN"
 "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd" >

but when I try to compile the project in Eclipse I get this error:

You get NullPointerException

from org.jboss.mx.loading.RepositoryClassLoader

, which usually means that the JBoss classloader has jumped out of the shark and is in a fatal state.



Restarting JBoss will usually fix the problem.
