process definition 5.2.2 jdk7 xerces

'Process definition' not found - Bonita 5.2.2


Im actually with jboss 4, jdk 5 and bonita soft 5.2.2

I have to up jdk to 7 but i got error if i attempt to load bar on user experience. I get an error on 'process definition' not found and further, an error on sax, it's about xercesImpl.jar (placed in endorsed dir of jboss).

Do you think if it's possible to keep bonita 5.2.2 with jdk7 ? I have to keep xercesImpl.jar too ...
