Hello
I have a web application configured to work in tomcat using spring . I'm trying to add
JBPM workflow engine to my application.
I have configured persistence to work with MySql and JPA 2.0 in persistence.xml. and I
have added a spring bean contaning transaction manager and EntityManagerFactory.
My probleme is I got the error saying *could not parse knowledge* when running the
following:
KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
kbuilder.add(ResourceFactory.newClassPathResource("process/Evaluation.bpmn"),
ResourceType.BPMN2);
KnowledgeBuilderErrors errors = kbuilder.getErrors();
KnowledgeBase kbase = kbuilder.newKnowledgeBase();
The line in green check if there is any errors. it contain [ProcessLoadError: unable to
parse xml : Exception class java.lang.NullPointerException : null]
Any help will be great
Thinx

Did you put : process/Evaluation.bpmn in src/main/resources ?
It should work.

Yes I did put process/Evaluation.bpmn in src/main/resources
By the way, I have the same project in JPA1.0 and it work but when upgrade to JPA2.0 my
database was updated and user are inserted in organizationalentity table
but i have that message saying could not parse knowledge when loading Evaluation.bpmn into
knowledge Builder.
Other think I'm trying to debug KnowledgeBuilderImpl which contain implementation of
"kbuilder.add(resource,type)" but I can't find source (I'm working with
eclipse)
have you any idea about how to do that?

Hi Houssem,
the full stack trace of these could be off help. But it seems that the ResourceFactory
could not find the resource then returning a null at some point.
