Hi
Further on this thread... (running from eclipse) I am getting the following stacktrace..
java.lang.IllegalStateException: java.lang.reflect.InvocationTargetException
....
Caused by: java.lang.reflect.InvocationTargetException
...
Caused by: java.lang.RuntimeException: java.lang.ClassNotFoundException: Unable to load class: org.drools.persistence.processinstance.JPAProcessInstanceManagerFactory
...
by: java.lang.ClassNotFoundException: Unable to load class: org.drools.persistence.processinstance.JPAProcessInstanceManagerFactory
on bit of an investigation looks like these classes are available in drools-xx--5.1.1 but not there in drools-xx--5.2.0.. all the same on e cant' work with drools-xx5.1.1 as some of the methods are missing which are required for creation of knowledge session.
Including my persistence.xml and java runner class... please have a look....
It will be a big help if someone can share some tips/code... to show it works..
