no error.
these are my packages:
1)src/main/java - com.sample : here there are the ProcessTest.java class and myClassWorkItemHandler.java (where there are the metod abort and executeWorkItem);
2)src/main/resource - META-INF: here there are the .conf file and the drools.rulebase.conf file
I repeat, last week I haven't any problem with new workItem...
