I installed jBPM 4.3 on Jboss 5.1 after making required changes in the build.xml within the install Folder. I deploy the sample examples into JBOSS and then try to run one of them as JUNIT test. However I receive this error : ## EXCEPTION ########################################### 17:24:56,456 INF | [DefaultCommandService] exception while executing command
