Hi All,

I have created a simple standalone project for JBPM and Drools. But when I run the application I am getting the following exception:

Exception in thread "main"
java.lang.NullPointerException at org.jbpm.jpdl.internal.activity.RulesActivity.execute(
RulesActivity.java:51) at org.jbpm.pvm.internal.model.op.ExecuteActivity.perform(

Can anybody please tell me what can be the reason for this exception? I have attached my sample application with this. Please find the same and please give me a resolution.
