Hi One and All,
I used resource scanner in my program to update changes automatically.
Every thing works fine.
I had one method Method1 to create knowledge base.
I had another method Method2 :
with an infinite loop where i had a set of facts insert into in
command list, and ksession.execute.
Now i tested the application whether the changes are applying or not :
After adding or modifying rule ,I validate and build package.
Now from infinite loop i got an error at line
ksession.execute(CommandFactory.newBatchExecution(cmds));
Exception in thread "main" java.lang.ClassCastException:
pricing.specification cannot be cast to pricing.specification
