[rules-users] Exception in thread "main" java.lang.ClassCastException:

[srinivasasanda]

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));
