I&#39;m trying to remember what&#39;s the problem..<br>But for what I remember it could be something like: <br>you define the variable claim with type <font><font size="2"><u>com</u>.<u>csatp</u>.<u>svc</u>.<u>rulesmgr</u>.claim.Claim</font></font><br>
<br>did you change the variable type, for example adding a new variable from a different type into the claim variable?<br><br>if not, can you post the stack trace about the class cast exception?<br>to know about from which class is trying to cast...<br>

<br>Obviously this is a
