Hi Vishal,<br><br>We found the JANINO compiler to be less than ideal (plus we wanted to use Java 5 syntax which only JDT supports). <br><br>I think WebSphere has gone to <a href="http://6.1.0.5">6.1.0.5</a> just recently.<br>

<br>Thanks Steve,<br>I tried PARENT_LAST option, but that did not help. I will consider upgrading<br>to <a href="http://6.1.0.3">6.1.0.3</a>.<br>in the meanwhile i have the solution to this, by using JANINO instead of<br>
