WLS5.1/SP8 Problem defining JSP class

[BAlappatt]

I have successfully implemented the struts example on Apache/Tomcat but not
able to the same on WebLogic 5.1. I am getting the error:
Problem defining JSP class
java.lang.NullPointerException
at weblogic..servlet.jsp.OneOffJspLoader.<init><JspStub.java:420>

PS. I have applied the fix published in the mailing list for WLS5.1/SP8

Any help would be appreciated
