| Error description
Customer is receiving a NullPointer Exception at high loads. Th
e code generated by te JSP compiler is not checking for valid ou
t "JSP writer" before doing an out.flush. This problem occurs o
n WAS 3.5.x. Local fix
The NullPointer exception is caused by a problem with sessions.
If the customer fixes the session problem then they will not get
the exception. However, we still have the problem with the JSP
compiler not checking for vaild out"JSP Writer" before doing a
flush. Problem summary
****************************************************************
* USERS AFFECTED: WebSphere Application Server 3.5.5 *
* developers using jsp processors 1.0 and 1.1. *
****************************************************************
* PROBLEM DESCRIPTION: NullPointerException in JspServlet *
* is masking the actual exception *
* being thrown. *
****************************************************************
* RECOMMENDATION: *
****************************************************************
Error handling is not properly checking for valid objects
when an exception is thrown. If an exception is thrown
prior to the initialization of the PrintWriter, a
NullPointerException is thrown thus hiding the
true exception that caused the jsp to stop processing. Problem conclusion
Modified the generated java code to verify that the
PrintWriter object is not null before making any
calls involving the outputstream in the exception
handling code. Temporary fixComments
