problem
Does anyone know why the following could occur? It happens not infrequently
with our software. This happens in Tomcat 4.
Thanks in advance for any help.

Rameez

RE: problem
Posted by Kasim <mi...@gmail.com>.
Assalamoalikum
Dear this is due to the variable which you wants to prints its value but
value is not yet assigned. So check out the variables defined in your jsp
page or servlet.Generally some variables value depends on the request .We
extract the parameter from request object and assigned that value to
variables defined locally and then process those variables but while
processing (eg parsing the value of variable) the variable such exception
rises. So please check out the value of variables before processing it.I
hope this will help you to clear the bug which you face frequently...
