Hi, 

  I'm currently building an application using JSP. When I run my 
application, very often, I would encounter javaw.exe error (popup 
message), a kind of illegal operation message box. It will then stopped my 
server. 

  What are the possible reasons, and can anyone provide me with solutions 
to solve my problem? 

  Initially, I was using JDK 1.2.1. Now I have upgraded it to JDK 1.3 and 
I still have the problem.

  Could it be due to a problem that occurs in my connection pool?

  I look forward to any replies. Thank you and your help towards the 
success of my application deployment will be deeply appreciated.
