java.lang.IllegalStateException

[teh j <to...@yahoo.com.au>]

Hello !

I have Tomcat v3.2.1 running a little JSP application
I have developed. If I leave it running for a few
days, I get the error message below for no reason
whatsoever!

The only thing that seems to fix it is if I restart
Tomcat (Tomcat is not integrated with Apache here, it
is running as a standalone)

Can anybody shed some light as to what is happening
and suggest a way to fix it?

thanks!
Jason
