Tomcat 4.0.4 - Error 500

["Natarajan, Raj" <ra...@firstcitizens.com>]

I have approx 25 applications deployed on a stand-alone Tomcat 4.0.4
instance. These apps retrieve data from a DB2 database via jsp's using a set
of custom tags. 

I have had three instances so far since the apps went live on 8/28 when all
the apps start returning a 500 Error with this message. 

java.lang.NullPointerException
        at java.lang.String.equals(String.java(Compiled Code))

The only log entry I found is in the localhost_log.2002-09-19.txt

StandardWrapperValve[jsp]: Servlet.service() for servlet jsp threw exception
java.lang.NullPointerException
        at java.lang.String.equals(String.java(Compiled Code))

Restarting Tomcat fixes the problem.

I would greatly appreciate any pointers that would help me resolve this
problem.

Thanks
Raj

You might have to print the full stack of the NullPointerException to 
find out which class could be creating this exception.
