tomcat shutdown

Dear all,

Tomcat was installed as an NT service but it will stop automatically. Below 
are some of the errors found in the logs consistently and not only on the 
day it shuts down.  Can someone advise on the errors and how to prevent 
tomcat from shutting down?

Please help.  I really am at my wits' ends.  Thank you.

Seems that something is going on in your servlet on line 144... You're not
correctly handling a NULL value for some object. It doesn't look to be a bug
in Tomcat.
