Hi

The HP Java is developing so quickly I would advise you to go to

www.hp.com/go/java

And download the latest verison available.

It is quite possible that this works there.

Make sure in your ../tomcat area your tomcat.properties has the classpath's defined - for example:
wrapperwrapper.classpath=/opt/java1.2/lib/tools.jar
wrapper.classpath=/opt/java1.2/lib/dt.jar
wrapper.classpath=/opt/java1.2/jre/lib/rt.jar

I also recommend getting an update - you are pretty far back - there is an update bundle out on hp's java site.

Your error looks like a tomcat configuration issue, but to test, you may want to start a trace on your listener on the database side to see if anything is coming through

to analyse your problem you should test :

1) try to launch your application with the option :
-classic
with that you will disable the hotspot compiler


2) do have this problem if you have a Xserver opened and a DISPLAY set ?
