Error while accessing probe in non-root user environment

[sfaiz]

I have apache-tomcat-6.0.20, and also using APR and JSVC to run tomcat
as non-root user. When I deploy probe.war it is deployed successfully
but when i access following exception is displayed.

Is there any configuration which I am missing?

Please attach your entire probe.log file here:

http://code.google.com/p/psi-probe/issues/detail?id=196

Be sure to note what version of PSI Probe you are using.  Thanks!

Thanks.  I've asked you a question in the issue.  Let's continue discussing there.

Avihay, assuming you have the same setup as sfaiz, there is a workaround.  Please refer to issue 196:

http://code.google.com/p/psi-probe/issues/detail?id=196#c20

Let me know if that doesn't resolve the issue for you.
