[kepler-dev] metacat question

[Eric Magaha]

Hi Ben,

Yes I replaced the server name for submission on the listserv.

Ok.  Hitting the servlet directly with the parameters you specified gives me
the 500 error, with a stack trace showing a NullPointerException in
AuthSession.java:85.  I will troubleshoot.

Thanks!

Eric
