Grouper Users - Open Discussion List

["GW Brown, Information Systems and Computing" <>]

Keith,

Unfortunately there isn't enough detail in the Java error to determine the 
exact cause of the problem. Typically the first problems found arise from 
the database or a Subject Source not being available, however, they tend to 
give different errors.

A NullPointerException is being generated in the code responsible for 
preparing the browsing template, which suggests that the Root Stem cannot 
be found.

Would you confirm that the QuickStart HSQLDB database has been started. 
There is a build.xml file in the grouper-qs folder. Executing 'ant db' in 
this folder starts the HSQLDB database in server mode. If the database is 
not running, restart tomcat after starting the database.

If the database is running, I would usually debug the web application in 
Eclipse (or another Java IDE). At this point it would probably be easiest 
if you could re-package up your QuickStart with your config and make that 
available to me.

Gary
