Grouper Users - Open Discussion List

[David Smith <>]

Environment:

RedHat Enterprise Linux 5 Desktop running on kernel 2.6.18-194.el5
Tomcat 5.5.23
JRE 1.6.0_19

I've followed the instructions in the Quick start documentation to 
deploy grouper to Tomcat 5.  After deploying the webapp to Tomcat, 
starting HSQL through ant, and starting Tomcat, I see the following 
startup error occur in logsgrouper_ui.log:

I've verified through the db-ui that the grouper_dll table does exist 
and the tomcat log reports some of this same exception in its own log.

Is this an issue that can be resolved in one of Grouper's config files, 
or will a source code change be necessary to fix the bug?  This issue 
appears in both versions 1.5.2 and 1.5.3 and causes the UI webapp to be 
inaccessible through the browser (reporting the error "_The requested 
resource () is not available.")_.

Thanks,

David
