Grouper Users - Open Discussion List

[Karsten Huneycutt <>]

Hello --

I'm trying to install the Grouper UI here at Duke on top of an  
existing Grouper 0.6 installation, and I'm running into trouble.   
Here's the exception I'm getting:

---- END ----

This exception happens immediately after the LoginFilter returns  
(successfully!).

First, of course we wrote Duke-specific Subject and Source  
implementations.  These work in our other standalone programs, so I'm  
pretty sure it's not a problem with that.   I've integrated our NetID  
web authentication system into the UI via our Tomcat authentication  
Valve, and I've verified (using "System.err.println 
(request.getRemoteUser())" strategically placed in MyGroups.jsp,  
along with setting swallowOutput to false in the context) that the UI  
code is getting the appropriate NetID.  The Duke Source uses our Duke  
Unique ID as the SubjectID, and getSubjectByIdentifier expects a Duke  
NetID.  I've set my classpath to include all the JAR files in webapps/ 
grouper/WEB-INF/lib and webapps/grouper/WEB-INF/classes, and I've  
verified using groupmgr and grouperq that the configuration files and  
libraries are correct, sufficient and functional.

For reference, I'm using tomcat 4.1.27 on Solaris 9 with Java 1.4.2_04.

Oddly, I'm not seeing any output from Subject/Source interactions in  
my log file, even though I have the following lines in log4j.properties:

log4j.logger.edu.internet2.middleware.subject           = DEBUG, rfile
log4j.logger.edu.internet2.middleware.subject.provider  = DEBUG, rfile
log4j.logger.edu.duke.oit.idms.groupreg.grouper.GroupManager =  
DEBUG,  rfile
log4j.logger.edu.duke.oit.idms.groupreg.grouper.DukeSubject = DEBUG,   
rfile
log4j.logger.edu.duke.oit.idms.groupreg.grouper.DukeSubjectAdapter =  
DEBUG,  rfile

But, I'm not getting the exception I'd expect were there difficulties  
with the subject interaction...

Any pointers on where to look next?

Thanks!

KH
