Hi Steve,

This is the same error I encountered when trying to get the grouper-ui operational in Weblogic 9.2. The core problem was Weblogic 9.X as a strict 2.4 servlet container was puking on struts-el. See the 'Grouper UI in Weblogic 9.x' thread for more info.

I've setup a working instance of the grouper-ui on JBoss 4.0.2 and Tomcat 5.0.30 so I'm a little baffled that it wouldn't work on a Tomcat 4.x version as you pointed out.

Hope that helps.

I trying to get the UI up and running and I'm hitting an interesting problem. I'm just trying to setup the UI on my laptop using basic tomcat authentication. I can authenticate to grouper UI and get the "My Membership" page loading. But the "My Membership" page never finishes loading. It looks like once the load gets to the bottom of the page an exception is thrown. See stacktrace below.

It doesn't seem to matter which page it is, except for the welcome page, I get the exception at the end of the page load. I've been able to get enough of the "My Membership" page loaded to click on one of the group links to see that the problem isn't page specific.

Once the exception is thrown, the UI gets stuck in some endless loop redisplay the same error page with the same stack trace. So, even the error page is throwing the exception.

I haven't made any modifications to the UI outside of the file. I've tried running the UI on both Tomcat 5.5 and 4.x and get the same behavior. I just downloaded the UI from the website yesterday.

Thoughts? Suggestions?
