Shibboleth Developers

downloaded the new build this morning.... and I'm just seeing 
weirdness.... all suggestions welcome.....

I'm using tomcat 4.1.18 LE -- same as before.....

I'm getting

        Internal Server Error

in my browser window, after authenticating but before I see the 
POST/redirect screen....

neither apache/error_log and catalina.out seems to shed any light...

I edited log4j.properties to turn on verbose logging, but still nothing....

tomcat:8080 is working fine.....

two unusual occurrences:

1) first time I ran  the new  origin, the HS stopped, and the 
catalina logfiles noted that  I hadn't defined

        edu.internet2.middleware.shibboleth.hs.HandleServlet.siteName

which I couldn't find in the sample file, or in the doc... weird...

I set this  to brown.edu, and things went better.... or at least 
seemed to go  further...

2) catalina.out contains this error message -- should I worry? this 
appears after I hit the HS....
