Cant launch Tomcat4.1 : ClassCastException: sun.net.www.protocol.http.HttpURLConnection

[Mike Niemaz <ni...@xrce.xerox.com>]

Hi all,
    I'm trying to upgrade from Tomcat3.3 to Tomcat 4.1.
    When launching catalina, I get the following error:

Does anybody know why?
The same code worked prefectly under Tomcat3.3.
I'm using the same jdk, same external jars.
My first thought was that T4.1 was loading differently.
I tried to force it to load my jars first but with no results ;-(
Before this error, I get a parsing error but I don't think it is related.
