Hi Claus, Perhaps it is a proxy authentication issue.
Could you tell me how you are authenticating the proxy? The authentication behavior in Java 1.5 could be different from that in Java 1.4 See http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6226610 Thanks and regards, Janak -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of [EMAIL PROTECTED] Sent: Friday, April 20, 2007 1:28 PM To: [EMAIL PROTECTED] Subject: [ULC-developer] Java Webstart Problems Hello evreybody, well, that's not directly an ULC Problem but we often run into it. Our ULC Application is hosted on Apache Tomcat/5.0.19, Java 1.4.2_03-b02, Windows 2000 and is supposed to be started via Java Webstart on a HTTPS connection. Trying to connect form Java 1.4 based clients gives us HTTP errors 404 or 501, connections from Java 1.5 based clients just work fine. Could somebody please give us a hint how to find out what the real problem is ?
