Have not found answer anywhere else, so I thought I'd try here.

Is anyone successfully using WebStart 1.2 with JBoss 3.2.x/Tomcat 4.1.x?

I am having a problem deploying a WebStart (1.2) application on 3.2.2RC3 w/ Tomcat. When the JNLP file is downloaded, WebStart errors out, saying it can't find the JNLP file. I can see the JNLP file coming over the network (Ethereal), but it never gets written to disk. Odd, since IE reads the HTTP headers and gets the MIME type, because WebStart *is* launching.

When the server is Jetty (JBoss 3.2.2 RC3 + Jetty 4.2.11 tarball), everything works fine. I take the same EAR file and drop it into the 3.2.2RC3 + Tomcat 4.1.27 server, and it doesn't work. What's stranger is that the problem only seems to be on Windows based browsers (IE6 and Moz). When browser is Linux Mozilla, it works fine.

I trapped the HTTP traffic, and it looks like so. In both instances, the content looks to be identical. There is some difference in the headers, but nothing looks obvious to me.

Any ideas? Any help would be appreciated.
