I don't know what it is yet. Just this week I've been trying to track down errors like this so we can have a more stable deployment system.
We do not have logging turned on on that webapp, so I can't see find actual request. Can you help Paul or Jennie install and run a personal proxy? Personal proxies are a very useful tool to have as a developer so it is worth the time to figure out how to use them. We've looked at these two: http://www.xk72.com/charles/ http://www.owasp.org/index.php/Category:OWASP_WebScarab_Project We've used Charles more, but webscarab is open source, and seems more flexible. I've been planning to figure out WebScarab the next time I need one, so this seems like as good a time as any. After you have the personal proxy running then make the same request again. If the proxy is working properly it will log the http communication between the local computer and server. I'm assuming that running the javachecker isn't critical for Jennie or Paul so it is ok go slow on this and gather as much info as we can. Scott ----- Notes about what I did to try to track down this problem: I first tried this: curl -I http://tels-develop.soe.berkeley.edu:8080/maven-jnlp-snapshot/jnlp-tests/jardiff/javachecker.jar?version-id=1.0 That should be making the same request that webstart is to get the jar file. I get a response of: HTTP/1.1 200 OK Server: Apache-Coyote/1.1 x-java-jnlp-version-id: 1.0 Last-Modified: Wed, 23 Aug 2006 15:21:14 GMT content-encoding: Content-Type: application/java-archive Content-Length: 11740 Date: Fri, 25 Apr 2008 12:52:24 GMT In the past when I saw errors like this I would just restart the servlet to see if that would fix it, but I'm been trying to figure out these problems so we don't need to keep restarting the servlet. Here are some notes I made about it before: http://www.telscenter.org/confluence/display/PAS/Issues+with+JNLP+Download+Servlet Notice the same error is reported. So I would guess whenever the webstart client gets a 500 error from the server it reports: "missing version field" instead of "server error". One thing that is odd is the servlet being accessed. It is: http://tels-develop.soe.berkeley.edu:8080/maven-jnlp-snapshot Instead of the normal: http://tels-develop.soe.berkeley.edu:8080/jnlp The tomcat manager reports there is plenty of memory available: http://tels-develop.soe.berkeley.edu:8080/manager/status I also checked this particular webapp: http://tels-develop.soe.berkeley.edu:8080/manager/status/all#18.0 It has been running since Dec. 07.
