Hi Claus, >let me try to put our problem more clearly: >javaws http://kom-prd.mv.com:8975/lv/app/lv.jnlp direct to server, >works fine (JNLP launcher).
>javaws http://komlix-prd.mv.com/lv/app/lv.jnlp via loadbalancer, >works also fine (JNLP launcher). This will work as the jnlp file is served up by apache. What matters is the ULC application URL that you are specifying in the jnlp file. Can you tell me what is it? >java -jar launcher.jar http://kom-prd.mv.com:8975/lv/lvapp/ direct >to server, works fine (Standalone launcher). Ok as expected. >java -jar launcher.jar http://komlix-prd.mv.com/lv/lvapp/ via >loadbalancer, fails (Standalone). The launcher thinks that your ULC application is running at the above URL. This is not the case, your app is running within tomact. >with the stacktrace given below.

I checked the application URLs in the JNLP file and >servlet mappings in web.xml. I would like to know what url are you specifying with the JNLP file. The JNLP launcher uses that URL to connect to the ULC app. >Do you have some idea how to track the problem down ? As I said in my earlier mail, when you use Apache as a proxy, you have to worry about the URLS and my earlier mail had hints on how to take care of URLs. This will depend on your apache-Tomacat config and the way you rewrite URLs. I hope this helps.
