Hi Claus,
You are using Apache as a proxy, i.e., client --> Apache ---> Tomcat, right?
There is an error: unsupported HTTP response code: 404 (Not Found). That
means that the URL of the application is incorrect.
You say JNLP is working fine. What is the ULC application URL that you are
specifying within the .jnlp file? Are you using the Apache Load balancing
when you connect to your application with the JNLP client?
Please also see the attached mail and the following URLs (earlier answers to
you) for more info:

Kindly let me know if this helped.
Thanks and regards,
Janak
