How can I configure the HTTP proxy for a Web Service client running in JBoss 4?

[M. Justin]

Using NetBeans 6.8 I managed to write a JAX-WS Web Service client for a service which runs in the Internet.

Within NetBeans, communication through the HTTP firewall works fine.

Now I tried to run the client in a Servlet in JBoss 4.2.3.GA, here the request fails with the message:

HTTP transport error: java.net.UnknownHostException: wwwcie.ups.com

So I guess that the VM which runs the Servlet does not know the proxy. I tried to set the proxy system properties in the Servlet code, and in the standard JBoss configuration file using the PropertiesService - without success.

Many thanks in advance!
