[fishcat] How to setup proxy in jax-ws client generated from wsdl without using System.properties ?

I'm trying to test jax-ws clients in my application with Glassfish. The application works fine at home, but at the office I have to use proxy.

My problem is that I have to use proxy for one client only and not all of them.

It works fine for this client if I use :

System.setProperty("https.proxyHost", util.getProperties("proxy.host"));
System.setProperty("https.proxyPort", util.getProperties("proxy.port"));

but the problem is that the others clients stopped working because they don't need a proxy.

I want to test it for Glassfish 4, but I have no idea how to do that.

PS. All the clients code are generated from wsdl.

thanks
