call Web Service method through a Proxy

[Dimitris Micha]

Hi,
I am working with Java in Netbeans.
I have created a WS client from an existing wsdl and managed to create a service object, getPort() on it
and call the operations of the Service.
But i want to use a Proxy to do this not like this...
I have tried calling

      System.setProperty("https.proxySet", "true");
      System.setProperty("https.proxyHost", theHost);
      System.setProperty("https.proxyPort", thePort);

But this is not the solution I want as this changes the properties of the whole System and I do
NOT want that...
Any pointers/solutions/examples are welcome.
THank you,
Dimitris
