Using a HTTP destination through a HTTP proxy

Question

Hi there!
I have written a Web Dynpro application that connects to a web service using a web service model. The request is configured to use a HTTP destination by means of the _setHTTPDestinationName() method. I configured the HTTP destination in the visual administrator and it uses Logon ticket to authenticate.
All this works perfectly in my test environment. Unfortunately in my production environment the web service must be accessed through a HTTP proxy and I could not find where to configure the proxy settings for HTTP destinations.
I found some information about "open a transaction in SICF" an so on which doesn't help me because I have no ABAP client.
I found some information about configuring proxies in the NWA but this does not seem to apply to my NW version, wich is 2004 SP16.
Any clues?
Thanks in advance.

Hi Olivier,
thank you for your reply.
Is there really a possiblity to configure a proxy for any given HTTP Destination in ABAP? Because if there is, I cannot believe that there is no equivalent in Java. As there is no such a thing as a HTTP Destination "for ABAP" and a HTTP Destination "for Java", what would happen if I used the HTTP Destination with proxy settings created in ABAP for my Java program?
There is another way to use a proxy which I found by analysing the generated Java classes of my web service model. You can do the following:
SomeServiceImpl service = SomeDMSModel.getServiceImpl();
service.setHTTPProxyResolver(new HTTPProxyResolver() {
  HTTPProxy proxy;
  public HTTPProxy getHTTPProxyForHost(String host) throws RemoteException {
    if (this.proxy == null) {
      this.proxy = new HTTPProxy();
      this.proxy.setProxyHost("proxy.company.com");
      this.proxy.setProxyPort(1234);
    return this.proxy;
This is NOT a good way to do it, as it transfers a portal administration task to the programmer, but it shows that the functionality is present in Java.
So I haven't given up on finding where it has to be configured...
