Calling abap web service from webdynpro

Question

hi,
i have a problem in that i am trying to call an ABAP web service published from r/3 in webdynpro. when i browse to the url generated by the r/3 application server it asks for my r/3 user name and password (not to be confused with http proxy user name and password). now when i enter it, i can see the generated wsdl without a problem. pressing escape gives me the standard 401 error.
please note this is the r/3 username and password which i am required to enter. when i try to get to the webservice in webdynpro. here is my code:
  public void wdDoInit()
    //@@begin wdDoInit()
    try
          Request_YYMJ_WS_TEST1_DEF1_yymjServiceWebTest1 reekvesta = new Request_YYMJ_WS_TEST1_DEF1_yymjServiceWebTest1();
          reekvesta._setPassword("userid");
          reekvesta._setUser("password");
          wdContext.nodeRequest_YYMJ_WS_TEST1_DEF1_yymjServiceWebTest1().bind(reekvesta);
          wdContext.currentRequest_YYMJ_WS_TEST1_DEF1_yymjServiceWebTest1Element().setWfKunnr("0000000011");
          wdContext.currentRequest_YYMJ_WS_TEST1_DEF1_yymjServiceWebTest1Element().modelObject().execute();
          wdContext.nodeResponse().invalidate();
    catch(Exception e)
          IWDMessageManager msgMrg = wdThis.wdGetAPI().getComponent().getMessageManager();
          String msg = e.getLocalizedMessage();
          if ((msg==null) || (msg.length()==0))
               msg = e.getMessage();
          msgMrg.reportException(msg,true);         
    //@@end
i have also tried it this way:
  public void wdDoInit()
    //@@begin wdDoInit()
    try
          Request_YYMJ_WS_TEST1_DEF1_yymjServiceWebTest1 reekvesta = new Request_YYMJ_WS_TEST1_DEF1_yymjServiceWebTest1();
wdContext.nodeRequest_YYMJ_WS_TEST1_DEF1_yymjServiceWebTest1().bind(reekvesta);     wdContext.currentRequest_YYMJ_WS_TEST1_DEF1_yymjServiceWebTest1Element().modelObject()._setUser("userid");     wdContext.currentRequest_YYMJ_WS_TEST1_DEF1_yymjServiceWebTest1Element().modelObject()._setPassword("password");
wdContext.currentRequest_YYMJ_WS_TEST1_DEF1_yymjServiceWebTest1Element().setWfKunnr("0000000011");
wdContext.currentRequest_YYMJ_WS_TEST1_DEF1_yymjServiceWebTest1Element().modelObject().execute();
          wdContext.nodeResponse().invalidate();
    catch(Exception e)
          IWDMessageManager msgMrg = wdThis.wdGetAPI().getComponent().getMessageManager();
          String msg = e.getLocalizedMessage();
          if ((msg==null) || (msg.length()==0))
               msg = e.getMessage();
          msgMrg.reportException(msg,true);         
    //@@end
in both instances i get the error:
Service call exception; nested exception is: com.sap.engine.services.webservices.jaxrpc.exceptions.InvalidResponseCodeException: Invalid Response Code: (407) Proxy authorization required
please note
1. i am trying to test this on my local sap j2ee server, on my workstation. i am not deploying this as of yet to the portal.
2. i do have access to r/3.
3. the r/3 application server is in our corporate intranet, and therefore excluded from being looked up by our proxy.
4. our proxy DOES require a username and password. i added my user name and password to the webservice container section of the visual administrator, and excluded the r/3 server from the proxy list.
what am i missing?

Zafar,
Check the endpoint in generated WSDL. Probably there is a host name that is not in "exclude list" for proxy settings (like IP vs host name, or FQDN vs short host name).
