User authentication error with Proxy Java Calling web Service in XI

Question

Hello,
I have deploy a Web Service in SAP XI 3.0. within a SOAP sender adapter.
I have also created the Proxy Java Class to access the webservice in the Developer Studio and a Plain Java Class (only with a method main) which uses the proxy classes to consume the web service.
But when I launch the program a get the next error message:
java.rmi.RemoteException: Service call exception; nested exception is:
     com.sap.engine.services.webservices.jaxrpc.exceptions.InvalidResponseCodeException: Invalid Response Code: (401) Unauthorized.
     at com.everis.serviciosweb.xi.MI_OUT_STATUSBindingStub.MI_OUT_STATUS(MI_OUT_STATUSBindingStub.java:73)
     at com.everis.llamadas.invocacionWSStatus.main(invocacionWSStatus.java:76)
Caused by: com.sap.engine.services.webservices.jaxrpc.exceptions.InvalidResponseCodeException: Invalid Response Code: (401) Unauthorized.
     at com.sap.engine.services.webservices.jaxrpc.wsdl2java.soapbinding.MimeHttpBinding.handleResponseMessage
Where MI_OUT_STATUSBindingStub is my Stub Class.
I have tried to set USERNAME_PROPERTY and PASSWORD_PROPERTY at runtime from my Stub class to the values that I use to access SAP XI (Integration Repository & Integration Directory) but it still doesn't´t work.
Have anyone a solution?
Thanks.

Hi,
    finally I have fixed it.
The root of the problem was on the way that I proceed with the generation of wsdl in Integration Directory.
The second step in the wizard for generation of wsdl ask for a url to call the web service and gives you an option to complete the url automatic. I have use this option and it have proposed my an url of type http://<host>:<port>/sap/xi/engine?entry=.......
But the SOAP adapter call is in the form http://<host>:<port>/XISOAPAdapter/MessageServlet?channel=<party>:<business service>:<channel>
So using this type of url in the generation of wsld solves all the problems.

Antonio.
