Access web service from tool area

Question

Hi,
I want to edit the tool Area iView to invoke an external web services.
I created a tool Area iView to be customized by importing “com.sap.portal.navigation.toolarea.par.bak” file from the NW2004s and create new portal project.
I know how to edit add or remove any part from the tool area iview
But how I can access the web service proxy? or what is the best way to implement that.

Answer 1

Stumbled into a small problem:
I have this method in my web service:
@WebMethod(operationName = "test")
    public Integer test(@WebParam(name = "number")
    int number) {
    return number;
}My client looks like this
public static void main(String[] args) {
    try {
         String BODY_NAMESPACE_VALUE = /*namespace url*/;
         QName port = new QName(/*Service name*/);
         ServiceFactory factory = ServiceFactory.newInstance();
         Service service = factory.createService(new QName(/*Service name*/));
         Call call = service.createCall(port);
         call.setTargetEndpointAddress(/*WSDL location*/);
         call.setReturnType(XMLType.XSD_INT);
         call.setOperationName(new QName(BODY_NAMESPACE_VALUE, "test"));
         call.addParameter("number", XMLType.XSD_INT, ParameterMode.IN);
         Integer[] i = new Integer[1];
         i[0] = new Integer(20);
         System.out.println("test :"+call.invoke(i));
    } catch (Exception ex) {
        ex.printStackTrace();
} I get return values ok from the web service in my java client since I tried getting a constant from the web service. However, in the case above I am trying to send 20 from the client to the web service and receive it back. However I am receiving 0. Does anyone know why sending parameters from client to web service is not working?
Thanks and regards,
