call web service from java interface possible?

[timothy smith]

hello all!

i am new to web services and i would like to know whether it's possible to call a web service from a java user interface. all the examples i have met are creating bpel web service clients in jsp!(i am working in netbeans)
if anyone has a good tutorial or link with appropriate example in mind, please share it with me!
any help appreciated!

thank you very much for answering!

unfortunately it still hasn't answered my question. i am using netbeans and have already created the bpel project. what i need to do now is create the web service client. in all cases i have met in internet, the web client interacts with the web service via jsp page. what i want though is to create a web service client who is a java desktop application. does anyone know how to create such a web service client? thank you all!

If the BPEL has generated a WSDL then 3. WSDL2Java: Generate the Server-side Wrapper Code and Stubs For Easy Client Access shows you how to write a command line client with Axis 1.x. The code in a desktop application wouldn't be much different.

If course if you are using NetBeans with the Java 6 SDK then you should be using JAX-WS instead (I think it uses wscompile/wsimport or something like that instead of WSDL2Java).

yes i am using java 6 sdk. what i cant understand is the following: i create a java desktop application with one button only. i then create a web client for that project by pointing at the local wsdl file and finally when i am trying to add some line in the action which will be performed by the button i get warnings!

the code which i am adding is generated automatically by netbeans when i right click in the source and choose Web Service Client Resources --> Call Web Service Operation. the actual code is as follows :

     private void button1MouseClicked(java.awt.event.MouseEvent evt) {
    // TODO add your handling code here:
    
    
    try { // Call Web Service Operation
        testing.LoanRequestorService service = new testing.LoanRequestorService();
        testing.LoanRequestorPortType port = service.getLoanRequestorPort();
        // TODO initialize WS operation arguments here
        testing.ProcessApplication requestLoanMessage = null;
        // TODO process result here
        testing.ProcessApplicationResponse result = port.loanRequestorOperation(requestLoanMessage);
        System.out.println("Result = "+result);
    } catch (Exception ex) {
        // TODO handle custom exceptions here
    }
 
   
 
}

the error i get is cannot find symbol LoanRequestorService etc in package testing. Does anyone recognizes what i am doing wrong??

Find the generated .java files to determine whether these classes are actually inside the "testing" package.

Determine if the classpath in the execution environment actually includes the directory to which those .java files are compiled as .class files.

hmm i am not quit sure that i understand what you are saying.. but i am having another problem now, it isnt possible to make a new web client for my java desktop application, because i get a failed message after build! things are just getting worst!
