I am working on a desktop based application that is like drop box, I have a function downloadFile(long fileId) that download file for me from web, desktop side of the application is in java where web service is written in .Net

I have generated WS client using netbeans

The issue is: Some times it happens that downloadFile(long fileId) function get stuck,

What ever the reason behind it, I want if web service function does not give any response till a given time I snatch the control back from that function and generate a new call after some time. Is it possible using java?

EDIT I think that it could be done if can set the request time out of the web service but i don't have idea how to set time out in the client generated by netbeans

In the class FileUpload that is root class of web service(Generated by netBeans) there were some constructors of the class and function of the super class, one of them i was using to create SOAP object. That was looking like 

@WebEndpoint(name = "FileUploadSoap")
public FileUploadSoap getFileUploadSoap() {
   return super.getPort(new QName("http://svc.qleapahead.com/", 
    "FileUploadSoap"), FileUploadSoap.class);
    }

in this function i made some modifications in order to set time out parameter and this became like 

@WebEndpoint(name = "FileUploadSoap")
public FileUploadSoap getFileUploadSoap() {
    FileUploadSoap fileUploadSoap = super.getPort(new QName(
            "http://svc.qleapahead.com/", "FileUploadSoap"),
            FileUploadSoap.class);
    ((BindingProvider) fileUploadSoap).getRequestContext().put(
            "com.sun.xml.internal.ws.request.timeout", 1000 * 2 * 60);
    return fileUploadSoap;
}

and problem solved...

in short this statement helped me a lot

((BindingProvider) fileUploadSoap).getRequestContext().put(
                "com.sun.xml.internal.ws.request.timeout", 1000 * 2 * 60);

Depending on the framework you use for calling the webservice, there will be some way of setting a readTimeout causing the call to fail with some kind of exception.

    my WS is SOAP based and used netbeans to generate client to consume web service, can you explain how to set readTimeOut ??? – NoNaMe Dec 14 '12 at 13:26

    `readTimeOut` is a property on the HTTP connection. I'm not familiar with Netbeans, but perhaps this thread is helpful: http://stackoverflow.com/questions/9536616/setting-socket-read-timeout-with-javax-xml-soap-soapconnection – Anders R. Bystrup Dec 14 '12 at 13:32
