How to find where the java ClassCastException is happening

Question

Just wondering if anyone can see why i am getting the exception "java.lang.ClassCastException" from the code below.

RISService, RisPortType are lib that i got from a WSDL file and then use wsimport to generate the .java files

I know what the exception means but i am just not sure how to track it down.

    // Instantiate the wsimport generated SXML API Service client --
    RISService risportService = new RISService();
    RisPortType risportPort = risportService.getRisPort();

    // Set the URL, user, and password on the JAX-WS client
    String hostUrl = "https://10.1.1.1:8443/realtimeservice2/services/RISService";
    ((BindingProvider) risportPort).getRequestContext().put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY, hostUrl);
    ((BindingProvider) risportPort).getRequestContext().put(BindingProvider.USERNAME_PROPERTY, cucmDetails.getAxlUsername());
    ((BindingProvider) risportPort).getRequestContext().put(BindingProvider.PASSWORD_PROPERTY, cucmDetails.getAxlPassword());

    // create and populate the selectCmDevice request
    SelectCmDevice sxmlParams = new SelectCmDevice();
    CmSelectionCriteria criteria = new CmSelectionCriteria();
    long maxNum = 200;
    long modelNum = 255;
    ArrayOfSelectItem items = new ArrayOfSelectItem();

    //create a select item criteria to retrieve devices with names matching "SEP123412341234"
    SelectItem item = new SelectItem();
    item.setItem("SEP123412341234");
    items.getItem().add(item);

    //Search on all nodes
    criteria.setNodeName("Any");
    //get back max 200 phones. 9+ can get upto 1000
    criteria.setMaxReturnedDevices(maxNum);
    //get back phones only
    criteria.setDeviceClass("Phone");
    //255 means get back ALL phone models
    criteria.setModel(modelNum);
    //get back only Registered phones
    criteria.setStatus("Registered");
    //return results in order of name
    criteria.setSelectBy("Name");
    //array of phones to get results back for
    criteria.setSelectItems(items);
    sxmlParams.setCmSelectionCriteria(criteria);

    //make selectCmDevice request
    SelectCmDeviceReturn selectResponse = risportPort.selectCmDevice("",criteria); << This is where i get the exception outline below

Answer 1

I bet your password is being returned as a char[] and jaxws is expecting a String.

Answer 2

in my case

Object port = service.getPort(qname, c);
WSBindingProvider bp = (WSBindingProvider) port;
// Manually set connection timeouts as we seem to hit them during IT testing
Map<String, Object> requestContext = bp.getRequestContext();

requestContext.put(BindingProviderProperties.REQUEST_TIMEOUT, env.getProperty("timeout"));

requestContext.put(BindingProviderProperties.CONNECT_TIMEOUT, env.getProperty("timeout"));

as you can see requestContext.put() takes a String and a object, you thought putting a String timeout would work, but NO, java ws is expecting a int.. this is a massive catch ya.
