如何找到java ClassCastException发生的位置

只是想知道是否有人能理解为什么我从下面的代码中得到异常“java.lang.ClassCastException”

    // 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

RISService、RisPortType是我从WSDL文件获得的库，然后使用wsimport生成.java文件

    // 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

我知道异常意味着什么，但我只是不知道如何追踪它

    // 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

谢谢

我打赌您的密码将以

char[]

的形式返回，jaxws需要一个字符串。

在我的例子中

    // 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

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"));

objectport=service.getPort（qname，c）；
WSBindingProvider bp=（WSBindingProvider）端口；
//手动设置连接超时，因为我们在IT测试期间似乎遇到了这些超时
Map requestContext=bp.getRequestContext（）；
put（BindingProviderProperties.REQUEST_TIMEOUT，env.getProperty（“TIMEOUT”））；
put（BindingProviderProperties.CONNECT_TIMEOUT，env.getProperty（“TIMEOUT”））；

正如您所看到的，requestContext.put（）接受一个字符串和一个对象，您认为放置一个字符串超时会起作用，但不，java ws需要一个int。。

这是一个巨大的陷阱。

DOH！。。。真不敢相信我竟然忘了！谢谢，这就解决了。
