如何找到java ClassCastException发生的位置(How to find where the java ClassCastException is happening)

只是想知道是否有人可以从下面的代码中看到为什么我得到异常“java.lang.ClassCastException”。

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

我知道异常意味着什么，但我不知道如何追踪它。

// 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

谢谢亚历克西斯

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
