JSP说类是抽象的，看起来并不像

Question

我有一个用Java编写的Web服务TaskListWS，我正在使用NetBeans 8.0.2

我已经创建了wsdl并通过测试Web服务功能对其进行了测试。

然后我做了一个＆＃34;生成并复制WSDL＆＃34;给我的客户sc_demo。

JSP文件现在都有错误说

com.shoulderscorp.services.TaskListWS service = new com.shoulderscorp.services.TaskListWS();
com.shoulderscorp.services.TaskListWS port = service.getTaskListWSPort();

出错，因为TaskListWS是抽象的，无法实例化。该类不是抽象的，并且类中没有抽象方法。

这是被调用的方法：

@WebService(serviceName = "TaskListWS")
public class TaskListWS {

    private boolean inited = false;

    private QueueManager qm = new QueueManager();

    private static final String[] statusValues = {"Active", "Completed", "Waiting", "Damaged"};

    /**
     * Web service operation
     */
    @WebMethod(operationName = "getTaskListForUser")
    public String getTaskListForUser(@WebParam(name = "userToken") String userToken) {
...
}

wsdl文件包含：

我不确定为什么会这样或者如何修复它。
