无法将Java Web Service部署到Glassfish

Question

我正在尝试将简单的Web服务部署到Glassfish。 这是Web服务类：

import com.dv.testrunner.extended.Task;
import com.medallion.etl.exception.StepExecutionException;
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.jws.WebMethod;
import javax.jws.WebParam;
import javax.jws.WebService;

/**
 *
 * @author dvargo
 */
@WebService(serviceName = "Execute")
public class Execute
{
    /**
     * Web service operation
     */
    @WebMethod(operationName = "executeTask")
    public boolean executeTask(@WebParam(name = "task") Task task)
    {
        boolean setUp = task.setUp();
        boolean execute;
        try
        {
            execute = task.execute();
        }
        catch (StepExecutionException ex)
        {
            Logger.getLogger(Execute.class.getName()).log(Level.SEVERE, null, ex);
            return false;
        }
        return setUp && execute;
    }
}

任务是一个简单的界面。 这是界面：

package com.dv.testrunner.extended;

import com.medallion.etl.exception.StepExecutionException;

/**
 *
 * @author dvargo
 */
public interface Task
{

    public boolean execute() throws StepExecutionException;

    public boolean setUp();

}

当我尝试通过Netbeans部署Web服务时，出现以下错误：

是否有人对正在发生的事情以及如何解决它有任何想法？ 是我不能使用Task作为参数吗？

Answer 1

JAX-WS不允许将接口用作方法参数。 尝试用一个类替换Task。

Answer 2

不仅JAX-WS不允许使用接口，在您的情况下甚至都没有意义。 您将如何指定任务应该执行的工作？ 您需要一个具体的类作为参数，并且该类需要使用@XmlRootElement进行注释。 如果您希望端点支持不同的任务，则需要使用不同的名称进行更多的操作才能实现。
