最近在学习Java EE6 ，使用NetBean 6.8和GlassFish v3进行学习开发。对Java EE6 的感觉很不错，它屏蔽了很多细节方面的东东，方便了开发，尤其是Annotation（注解）解脱了配置XML的烦恼。我不想说Annotation多么多么好，所有的技术都有其问题域，都有其触及不到的地方，Java ,.Net 也是如此。
1.开发JAX-WS Web Service 服务端.
a.使用NetBean 新建一个Web Application
b. 新建一个Service
package server
import javax.jws.WebService;
import javax.jws.webMethod;
@WebService
public class Hello {
private String message = new String("Hello, ");
public void Hello() {
}
@WebMethod
public String sayHello(String name) {
return message + name + ".";
}
}
服务建完后，可以用NetBean提供的测试功能对其进行测试，说实在的这个功能很实用。
测试服务地址：http://localhost:8080/helloservice/HelloService?Tester
WSDL地址:http://localhost:8080/helloservice/HelloService?WSDL
2. 开发JAX-WS Web Service 客户端
a.用NetBean新建Web Application
b.新建Web Service 客户端
c.新建Servlet
package client;
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.xml.ws.WebServiceRef;
import ws.Hello;
import ws.HelloService;
/**
*
* @author rywei
*/
@WebServlet(name="WsClient", urlPatterns={"/WsClient"})
public class WsClient extends HttpServlet {
@WebServiceRef(wsdlLocation="WEB-INF/wsdl/localhost_8080/StudyWeb/HelloService.wsdl")
private HelloService helloservice;
/**
* Processes requests for both HTTP <code>GET</code> and <code>POST</code> methods.
* @param request servlet request
* @param response servlet response
* @throws ServletException if a servlet-specific error occurs
* @throws IOException if an I/O error occurs
*/
protected void processRequest(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html;charset=UTF-8");
String s="";
if (helloservice!=null){
Hello hello=helloservice.getHelloPort();
s = hello.sayHello("RenYan Wei");
}
PrintWriter out = response.getWriter();
try {
out.println("<html>");
out.println("<head>");
out.println("<title>Servlet WsClient</title>");
out.println("</head>");
out.println("<body>");
out.println("<h1>Servlet WsClient at " + request.getContextPath () + "</h1>");
out.println("<br>");
out.println(s);
out.println("</body>");
out.println("</html>");
} finally {
out.close();
}
}
// <editor-fold defaultstate="collapsed" desc="HttpServlet methods. Click on the + sign on the left to edit the code.">
/**
* Handles the HTTP <code>GET</code> method.
* @param request servlet request
* @param response servlet response
* @throws ServletException if a servlet-specific error occurs
* @throws IOException if an I/O error occurs
*/
@Override
protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
processRequest(request, response);
}
/**
* Handles the HTTP <code>POST</code> method.
* @param request servlet request
* @param response servlet response
* @throws ServletException if a servlet-specific error occurs
* @throws IOException if an I/O error occurs
*/
@Override
protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
processRequest(request, response);
}
/**
* Returns a short description of the servlet.
* @return a String containing servlet description
*/
@Override
public String getServletInfo() {
return "Short description";
}// </editor-fold>
}
在浏览器内打开http://localhost:8080/WsClient/HelloServlet 进行测试
让人头疼的事是GlassFish v3 内不能在同一个Web Application 同时有客户端与服务端。我建了两个工程，A工程
是服务端，B工程是客户端，这时能正常运行，当我在B工程里建个服务端，要在A工程内进行调用时，就会产生错误，我找了很长时间也不知道是怎么回事，望各位大侠知道的话，欢迎分享，谢谢。
错误如下：
信息: Loading application WSWeb at /WSWeb
信息: WSWeb was successfully deployed in 2,656 milliseconds.
