以下是java源碼

ReturnTo.java

package examples;
import java.io.*;
import java.util.*;
import javax.servlet.*;
import javax.servlet.http.*;
/*
自動轉向javabean
*/
public class ReturnTo extends HttpServlet
{
 PRivate String Msg;
 private String Rurl;
 private boolean isA;

public void setMsg(String inMsg) {
  this.Msg=inMsg;
 }

 public void setRurl(String inRurl){
  this.Rurl=inRurl;
 }

 public void setIsA(boolean inisA){
  this.isA=inisA;
 }

 public String getMsg() {
  return this.Msg;
 }

 public String getRurl()  {
  return this.Rurl;
 }

 public boolean getIsA() {
  return this.isA;
 }

 public void go(HttpServletResponse response) throws IOException, ServletException {
  PrintWriter out = response.getWriter();
  out.print("<script language='Javascript'>");
  if (this.isA) {
   out.print("alert('"+ Msg + "!');");
  }
  out.print("location.href='"+Rurl+"';");
  out.print("</script>");
 }
}

應用test.jsp

<%@ page contentType="text/Html;charset=GBK"%>
<jsp:useBean id="we" scope="page" class="com.china3cts.common.ReturnTo" />
<%
  String Msg="自動轉向中....";
  String Url="http://www.java3z.com";
  we.setMsg(Msg);
  we.setRurl(Url);
  we.setIsA(true);
  we.go(response);
%>

注釋說明:

1:保存文件位置

ReturnTo.class ===>web-inf/classes/examples/

test.jsp 任意位置

2,寫這個主要是不想頁面上出現太多的javascript代碼:) 純粹無聊.

3,測試在tomcat + jdk1.5 + win2k3 下通過.
