以下是java源码 ReturnTo.java package examples;
import java.io.*;
import java.util.*;
import javax.Servlet.*;
import javax.servlet.http.*;
/*
自动转向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>");
  }
}  应用test.jsp <%@ page contentType="text/HTML;charset=GBK"%>
<jsp:useBean id="we" scope="page" class="com.china3cts.common.ReturnTo" />
<%
   String Msg="自动转向中....";
   String Url="http://www.java3z.com";
   we.setMsg(Msg);
   we.setRurl(Url);
   we.setIsA(true);
   we.go(response);
%> 注释说明: 1:保存文件位置 ReturnTo.class ===>web-inf/classes/examples/ test.jsp 任意位置 2,写这个主要是不想页面上出现太多的javascript代码:) 纯粹无聊. 3,测试在tomcat + jdk1.5 + win2k3 下通过.
