out.println("href=")的问题
Exservlet写信息进数据库后,想有个连接返回到主页面(index.html),但是直接写out.println(   " <a   href= '/wy/index.html '> "   + "renturn "+   " </a> "   );好像不行,这样写的实际连接是http://127.0.0.1:8080/wy/servlet/index.html。怎么才能让连接到我想要的index.html?

×××××××××××××××××
目录结构是这样的:
C:\tomcat\webapps\wy\WEB-INF\classes\myservlet\Exservlet.class
                                          \index.html\
×××××××××××××××××
Exservlet文件
×××××××××××××××××
package   myservlet;  
import   java.io.*;
import   javax.servlet.ServletException;
import   javax.servlet.http.*;
import   java.sql.*;
import   com.jspdev.ch12.*;
import   com.jspdev.util.*;
public   class   ExServlet   extends   HttpServlet   {
public   void   doPost(HttpServletRequest   request,   HttpServletResponse   response)
throws   ServletException,   IOException   {
response.setContentType( "text/html;charset=gb2312 ");
PrintWriter   out   =   response.getWriter();
String   productId=request.getParameter( "productId ");
String   name=request.getParameter( "name ");
String   price=request.getParameter( "price ");
String   producer=request.getParameter( "producer ");
String   descn=request.getParameter( "description ");
String   categoryId=request.getParameter( "categoryId ");
//下面三步将界面的值传入到Bean中
Product   lbean=new   Product();
lbean.setProductId(productId);
lbean.setPrice(price);
lbean.setCategoryId(categoryId);
lbean.setName(name);
lbean.setDescription(descn);
lbean.setProducer(producer);
                //下面的这个步为连接数据库
try{
  //下面为写入数据库
  ProductBean   aduB=new   ProductBean();
  aduB.addProduct(lbean);
  out.println( " <html> ");
                  out.println( " <head> <title> addRecord </title> </head> ");
                  out.println( " <body> ");
                  out.println( " <p> Add   Success </p> ");
  out.println(   " <a   href= '/wy/index.html '> "   + "renturn "+   " </a> "   );
                  out.println( " </body> </html> ");
}catch(Exception   e){
e.printStackTrace();
}
}
public   void   destroy()   {
super.destroy();  
}
}


------解决方案--------------------
试试 out.println( " <a href=\ "/wy/index.html\ "> return </a> ");
