高手近来看看啊，关于用servlet生成html页面的乱码问题!!!!
package   slt;

import   javax.servlet.*;
import   javax.servlet.http.*;
import   java.io.*;


public   class   ToHtml
extends   HttpServlet   {
private   static   final   String   CONTENT_TYPE   =   "text/html;   charset=GBK ";
FileOutputStream   fos   =null;
String   charset= "gbk ";

//Initialize   global   variables
public   void   init()   throws   ServletException   {
}


//Process   the   HTTP   Get   request
public   void   doGet(HttpServletRequest   request,   HttpServletResponse   response)   throws
ServletException,   IOException   {
response.setContentType(CONTENT_TYPE);
service(request,response);
}

//Process   the   HTTP   Post   request
public   void   doPost(HttpServletRequest   request,   HttpServletResponse   response)   throws
ServletException,   IOException   {
doGet(request,   response);
}
public   void   destroy()   {
}

public   void   service(HttpServletRequest   request,   HttpServletResponse   response)   throws
ServletException,   IOException   {
String   url   =   " ";
String   name   =   " ";
String   pName   =   " ";

ServletContext   sc   =   getServletContext();

url   =   "/indexbak125.jsp ";   //这是要生成HTML的jsp文件,如//http://localhost/index.jsp的执行结果.

name   =   "indexa.html ";   //这是生成的html文件名,如index.htm.
pName   =   "/usr/tomcat/webapps/ROOT/indexa.html ";   //生成html的完整路径


RequestDispatcher   rd   =   sc.getRequestDispatcher(url);

final   ByteArrayOutputStream   os   =   new   ByteArrayOutputStream();

final   ServletOutputStream   stream   =   new   ServletOutputStream()   {
public   void   write(byte[]   data,   int   offset,   int   length)   {
os.write(data,   offset,   length);
}

public   void   write(int   b)   throws   IOException   {
os.write(b);
}
};

final   PrintWriter   pw   =   new   PrintWriter(new   OutputStreamWriter(os));
HttpServletResponse   rep   =   new   HttpServletResponseWrapper(response)   {
public   ServletOutputStream   getOutputStream()   {
return   stream;
}

public   PrintWriter   getWriter()   {
return   pw;
}
};
rd.include(request,   rep);
pw.flush();
try
{
    fos   =   new   FileOutputStream(pName);
    fos.write(value.getBytes(charset));
    os.writeTo(fos);
    fos.close();
}
catch   (FileNotFoundException   e)
{
    e.printStackTrace();
}
catch   (UnsupportedEncodingException   e)
{
    e.printStackTrace();
}
catch   (IOException   e)
{
    e.printStackTrace();
}
response.sendRedirect(name);   //书写完毕后转向htm页面
}
}
这是我写的代码??
到底该怎么定义那个value才能解决生成的页面不是乱码并可以显示呢?
