生成静态页面问题

我用下面这个代码：

import java.io.ByteArrayOutputStream;

import java.io.FileOutputStream;

import java.io.IOException;

import java.io.OutputStreamWriter;

import java.io.PrintWriter; 

  



import javax.servlet.RequestDispatcher;

import javax.servlet.ServletContext;

import javax.servlet.ServletException;

import javax.servlet.ServletOutputStream;

import javax.servlet.http.HttpServlet;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import javax.servlet.http.HttpServletResponseWrapper; 



public class toHtml extends HttpServlet

{ 



public void service(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException

{

String url="";

String name="";



ServletContext sc = getServletContext();



String file_name=request.getParameter("file_name");//你要访问的jsp文件,如index.jsp

//则你访问这个servlet时加参数.如http://localhost/toHtml?file_name=index 



url = "/"+file_name+".jsp";//这是你要生成HTML的jsp文件,如

//http://localhost/index.jsp的执行结果. 



name="/home/resin/resin-2.1.6/doc/"+file_name+".htm";//这是生成的html文件名,如index.htm.



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(); 

FileOutputStream fos = new FileOutputStream(name); //把jsp输出的内容写到xxx.htm

os.writeTo(fos);

fos.close();

PrintWriter out=response.getWriter();

out.print("<p align=center><font size=3 color=red>首页已经成功生成！Andrew</font></p>");

}

}
