throws ServletException, IOException {
request.setCharacterEncoding("utf-8");
response.setCharacterEncoding("utf-8");
response.setContentType("text/html");
if(request.getParameter("path")!=null && !"".equals(request.getParameter("path"))){
PrintWriter out = response.getWriter();
out.print(1123123131);
try{
File f = new File(request.getParameter("path"));
BufferedReader bufRead = new BufferedReader(new InputStreamReader(new FileInputStream(f)));
String str;
StringBuffer newstr = new StringBuffer("");
while((str = bufRead.readLine()) != null){
newstr.append(str+"<br>");
}
if(str!=null && str.length()>0)
{
Pattern p = Pattern.compile("<title>(.*?)</title>");
Matcher m = p.matcher(str);
while(m.find()){
System.out.println(m.group(1));
}
}
request.setAttribute("content", newstr);
}catch(IOException ioe) {ioe.printStackTrace();}
getServletConfig().getServletContext().getRequestDispatcher("/index.jsp").forward(request, response);
