Pl see : down given is my code for uploading a file
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
import com.oreilly.servlet.*;
import java.util.*;
public class Upload extends HttpServlet
{
public void doPost(HttpServletRequest req,HttpServletResponse res)throws ServletException,IOException
{

res.setContentType("text/html");
PrintWriter out = res.getWriter();
try{
System.out.println(req.getHeader());
MultipartRequest multi =
new MultipartRequest req,"/temp",1024*1024);
out.println("<html>");
out.println("<head><title>UploadTest</head></title>");
out.println("<body>");
out.println("<h1>upLoadTest</h1>");
out.println("<pre>");
Enumeration params = multi.getParameterNames();
while (params.hasMoreElements())
{
String name = (String)params.nextElement();
String value = multi.getParameter(name);
out.println( name + " = " + value);
}
out.println("</pre>");
out.println("<h3> files : </h3>");
out.println("<pre>");
Enumeration files = multi.getFileNames();
while (files.hasMoreElements())
{
String name = (String)files.nextElement();
String filename = multi.getFilesystemName(name);
String type = multi.getContentType(name);
File f = multi.getFile(name);
out.println("name : " + name);
out.println("file name : "+ filename);
out.println("type : "+type);
if (f!=null){
out.println("length : " +f.length());
out.println();
}
out.println("</pre>");
}
}
catch(Exception e)
{
out.println("<pre>");
System.out.println(e);
e.printStackTrace(out);
out.println("</pre>");
}
out.println("</body> </html>");
}
}
