import java.io.*;
import java.util.*;
import javax.servlet.*;
import javax.servlet.http.*;
import java.lang.*;
import java.sql.*;
public class testepdf extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

String driver = "org.gjt.mm.mysql.Driver";
String url = "jdbc:mysql://sb/cmv?user=amd&&password=123";
String n1_ = "";

ResultSet rs = sta1.executeQuery(sql1);

response.setHeader("Content-disposition",
"inline; filename=\"Acta.pdf\"");
rs.next();
Blob blob = rs.getBlob(3);
if (blob != null)
{
int iLen = (int)blob.length();

So what actually happens when you try? Exceptions? Errors in log file? Work with us here - my crystal ball is in the shop.

There's a known problem with some browsers if you don't set the content-length header.
And you can't fake it - it has to be the true content-length.


Customer surveys are for companies who didn't pay proper attention to begin with.
