Error while executing Servlet. java.lang. (Error in loading Specific Driver

Question

Hi all,
I am getting the following error while running the servlet.
Error:
java.lang.ClassNotFoundException: com.microsoft.jdbc.sqlserver.SQLServerDriver,
The above error arise while I try to access a data from the database table using servlet through browser, but the same driver works well in jdbc program(jdbc alone).
Here is how I am load the driver:
Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");
con=DriverManager.getConnection("jdbc:microsoft:sqlserver://NODE1:1433","**","**");
con.setCatalog("senthil");
Here is my software specification:
Tomcat5.5.26,
MS SQL Server 2000 Driver.
Looking forward to your reply,
Thanks in advance,
Senthil.

Answer 1

Hi,
Thanks for your reply.
Yes, I am using the Eclipse IDE, and it doesn't shows any error while I save the servlet source file.
Please find the below source code:
*1. JDBC program to retrive data from the database table: No issue works well.*
The below source code works well and I used it to retrive the data from the database table using the jdbc.Here there is no problem, the source code works well.
package pak;
import java.sql.*;
import java.io.*;
class UserDataDemo
     public static void main(String args[])
          Connection con;
          ResultSet result;
          try
               Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");
               con=DriverManager.getConnection("jdbc:microsoft:sqlserver://NODE1:1433","user_name","password");
               con.setCatalog("datadase_name");
               Statement stat=con.createStatement();
               result=stat.executeQuery("select * from table_name");
               while(result.next())
                    System.out.println("**************************************");
                    System.out.println("Name :"+result.getString(1));
                    System.out.println("Company :"+result.getString(2));
                    System.out.println("Position:"+result.getString(3));
                    System.out.println("Emp Id :"+result.getInt(4));
                    System.out.println("Place :"+result.getString(5));
          catch(Exception e)
               System.out.println(e);
*2.Issue: Servlet program used to retrive data from the data base table through jdbc:*
Here I am getting above said error : java.lang.ClassNotFoundException: com.microsoft.jdbc.sqlserver.SQLServerDriver
Please note, here I dosen't get any compile time error(i.e, eclipse ide doesn't shows any error while saving this file).
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import java.sql.*;
public class ServletTest extends HttpServlet
     String name;
     ResultSet result;
     PrintWriter pw;
     public void doGet(HttpServletRequest req,HttpServletResponse res)throws ServletException,IOException
          Connection con;
          try
               res.setContentType("text/html");
               pw=res.getWriter();
               Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");
               con=DriverManager.getConnection("jdbc:microsoft:sqlserver://NODE1:1433","user_name","password");
               con.setCatalog("database_name");
               Statement stat=con.createStatement();
               result=stat.executeQuery("select * from table_name");
               while(result.next())
                    pw.println(result.getString(1));
          catch(Exception e)
               pw.println(e);
Also please note, I have no problem in running the servlet alone.
Looking forward to your reply,
Thanks,
Senthil.
