    Problem in connecting with MSSQL Server 2000

    harpreetset Newbie

      I have installed jboss-3.2.1_tomcat-4.1.24 on my system. I want to connect to MS SQL Server 2000 database available on a different. I have changed mssql-ds.xml as follows


      as pasted it all\deploy directory.

      I got the following message on Server console which i think says that datasource deployed successfully.

      I am using the following program to access database through Datasource.

      import java.sql.*;
      import java.util.*;
      import javax.naming.*;

      public class simplesql {

      public static void main(String argv[])
      throws Exception
      java.sql.Connection conn = null;
      java.sql.Statement stmt = null;
      try {

      // ============== Make connection to database ==================
      // Obtain a Datasource connection from the WebLogic JNDI tree.
      Context ctx = null;

      // Put connection properties in to a hashtable.
      Hashtable props = new Hashtable();
      props.put(Context.PROVIDER_URL, "jnp://localhost:1099/");
      props.put("java.naming.rmi.security.manager", "yes");
      props.put(Context.URL_PKG_PREFIXES, "org.jboss.naming");

      // Get a context for the JNDI look up
      ctx = new InitialContext(props);
      System.out.println("got the context "+ctx);
      javax.sql.DataSource ds
      = (javax.sql.DataSource) ctx.lookup ("java:/mySQLServerPool");
      conn = ds.getConnection();
      System.out.println("Making connection...\n");

      // execute some SQL statements to demonstrate the connection.
      stmt = conn.createStatement();

      try {
      stmt.execute("drop table empdemo");
      System.out.println("Table empdemo dropped.");
      } catch (SQLException e) {
      System.out.println("Table empdemo doesn't need to be dropped.");

      stmt.execute("create table empdemo (empid int, name varchar(30), dept int)");
      System.out.println("Table empdemo created.");

      int numrows = stmt.executeUpdate("insert into empdemo values (0, 'John Smith', 12)");
      System.out.println("Number of rows inserted = " + numrows);

      numrows = stmt.executeUpdate("delete from empdemo where empid = 0");
      System.out.println("Number of rows deleted = " + numrows);
      } catch (Exception e) {
      System.out.println("Exception was thrown: " + e.getMessage());
      } finally {
      try {
      if (stmt != null)
      if (conn != null)
      } catch (SQLException sqle) {
      System.out.println("SQLException during close(): " + sqle.getMessage());


      The code is compiling perfectly, but while running i am getting the following error:

      Exception was thrown: mySQLServerPool not bound

      Please help me to solve this problem.
      Do i need to do more configuration for deploying Datastore on Jboss

          You cannot access a datasource from outside the JVM that is running JBoss. WebLogic provides a proxy implementation for datasources that allows remote clients to access a datasource by connecting to the WebLogic infrastructure that then connects to the datasource, as far as I understand their implementation.

          You can access JBoss datasources from EJBs or servlets/JSPs running in the embedded Jetty/Tomcat.
