I am using Eclipse editor for developing this application and i am using sql server 2000 database.
i have create a servlet file.
here is the coding.
DatabaseGetConnection.java
`````````````````````````````````````````
import java.io.IOException;
import java.sql.Connection;
import java.sql.SQLException;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;
import javax.servlet.ServletConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletOutputStream;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.sql.DataSource;
public class DatabaseGetConnection extends javax.servlet.http.HttpServlet implements javax.servlet.Servlet {
private Connection con=null;
private DataSource ds=null;
public DatabaseGetConnection() throws ServletException {
super();               
public DatabaseGetConnection(final HttpServletRequest req, final HttpServletResponse res) throws ServletException, IOException {
this.doPost(req, res);          
public void init() throws ServletException {
try
final Context initContext = new InitialContext();
final Context envContext = (Context)initContext.lookup("java:/comp/env");
this.ds = (DataSource)initContext.lookup("jdbc/mySQLServer");
}catch(final NamingException ne)
ne.printStackTrace();
}catch(final Exception e)
e.printStackTrace();
public DataSource getDS()
System.out.println("Datasource method calling");
if (this.ds!=null)
System.out.println("Datasource not null");
}else
System.out.println("Datasource null");
return this.ds;
public Connection getCon()
try
this.con=this.getDS().getConnection();
if (this.con!=null)
System.out.println("Connection Successfull");
}catch(final SQLException se)
System.out.print("Connection Establishment Error : ");
se.printStackTrace();
return this.con;
I have configured server.xml. here is the configuration
server.xml
````````````````
<GlobalNamingResources>
<Resource name="jdbc/mySQLServer" global="jdbc/mySQLServer" auth="Container"
type="javax.sql.DataSource" factory="org.apache.tomcat.dbcp.dbcp.BasicDataSourceFactory" driverClassName="com.microsoft.jdbc.sqlserver.SQLServerDriver"
url="jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=forum;SelectMethod=cursor"
username="sa" password="sa" maxActive="20" maxIdle="10"
maxWait="-1"/>
</GlobalNamingResources>
here is the web.xml file
``````````````````````````````````
<resource-ref>
<res-ref-name>jdbc/mySQLServer</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
