And the servlet file is ::

package sp;

import java.io.;
*import javax.servlet.;
*import java.sql.;
*import javax.naming.;
*import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.sql.DataSource;

public class servlet2 extends HttpServlet {

protected void processRequest(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html;charset=UTF-8");
PrintWriter out = response.getWriter();
try {
out.println("<html>");
out.println("<head>");
out.println("<title>Servlet servlet2</title>");
out.println("</head>");
out.println("<body>");
try{
DataSource ds = null;
Context myc = new InitialContext();
ds = (DataSource) myc.lookup("jdbc/myDatasource");
Connection con = ds.getConnection();
Statement stmt = con.createStatement();
ResultSet rs = stmt.executeQuery("Select prod_id from mytable1");
while(rs.next()){
out.println(rs.getString(1)"
");
}
}
catch(Exception e){
out.println("THE ERROR IS : " e);
}
out.println("</body>");
out.println("</html>");

} finally {
out.close();
}
}
--------------------------------------------
also i hv copied these files to the lib folder of glassfish server v2 and then set the class suffix as
$(com.sun.aas.installRoot)/lib/msbase.jar
$(com.sun.aas.installRoot)/lib/msutil.jar
$(com.sun.aas.installRoot)/lib/mssqlserver.jar.
in the glassfish server admin console
