Binding in Prepared Statement is not working with Microsoft SQL Server JDBC

Question

I ran the following program with sqljdbc4.jar in the class path. There is data in the EMPLOYEE table for the employee name DEMO but the following program is not retrieving data for DEMO. When the same program was run with Merlia.jar in the class path, it was retrieving data for DEMO.
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
Connection con = DriverManager.getConnection("jdbc:sqlserver://SERVER23:5000;databaseName=TESTDB", "SYSADM", "SYSADM");
String sqlSele = "SELECT * FROM EMPLOYEE WHERE EMPNAME like ?" ;
PreparedStatement sts = con.prepareStatement(sqlSele);
sts.setString(1, "DEMO" );
ResultSet rs = sts.executeQuery();
while(rs.next())
System.out.println("driverConn.main()" + rs.toString());
catch(Exception e)
System.out.println(e);
e.printStackTrace();
Can someone help me out from this issue.

Answer 1

This is the program that I used for testing the behaviour of prepared statement with sqljdbc4.jar. Also included the code for Merlia.jar.
import java.sql.*;
public class driverConn {
     public static void main(String [] a)
          try{
          Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
          //Class.forName("com.inet.tds.TdsDriver");
          Connection con = DriverManager.getConnection("jdbc:sqlserver://SERVER23:5000;databaseName=TESTDB", "SYSADM", "SYSADM");
          //Connection con = DriverManager.getConnection("jdbc:inetdae7a:SERVER23:5000?database=TESTDB", "SYSADM", "SYSADM");
          String sqlSele = "SELECT * FROM EMPLOYEE WHERE EMPNAME like ?" ;
          //String sqlSele = "SELECT * FROM EMPLOYEE WHERE EMPNAME like ‘%DEMO%’”;
          PreparedStatement sts = con.prepareStatement(sqlSele);
          sts.setString(1, "DEMO" );
          //sts.setString(1, "%DEMO%" );          
          java.sql.ResultSet rs = sts.executeQuery();          
          while(rs.next())
               System.out.println("EMPNAME is " + rs.getString(“EMPNAME”) + “”);                    }
          catch(Exception e)
               System.out.println(e);
               e.printStackTrace();
