This is my java code...

import java.sql.*;
import javax.sql.*;

public class JDBCDemo{

public static void main(String args[]){
String dbtime;

//String dbUrl = "jdbc:jtds:sqlserver://";
//String dbClass = "com.mysql.jdbc.Driver";
String query = "Select * FROM EMPLOYEE_MASTER where EM_ID=356";

try {
System.out.println("Hello....");.....................This line is printing..
System.out.println("Hi..");..............It will not be printed.
Connection con = DriverManager.getConnection("jdbc:jtds:sqlserver://ktwo-19:1433;DatabaseName=KHRMS","sa", "Welcome12");
Statement stmt = con.createStatement();
ResultSet rs = stmt.executeQuery(query);

while ( {
String s = rs.getString("EM_USERNAME");


catch(ClassNotFoundException e) {

catch(SQLException e) {

} //end main

} //end class

It would be useful to see the stack trace of the exception. If nothing else, so we can see what class cannot be found.

the class net.sourceforge.jtds.jdbc.Driver could not be found, although you have jtds.jar file. Make sure the jar file is present in the classpath.

And could you please UseCodeTags next time? It will preserve whitespace and add syntax highlighting, making code easier to read.
