Null pointer exception occured in jdbc application

Question

Hi all,
I am trying to test a sample application in JDBC. While running it in eclipse IDE I am getting the below result.
CourseId:25 CourseName: SQL
CourseId:54 CourseName: XML
CourseId:61 CourseName: HTML
java.lang.NullPointerException
The code i am using is
try{
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
}catch(ClassNotFoundException e)
     System.out.println("Expected class not found");
     return;
try{
     Connection con=DriverManager.getConnection("jdbc:odbc:star"," "," ");
     Statement stmt=con.createStatement();
ResultSet rs=stmt.executeQuery("select * from ex1");
while(rs.next())
     System.out.println("CourseId:"+rs.getString(1)+" ourseName: "+rs.getString(2));
rs.close();
     stmt.close();
     con.close();
}catch(Exception e){
     System.out.print(e);
Please let me know what i am doing wrong. What should i do to eliminate that null pointer exception in the result.

Hi Newbee...
I jsut ran ur program on my system..
and it works fine on my system. No exception at
all...
..AmanWhich is why I asked about the data. If this were my program, I would look to see if the data is what I am expecting (no nulls, proper strings, etc).
Nice of you to actually run Newbee's program though...
