RE: JDBC Error

"Function rejected by user exit program NW0001E in PSCOMMON"

Somebody in your company wrote and installed a user exit program that controls 
access to your AS/400 via the entry point that the JDBC driver uses. You should 
ask your co-workers and find out what you have to do.

I am trying to learn Java and how to access AS/400 data using JDBC and wrote a 
small program :
   
  import java.sql.*;                                            
public class MyDBRead{                                        
public static void main (String argv []){                    
  try {                                                                         
                                            
  Class.forName("com.ibm.as400.access.AS400JDBCDriver");      
  String sys = "TESTSYS1";                                       
  String user = "SIVAKUMARK";                                 
  String pass = "TEXAS1";                                    
  Connection con =  DriverManager.getConnection("jdbc:as400://"+sys,user,pass); 
  Statement stm = con.createStatement();                      
  ResultSet rs = stm.executeQuery("select FIELD1 from MYFILE");
  while(rs.next())  {                                     
    System.out.println(rs.getString(1)); }                                     
 rs.close();                             
 stm.close();                            
 con.close();   }                                      
 catch(Exception e) {                                       
  e.printStackTrace();  }                                        
 }      }
   
  The code compiled without any error. While trying to execute, its throwing 
following exceptions. Can someone tell what I am missing here?. Thanks for in 
advance.
