By enclosing all of your logic in a single try-catch block, any error will 
cause the catch to be called. This may leave the connection to the database. 
You should include a finally to remedy that.


import com.ibm.as400.access.*;
import java.sql.*;

public class DisplayAudit {
 public static void main(java.lang.String[] args) {
  Connection conn = null;
  try {
   Class.forName("com.ibm.as400.access.AS400JDBCDriver");
   conn = DriverManager.getConnection("jdbc:as400://KITS01");
   Statement stmt = conn.createStatement();
   ResultSet rs = stmt.executeQuery("select * from " +
    "kleinr.audit");
   while(rs.next()) {
    java.math.BigDecimal custID = rs.getBigDecimal("CDENTL", 0);
    String custName = rs.getString("CDJOB");
    String custStreet = rs.getString("CDUSPF");
    String custCity = rs.getString("CDETYP");
    System.out.println("Customer ID     : " + custID);
    System.out.println("Customer Name   : " + custName);
    System.out.println("Customer Street : " + custStreet);
    System.out.println("Customer City   : " + custCity);
   }
   rs.close();
  }
  catch (Exception e) {
   System.out.println("Exception: " + e);
   e.printStackTrace();
  }
  finally {
   if (conn != null) {
     conn.close();
   }
  }
 }
}
