JDBC-ODBC - Problem with Incorrect DSN

This section describes what will happen if you specified an incorrect DSN in the connection URL when using JDBC-ODBC Bridge.

It is very common that the DSN you entered in the connection URL is not defined or defined incorrectly. In this case, the JDBC-ODBC Bridge driver will raise an exception on the DriverManager.getConnection() method. Here is a sample showing what kind of exception you will get if the DSN is wrong:

/* OdbcConnectionWrongDsn.java
 - Copyright (c) 2015, HerongYang.com, All Rights Reserved.
 */
import java.sql.*;
public class OdbcConnectionWrongDsn {
  public static void main(String [] args) {
    Connection con = null;
    try {
      Class.forName("sun.jdbc.odbc.JdbcOdbcDriver") ;

// Connect with a wrong DSN
      con = DriverManager.getConnection("jdbc:odbc:HY_WRONG");
      System.out.println("Connection ok.");
      con.close();

    } catch (Exception e) {
      e.printStackTrace();
    }
  }
}

If you run this program, the Microsoft ODBC Driver Manager will return an error through the JDBC-ODBC Bridge driver:

C:\herong>\progra~1\java\jdk1.7.0_45\bin\javac 
   OdbcConnectionWrongDsn.java

C:\herong>\progra~1\java\jdk1.7.0_45\bin\java OdbcConnectionWrongDsn
