Interceptar exceções nos Drivers JDBC com Hibernate!!!

Olá! Caros Colegas!

Estou desenvolvendo um sistema.
Onde na tela de login, quero informar ao usuários os erros de acesso ao banco de dados como:
- Senha invalida
- Caminho ou endereco de servidor inválido
- Banco de dados não encontrado
- etc.

Contudo, esses erros geralmente são detectados nas exceções dos drivers JDBC, e não consigo capturá-las dentro do meu sistema.

Alguém tem alguma informação ou dica que pode me ajudar?
Alguém já conseguiu desenvolver algo parecido? como solucionou este problema?

Estou usando Swing/AWT, Hibernate 3.0, MySQL.

Desde já, agradeço a atenção de todos!!!

Vejam as saidas do console, para entenderem meu dilema:

Aqui, simulei uma falha de conexão com o Banco, portanto surge uma exceção no Driver JDBC do MySQL, conforme segue: com.mysql.jdbc.SQLError.createSQLException(SQLError.java:946), com a mensagem: java.sql.SQLException: Access denied for user: 'root@servidor' (Using password: YES)

Pois é exatamente essa exeção que desejo capturar.
Mesmo usando Try/Catch, essa exeção não é considerada e passa normalmente. O que pode ser? O que devo fazer?
