Acredito que o erro esta neste if porem nao tenho ideia de resolver
esse if mostra com um icone na tela de login se o banco de dados esta ativo ou nao

if (conexao != null) {
lblStatus.setIcon(new javax.swing.ImageIcon(getClass().getResource("/icones/bancoOK.png")));
} else {
lblStatus.setIcon(new javax.swing.ImageIcon(getClass().getResource("/icones/bdError.png")));
}
