Hello,

I have a page .Xhtml, which contains a list of choices (Oracle, Teradata), I want :

1 - If the user chooses Oracle will display the fields (host, port, user, password, basename) will fill it, and calls the method connect in class ManagedBeanO.

2 - If the user selects Teradata, there will be just the fields (host, user, password) to complete, and calls the method connect in class ManagedBeanT to connect.
