I want to write a very simple GUI asking user to input his/her database uid and pwd. If the login is accepted or rejected, they will see the corresponding pages. Just wondering how to check if the uid/pwd for database is correct ? just try to build a database Connection using the GUI's input uid/pwd ? and if there is no SQLException then it is ok, or it fails ? But it seems SQLException can be caused by other database problem other than incorrect uid/pwd... How to exactly check if the uid/pwd is correct ?

thanks.

You will have to parse the exception I'm afraid. Each DB returns a consistant error message for an authentication failure, and SQLExceptions just repeat the content of that error. So for each DB you use this with you will need to watch out for the appropriate error message.
