APEX

Hi ,

I created one new application in apex with theme 17 and using application express authentication.

Problem if i entered wrong username it is throwing error like no data found.

If I entered valid username and invalid password it is trowing error like invalid login credentials.

Is there any way to send proper message in these two cases like Please enter valid user name and Please enter valid password.

I am working apex 4.1

db is 11g


Thanks

Sagar.
