Hi,
Is it possible to detect the actual error reason in form based loging?

For example, user does not exist, password mismatch...

Now before someone says well you wouldn't want to be telling the user why they failed would you? this is just for some logging etc.

Cheers

Luke,
What tool is doing login on your behalf? If you were doing it yourself, you would definitely know. If your app server or a single sign in tool is doing login, it would depend on the tool.

I am using websphere.

Basically, I would like to know some more information. For example the HTTP status code is it 401, 402, 403 etc.?

many thanks.
 
It is sorta covered in the JavaRanch Style Guide.
