JDBC I guess...
Maybe the difficulty is an indication that its not the right way to go...
For example if a user ever has to change their password... data is lost, or
a huge procedure.
Think about this... maybe its a good idea.
Remember that if you see the user name in a page.... it means they
authenticated.
So if the user gets to the code.... they had to come through the locked
door...
And if the user is going to get the data back through the browser... this
will probably work.
Invent a secret code.... A4H%BIGSECRETYtffguT etc etc.
Then HASH that say using MD5 with the User name....
That becomes your password.... and you lock and unlock the data with that.
Not terrific cryptography... but it will work and users can change their
passwords...
Could add some salt to that.... like the documents name.
Maybe.... good luck

You can't access the credential from HttpServletRequest object, it's not
made available as part of the Servlet spec.
Which realm implementation are you using?
