servlet for radio buttons

[Shweta Sivashankar]

I have a webpage, with radio buttons in them. There are 4 possible choices, only one of which is the right answer. this right answer is stored in a MySql database. Does anyone know the code to put in the servlet to check whether the radio button checked by the user corresponds to the right answer in the databse? The connection is fine, when I run the servlet I get this error:

Sorry, your answer is incorrect. The correct answer wascom.mysql.jdbc.ResultSet@93d6bc.

thanks
