Password manager

I want to build an password manager application that can provide a servise similar to popular browers like opera and mozilla.

I want to know if there are any classes in java taht can help me in this.

Is there any way that the application can know when a user opens a webpage that asks for password so that it can prompt the user to save password for the same.....and that it can automaticaaly fill in the passwords in the required fields as and when required ?

Please help me out

regards
