Object Spy using Java

I am working on a project in Java where I should be able to launch a site and then recognize a browser Web Elements with a Mouse Over, like the Object Spy in QTP. The Elements that I hope to get are Name, Class Name, ID, Tagname, Linktext,Partial LinkText, CSS Xpath..etc..

I am kind of lost on how to bridge the Browser and the Application.Can anyone help?

Thank you in Advance.
