JBuilder 3.5 Minor help

When I compile it in JBuilder it doesn't seem to want to access the getBounds() function (do they even call them functions in Java? I'm an Old C++ porgrammer). I figure this is because JBuilder doesn't actually use the HTML file you create for testing. Is there anyway I can make it run the HTML file from in JBuilder?

They are usually called methods.
Right click on the html file and click run.
