Java Bean

I get more and more questions from persons who want to add PJC (beans) to their Oracle Forms Application. But what would be a nice component to add to a Oracle Forms applications?

There has been a PJC-competition which resolved in a couple of nice java components? But what would be the bean you are all waiting for? Please let me know.

One suggestion is a java component who can capture a stream from a webcam. But I assume there are lots and lots more suggestions.
