Java EE (Java Enterprise Edition) General Discussion

I'm trying to do some research on this issue, but most of what I find is very old. Can anybody provide any insight on why JSP might be better than ColdFusion? The primary focus is connecting to databases and producing web pages. Supposedly CF is awesome at rapid development of these types of pages. Is JSP really any more difficult? Is JSP more maintainable since developers don't need to learn a proprietary tag library? Any pros/cons for using one technology vs the other would be greatly appreciated.
