Manning formally released Eclipse in Action today. I glanced through it last night at Barnes & Noble, looks like a great book.

I learned about a feature called Java scrapbook pages, described in Chapter 2:

“… by virtue of its incremental compiler, you can enter arbitrary Java code into a scrapbook page and execute it—it doesn’t need to be in a class or a method.”

Scrapbook pages allow you to test code directly in Eclipse without having to create a class/project with a main() method and then run it from the command line. Pretty handy, reminds me of the demo I saw of Jython at JavaOne.
