Java IDEs tend to be expensive (in terms of ram). If this is a good size project, you may want to spend a little money on some ram.
As far as other IDEs: There is Eclipse (Open Source), JBuilder (Commercial with a free personal edition for non-commercial use), NetBeans (Open Source, This has been incorporated into Sun Studio. It might be more efficient to run just NetBeans.) Oracle has an app suite.
There are plenty of others too.
Myself, I use a text editor, the command line compiler, and Tomcat.
