Web, Wap & iMode Java J2SE/J2EE Lightweight Framework and Tools
MoioChart is a Java library to draw function plots, bar graphs, pie graphs, etc. It can work with Swing, SWT, and SuperWaba (an open source Java-like environment for handhelds and smartphones).
SWCollections is a port of the popular java.util classes to the SuperWaba platform. SuperWaba doesn't have Collections support by itself, but you will be able to use an ArrayList or a TreeMap as usual with this library.
