Prototype of a VERY simple instructional Java development environment. The environment has 3 panes: one editor for a source file, a message pane for compiler errors/warnings, and a shell pane for interacting with an interpreter. The environment requires (1) jikes (because of the ease of parsing its error/warning messages) (2) bsh (the BeanShell). It could be modified to use javac and jeva (or another interpreter), but I haven't done so, yet.
