Running BeanShell
All you need to run BeanShell is the Java runtime system (version 1.1 or greater) and the bsh JAR file. Under Mac OS X and Windows, you can launch a graphical desktop for BeanShell by simply double-clicking the JAR file. More generally, you can add the JAR to your classpath:
Unix:exportCLASSPATH=$CLASSPATH:bsh.jarWindows:setclasspath%classpath%;bsh.jar
You can then run BeanShell interactively in either a GUI or command-line mode:
javabsh.Console// run the graphical desktopjavabsh.Interpreter// run as text-only on the command line
Running BeanShell with the GUI console brings up a simple, Swing-based desktop that allows you to open multiple shell windows with basic command history, line editing, and cut-and-paste capability. There are some other GUI tools available as well, including a simple text editor and class browser. Alternately, you can run BeanShell on the command line, in text-only mode.
You can run BeanShell scripts from files, like so:
%javabsh.Interpretermyfile.bsh
Within some versions of the NetBeans and Sun Java Studio IDEs, you can create BeanShell script files using the New File wizard or run any file with a .bsh extension just as you would execute Java code.
