Section B.1. Running BeanShell


B.1. Running BeanShell

All you need to run BeanShell is the Java runtime system (Version 1.1 or greater) and the bsh JAR file. Under Windows, you can launch a graphical desktop for BeanShell by simply double-clicking the JAR file icon. More generally, you can add the JAR to your classpath:

     Unix:     export CLASSPATH=$CLASSPATH:bsh.jar     Windows:  set classpath %classpath%;bsh.jar

You can then run BeanShell interactively in either a GUI or command-line mode:

     java bsh.Console       // run the graphical desktop     java bsh.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:

     % java bsh.Interpreter myfile.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.
