Bean Scripting Framework

Bean Scripting Framework (BSF) is a set of Java classes which provides scripting language support within Java applications, and access to Java objects and methods from scripting languages. BSF allows one to write JSPs in languages other than Java while providing access to the Java class library. In addition, BSF permits any Java application to be implemented in part (or dynamically extended) by a language that is embedded within it. This is achieved by providing an API that permits calling scripting language engines from within Java, as well as an object registry that exposes Java objects to these scripting language engines.

Supported Languages

BSF supports several scripting languages currently:

  • Javascript (using Rhino ECMAScript, from the Mozilla project)
  • Python (using either Jython or JPython)
  • Tcl (using Jacl)
  • NetRexx (an extension of the IBM REXX scripting language in Java)
  • XSLT Stylesheets (as a component of Apache XML project's Xalan and Xerces)

In addition, the following languages are supported with their own BSF engines:

Information on where to obtain scripting languages for use with BSF is available on the Related Projects page.
