<h1>Rhino and BSF</h1>
<h2>What is BSF?</h2>
<p>
The <a href="http://jakarta.apache.org/bsf/">Bean
Scripting Framework</a> (or BSF) was originally developed by IBM and now
published as open source as a project at the Apache Software Foundation. It provides a framework for using a number of
scripting languages with Java. Rhino is one of the supported languages.
</p>
<p>This framework has been embedded in a number of open source projects,
including the XSL processor <a href="http://xml.apache.org/xalan-j/">Xalan</a>
and the XML/Java build tool <a href="http://ant.apache.org/">Ant</a>.
See <a href="http://xml.apache.org/xalan-j/extensions.html">Xalan-Java
Extensions</a> for more information on adding JavaScript to XSL and the description of the optional Script task in the
<a href="http://ant.apache.org/manual/">Apache Ant Manual</a> for using scripting in Ant build files.
</p>
<h2 id="bsf-issue">Using BSF with Rhino</h2>
<p>If you use BSF 2.3.0 Release candidate 1 (released 2002-11-12) or earlier versions, you have to use Rhino 1.5R2 or Rhino 1.5R3 (see Rhino <a href="download.html">download</a> page).
</p>
<p>
If you want to use later releases of Rhino, then as of time of writing, 2004-11-29, you have to either build BSF from <a href="http://jakarta.apache.org/site/cvsindex.html">Apache's CVS</a> or use pre-built binaries since BSF project has not yet released an official version incorporating all the necessary changes to work with Rhino 1.5R4 or later.
</p>
<p>You may find a pre-built BSF incorporating these changes (and all that will
make up the new version 2.4.0) in the BSF4Rexx-package at <a
href="http://wi.wu-wien.ac.at/rgf/rexx/bsf4rexx/current/">http://wi.wu-wien.ac.at/rgf/rexx/bsf4rexx/current/</a>.
(BSF4Rexx
allows Java to easily invoke <a href="http://www.RexxLA.org>">REXX</a> and <a
href="http://www.ooRexx.org">ooRexx (Open Object Rexx)</a> scripts. For ooRexx
the BSF4Rexx support allows ooRexx programmers
to use all Java classes and Java objects, as if they were (weakly) typed ooRexx
classes and objects. In addition it allows to script/automate <a
href="http://www.OpenOffice.org">OpenOffice.org</a> in a platform independent
manner using its Java-APIs with the help of BSF.)
</p>
<h2 id="bsf-new-RC2">New BSF version 2.4.0 pending</h2>
<p>As of 2006-09-16 the BSF team is about to release version 2.4.0, which
resolves this issue with the new distribution.
Release candidate 2 (RC2) will be voted upon for release for the beginning of
October 2006. News (and an updated WWW-site)
will be found at <a
href="http://jakarta.apache.org/bsf/">http://jakarta.apache.org/bsf/</a>.
