Using the C++ APIs, BSF4ooRexx was developed as a bidirectional Java bridge based on the [[Bean Scripting Framework]]. This bridge enables ooRexx to communicate with Java objects and Java to interact with Rexx applications.<ref name=":10">{{Cite web |title=BSF4ooRexx |url=https://sourceforge.net/projects/bsf4oorexx/ |access-date=2024-11-10 |website=sourceforge.net|date=12 August 2024 }}</ref><ref name=":11">{{Cite news |last=Flatscher |first=Rony G. |date=2009 |title=The 2009 Edition of BSF4Rexx Part I |url=https://www.rexxla.org/presentations/2009/2009_orx20_BSF4Rexx_01.pdf |work=20th Rexx Language Symposium |publisher=RexxLA}}</ref> The bridge is realized by requiring the ooRexx package <code>BSF.CLS</code>, which defines public routines, classes and the environment symbol <code>.BSF4REXX</code>.<ref name=":11" /> Examples are provided for the use of Java classes in connection with [[Abstract Window Toolkit|AWT]], [[Swing (Java)|Swing]], [[JavaFX]], [[Java Database Connectivity|JDBC]], [[Java 2D]] and some others.<ref name=":10" /><syntaxhighlight lang="oorexx" style="background-color: #ffffff; !important" line="1">/* create Java object */

Based on BSF4ooRexx, interaction with [[Universal Network Objects]] (UNO), as used in [[OpenOffice.org|OpenOffice]] and [[LibreOffice]], is supported via the <code>UNO.CLS</code> package.<ref>{{Cite book |last=Waglechner |first=Christoph |url=https://wi.wu.ac.at/rgf/diplomarbeiten/BakkStuff/2009/20090621-Waglechner-Pitonyak-OOo/Waglechner_PitonyakNutshells.pdf |title=OpenOffice.org Automation Using ooRexx Scripting Language by means of Selected Nutshell Examples by Andrew Pitonyak |date=2009}}</ref> In addition, the <code>CLR.CLS</code> package together with [https://github.com/jni4net/jni4net Jini4Net] enables the use of the [[.NET Framework|.NET framework]].<ref>{{Cite book |last=Baginski |first=Adrian |url=https://wi.wu.ac.at/rgf/diplomarbeiten/BakkStuooR2016/20160723_Baginski-Adrian-ooRexx-Net-Cookbook.pdf |title=A .NET Cookbook Using ooRexx.NET |date=2016}}</ref> Communication with processes via the [[D-Bus]] [[middleware]] under Linux is possible using the <code>DBUS.CLS</code> package.<ref>{{Cite book |last=Lagler |first=Richard |url=https://wi.wu.ac.at/rgf/diplomarbeiten/Seminararbeiten/2015/20150220-Lagler-DBus.pdf |title=D-Bus Language Binding for ooRexx: An Introduction on Nutshell Examples |date=2015}}</ref>
