## Class BSFJavaScriptEngine

- java.lang.Object
- - org.apache.bsf.util.BSFEngineImpl
  - - org.apache.jmeter.util.BSFJavaScriptEngine

- All Implemented Interfaces:
    PropertyChangeListener, EventListener, org.apache.bsf.BSFEngine

      public class BSFJavaScriptEngine
      extends org.apache.bsf.util.BSFEngineImpl

  This is the interface to Netscape's Rhino (JavaScript) from the Bean Scripting Framework.

  The original version of this code was first written by Adam Peller for use in LotusXSL. Sanjiva took his code and adapted it for BSF. Modified for JMeter to fix bug BSF-22.
