getting AbstractMethodError when attempting to implement JavaCompiler interface

[James Puthukattukaran <ja...@symantec.com>]

I have defined my own class (IJC) that implements the JavaCompiler
interface and am using it with Websphere 5.0.
The IJC class is used instead of the default Java compiler when the JSP
engines loads it (defined jspCompilerPlugin in the ibm-ext.xml file).
 
When it attempts to load the class, it fails giving the following stack
trace.

(only posted the relevant part of the stack trace). Where is setVerbose
defined? I can't seem to find it in the javadoc pages for JavaCompiler.
 
thanks,
