method on the class (this is merely a convenience, so you don't have to
implement
the interface in your script, you can simply just use the appropriate method
name).

Method m = findMethod(scriptClass, "beforePacks");
if (m != null) {
  m.invoke( scriptObject, new Object[] { idata, npacks, progressHandler } );

Yes, i agree on point #1.&nbsp; However, i&#39;m a little unsure of how we could force the compiler<br>to package up something like the groovy/ruby/beanshell jars into the installer if someone<br>used that installer listener.&nbsp; I guess a corresponding compiler listener might be the appropriate
<br>place, but i&#39;m not sure.&nbsp; I can very easily supply code which would integrate the groovy<br>script language (the bindings are very easy to do).&nbsp; It&#39;s the IzPack glue itself that would<br>take me the most time (as i assume would be the case with other dynamic scripting
<br>languages as well).<br><br>GroovyClassLoader classLoader = new GroovyClassLoader(this.class.getClassLoader());<br>Class scriptClass = classLoader.parseClass(new InputStream(scriptInputStream));<br>Object scriptObject =
