The init() method signature for the PlugIn interface was changed from:

  init(ActionServlet, ApplicationConfig)
to
  init(ActionServlet, ModuleConfig)

in Nov 2002 in between the Strust 1.1 beta 2 and Strust 1.1 beta 3 versions.

Also the stuff in initApplicationPlugIns() method in ActionServlet was
factored out into the initModulePlugIns() between Beta 2 and 3 but it looks
from the stack trace its using the old version.

I think its picking up a struts jar which is pre Struts 1.1 Beta 3 - but
your app was developed with the  Struts 1.1 release version. If thats true
he's either deployed the wrong struts.jar or has an old version hanging
around.
