intermittent exception in TilesRequestProcessor

[Harish Kumar <ha...@gmail.com>]

Hi,
I'm getting the below exception, but only after hot-deploying a class file
-- for example, an ActionForm-derived class. I believe the error occurs only
on pages that use the particular deployed class.
I just added the Tiles plug-in and configured the TilesRequestProcessor.
I do have a tiles-def.xml which is not being used yet except for a very
simple test page. But no one is currently working with the test page; no
other pages use any Tiles features at all. The exception seems to occur on
any page I'm running WebLogic 8.x and suspect the problem is
server-specific.

Thanks.
Harish
