Sub-apps using Tiles/SecureRequestProcessor

[Greg Hess <gh...@wrappedapps.com>]

Hi All,

I am currently preparing to migrate one of my Struts apps to separate
modules as it is currently developed in modules and I would love to simplify
the integration of the modules.

My application consists of two modules. The main application module is using
the SecureRequestProcessor plug-in to handle http/https switching and the
Struts template tags for view layout. The second module is the
administrative module and it has recently incorporated the use of Tiles.

As far as I can see from the archives the Tiles distribution from jakarta is
compatible with sub-apps. I am wondering if all the sub-apps must use Tiles
and if the SecureRequestProcessor supports sub-apps as I have experienced
some errors with some quick tests with the SecureRequestProcessor as a
sub-app? The following error occurred with the SecureRequestProcessor being
used as a plug in in the sub-app and parent app.

500 Servlet Exception

When I removed SecureRequestProcessor plugin from the sub-app all worked
fine except for my http/https switching. I am looking for a some wisdom that
might help me in this module integration.

Many Thanks,

Greg

  Hi,

  Tiles doesn't require that all your subapps use them. But, you need to 
use the TilesRequestProcessor, or a subclass of it, for each subapps 
using tiles. The
TilesRequestProcessor is set by the tiles plug-in. So, if you want to 
use tiles and SecureRequestProcessor in the same subapps, you need to 
provide a compatible RequestProcessor. I don't know if 
SecureRequestProcessor is compatible with subapps.
  Let us know if you success or not in your approach. This can help 
other users !
