Hi Neil,
The approach I use is to implement
org.apache.tiles.definition.DefinitionsFactory and instruct Tiles to use
your DefinitionsFactory
web.xml:
<context-param>
<param-name>org.apache.tiles.definition.DefinitionsFactory</param-name>
<param-value>myDefinitionsFactoryImpl</param-value>
</context-param>
The custom DefinitionsFactory implementation receives requests for a
tile by name and can load an alternative tile or reads from an
alternative set of tiles definitions whenever you wish.
I use it to load tiles-<theme>.xml files. If a theme is enabled, it
returns the themed tiles if found, otherwise it delegates to the default
UrlDefinitionsFactory. You could do the same thing using the hostname.
Incidentally, Sitemesh's DecoratorMapper's provide equivalent
functionality (http://www.opensymphony.com/sitemesh/dm.html). If you're
just changing page decoration it may be less effort to use.
Hope that helps,
Jeromy Evans

Great! I will use tiles.
I am confused about know to know which set of tiles
to load. The sites will have different domain names.
Can I tell tiles to use a set based on that?
Thanks,
Neil

Then I would suggest Tiles. This would be as easy as getting
wet in a pond.

The functionality will be exactly the same for

How do I tell struts to load a given set of
tiles based on the domain name?
Thanks,

Hi Neil,
When you say Look and Feel are you referring to just the
visual aspects of
the site or are you referring to a marked difference in front-end
functionality?
If you are not providing differing functionality or the
functionality being
provided is mostly similar to the current site, your best
approach will be
to use CSS to make one site look and feel different than the
other site.
Additionally, if your current site is not already using
Tiles, you should
consider refactoring to add this flexibility. With a Tiles
and CSS-based
approach you can completely re-use your current middle and
back-end tiers
with little or no modification.
You do not need a whole new set of JSPs, simply a flexible
view structure
and a well-defined view decoration strategy (Tiles and/or CSS
to modify
structure and CSS to modify the presentation).
Lastly, if you are relying on certain behaviors (Javascript),
these should
be designed such that they are generic. As such they may be
applied to one
or more of your sites independent of the structure and
presentation of a
given site.
The only reason you would need an entirely different set of
JSPs would be if
they were providing a completely different application of the
underlying
information (back-end). As there should be no business or
control logic in
your JSPs, I still would think about the above approach
before taking such
drastic measures as re-creating everything.
HTH,
-Rod

Subject: [S2] Best approach to separate look & feel with same
backend code
Hello:
I am trying to figure out the best way to do this:
I have two domains.
I am going to develop two different web sites
which will use the same backend database and have
the same functionality, just a different look and
feel.
Should I:
1. Create two separate webapps? That seems poor
since there will be a lot of duplicated code.
2. Create one webapp and pass around a site identifier?
Then, I can load the correct set of JSPs based
on the identifier?
Any suggestions for the best way to do this?
Thanks,
Neil
