Why does Tiles 3 require so many dependencies?

[Andrey Botalov <bo...@gmail.com>]

I write a very simple Tiles app that doesn't use any features besides 
those in http://tiles.apache.org/framework/tutorial/basic/index.html. 
You can see stuff relevant to Tiles at https://gist.github.com/3324728

When I try to run it, I become overloaded with NoClassDefFoundErrors. 
Many of those are in \lib\optional folder of tiles-3.0.1-bin.zip so I 
don't think that I need them (e.g. spring-core, spring-web, ognl,mvel). 
Do I need them in my simple Struts app?

For the purpose of the tutorial, we use CompleteAutoloadTilesListener, 
which loads all the possible features and therefore requires many 
dependencies. Once you get familiar with those features, you can choose 
the ones you need and you can build your own configuration. See the 
configuration reference here: 
http://tiles.apache.org/framework/config-reference.html.

For a minimal set of features, you can replace 
CompleteAutoloadTilesListener with SimpleTilesListener. See the 
difference here: 
http://tiles.apache.org/framework/config-reference.html#Simple_configuration. 
For many real world applications though, the minimal set may not be 
enough (I myself can seldom do without an expression language and 
multiple tiles.xml files).

Hope this helps,
Nick
