Tiles documentation

[Ray Clough]

It seems to me that the config info at 
http://tiles.apache.org/tutorial/configuration.html is incomplete and in 
error.  1)  There is no filter-mapping or servlet-mapping specified.  2) 
the tiles definition files are specified both for the servlet and the 
filter.  There is no statement about using one or the other.  The only 
other instruction is the alternative of using a context parameter.

How is the mapping to be specified.  My guess is that if the filter and 
servlet are mapped to "*.tiles", for example, all forwards to 
"xxx.tiles" will be rendered by Tiles.  Is that correct?  Do both the 
filter and servlet need to be mapped.  If either is not mapped, is it 
actually used?  Must they be mapped to the same value?

Thanks,
