Hi all,

I'm trying to use the cinclude transformer on a document that has =
cinclude references to quite a few large files.=20
The result of this transformation doesn't need to be the most =
up-to-date, so I'd like to use cached cinclude (cinclude:cached-include) =
which would expire once a hour.

I'm following documentation for cinclude here: =
http://cocoon.apache.org/2.0/userdocs/transformers/cinclude-transformer.h=
tml

Here are my relevant configs.

sitemap.xmap:

	<map:match pattern=3D"rssmain_test">
		<map:generate src=3D"docs/custom/cinclude_test_src.xml"/>
		<map:transform type=3D"cinclude">
			<map:parameter name=3D"expires" value=3D"3600" />
		</map:transform>
	<map:serialize type=3D"xml" />
	</map:match>

cinclude_test_src.xml:

	<sites xmlns:cinclude=3D"http://apache.org/cocoon/include/1.0">
	  <cinclude:cached-include src=3D"docs/custom/site1.xml" />
	  <cinclude:cached-include src=3D"docs/custom/site2.xml" />
	  <cinclude:cached-include src=3D"docs/custom/site3.xml" />
	  <cinclude:cached-include src=3D"docs/custom/site4.xml" />
	  <cinclude:cached-include src=3D"docs/custom/site5.xml" />
	  <cinclude:cached-include src=3D"docs/custom/site6.xml" />
	</sites>

According to the cinclude documentation, I also need to add the =
following component to cocoon.xconf, which I've done:

	 <component =
class=3D"org.apache.cocoon.transformation.helpers.DefaultIncludeCacheMana=
ger"
	            =
role=3D"org.apache.cocoon.transformation.helpers.IncludeCacheManager">
	 </component>

Having done that, cocoon started generating internal errors, and this =
what I've found in the core.log:

java.lang.ClassNotFoundException: =
org.apache.cocoon.transformation.helpers.DefaultIncludeCacheManager
...
<stack trace here />
...

I didn't find =
org.apache.cocoon.transformation.helpers.DefaultIncludeCacheManager nor =
org.apache.cocoon.transformation.helpers.IncludeCacheManager in cocoon =
2.03, and that's the version we're using. However, they are present in =
the last milestone of 2.1.
Does it mean that the documentation is 2.1 specific?
Is there a way to use cached cincludes in 2.0.3?

I built the last 2.1 milestone and tried to use =
DefaultIncludeCacheManager, IncludeCacheManager and other related =
classes in 2.0.3 (by dropping them in WEB-INF/classes/...), but there =
appears to be a lot of other dependencies.

Upgrading to 2.1.0 is not an option at the moment, so I would appreciate =
any suggestions on getting cached cincludes to work with 2.0.3.

Thanks,
- Ed Y.
