Re: cached cinclude doesn't work on 2.0?

[Joerg Heinicke]

Instead of Cocoon 2.1 from CVS you can use Cocoon 2.0.5 from CVS 
(hopefully released at the beginning of July). It has at least the 
caching implemented in the CincludeTransformer, but I don't know 
anything about the DefaultIncludeCacheManager.

Hi all,

I'm trying to use the cinclude transformer on a document that has cinclude references to quite a few large files. 
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.html

Here are my relevant configs.

sitemap.xmap:

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

        <sites xmlns:cinclude="http://apache.org/cocoon/include/1.0";>
          <cinclude:cached-include src="docs/custom/site1.xml" />
          <cinclude:cached-include src="docs/custom/site2.xml" />
          <cinclude:cached-include src="docs/custom/site3.xml" />
          <cinclude:cached-include src="docs/custom/site4.xml" />
          <cinclude:cached-include src="docs/custom/site5.xml" />
          <cinclude:cached-include src="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="org.apache.cocoon.transformation.helpers.DefaultIncludeCacheManager"
                    
role="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,
