> Several cocoon users have reported a caching problem when
> using cocoon: pseudo protocol with ServerPagesGenerator. Here's an example
> pipeline:
> <map:pipeline type="noncaching">
>   <map:match pattern="foo">
>     <map:generate type="serverpages" src="cocoon:/bar"/>
>     <map:serialize type="html"/>
>   </map:match>
>   <map:match pattern="bar">
>     <map:generate src="foobar.xml"/>
>     <map:transform src="XSLwithXSP.xsl"/>
>     <map:serialize type="xml"/>
>   </map:match>
> </map:pipeline>
> The XSL page (XSLwithXSP.xsl) is used to extend the original XML page 
> (foobar.xml) with XSP instructions (ESQL etc.), and the result is fed to the 
> ServerPagesGenerator (resource "foo") using "cocoon:" pseudo protocol.
> Calling "bar" results to an updated page. No problem here. But calling "foo" 
> always results to a cached page. So it seems that the Java code generated by 
> the ServerPagesGenerator is not updated! The only thing that seems to help is
> to remove the work-dir and restart Tomcat. Doing this after every change
> is very frustrating and slow. Here's some experiments on the subject:
> http://www.mail-archive.com/cocoon-users@xml.apache.org/msg19064.html
> If any of you developers can find and fix the problem, please do. I consider 
> this as a major blocker in the framework. This is because pipelines like the 
> example above can be used to create very flexible and general web applications. 
> (For example, a complete database management system with one descriptor file).
> Thanks A LOT in advance,
> Tuomo
