Hi,
COCOON3-105 changed the way how blocks are deployed in a Cocoon webapp: 
this affects only C3 SNAPSHOTS of course, and even in this case you can 
restore the old (i.e. 2.2) way of connecting blocks.

I've prepared a simple C3 project at [1] that shows how to deal with 
this: the README there should be enough to get it working and a quick 
look at sources can help in understanding what has changed "under the hood".

More specifically, as you can see from [2], the block mysite2 can refer 
to block mysite1's resources as

<map:read 
src="jar:classpath:lib/mysite-${project.version}.jar!/COB-INF/{map:1}.xsl"/>

where ${project.version} is changed by Maven at build time into the 
version declared in pom.xml.


We need of course to provide a proper documentation for how to get 
started with C3: I've opened COCOON3-119 for this.
Hope this helps, in the meanwhile.

Regards.
