Following what Grzegorz mentioned earlier, I would say, that transaction definitions within
domain-app-ctx are global for all blocks as long as one put a dependency to the domain.jar
within the blocks pom.xml. Then it is just up to the blocks using domain.jar to include 'your'
statement to META-INF/cocoon/spring/appCtx.xml to tell that there is another appCtx in the
classpath. Actually there is only one global webAppCtx, including all sub-contexts and there
should be no problem with transactions. Or do I miss something? I am not sure in wich cases
there should be other transaction-rules within some blocks, because I only want to use transactional
behaviour out of my domainmodel and never want to let cocoon do any DB-stuff itself.
