Do you know of a good resource to working with blocks? I've found a couple
tutorials but they seem very basic and I'm still having trouble understanding
how the application I've got is organized. Could you help me how to modify the
block to do what you described?
In looking at the one of the block.xml that I've got, I see something like this:
<container name="c">
<services>
<service type="a.b.c.Service">
<source>service</source>
</service>
</services>
<component name="service" class="a.b.c.ServiceImpl" activa
tion="lazy"/>
<component name="c2" class="a.b.c.c2Impl" activa
tion="lazy"/>
...
</container>
I turns out that the only component that I need to modify is "c2", not the one
that is named in the service definition. Will what you describe still work even
if the component is not directly the service?
Also, the application I've got seems to have a number of block.xml files but
none of them seem to be in the main directory? How do I figgure out how they
are tied together and which is the "main" one?
Thank you for your help.

Yes, but one of two things is required;
Either you have to modify the caller to lookup both services (of the same
type, but with different keys and manual assembly of which implementation is
looked up with which key), OR
assemble the application so that the 'original caller' looks up your 'new
extension' and that the 'new extension' looks up the 'original service impl',
and calls it for each call made by the 'original caller'.
The second choice, should give you zero changes to the original Java source
code, and only need to work on the blocks.
