I'm trying to implement a reusable lifecycle extension block that I can include in other services. So far I have the lifecycle block built
Mentally I see the extension block living in a container and blocks that use it living in subcontainers:
+-----------------+
| Lifecycle block |
+-----------------+
|
+---------------+---------------+
| | |
+---------+ +---------+ +---------+
| svc A | | svc B | | svc C |
+---------+ +---------+ +---------+Based on the documentation for block.xml's include I think that the closest I can get would be a wrapper container that includes all blocks:
+------------------------------------------------------------+ | +---------+ +---------+ +---------+ +-----------------+ | | | svc A | | svc B | | svc C | | Lifecycle block | | | +---------+ +---------+ +---------+ +-----------------+ | +------------------------------------------------------------+
Right now I'm trying to test the lifecycle extension by including the block and running against a separate test block's compiled classes. (no jar, but meta info is built.
+------------------------------+ | +-----------------+ | | (svc A) | Lifecycle block | | | +-----------------+ | +------------------------------+
I'm under the impression that this should work, but I can't get the test block (svc A) to recognize the service id of the lifecycle block. This is the output of running:
