How do I control the order in which deployers that both rely on ServiceMetaData components to have these services started in the correct order? Its the old issue of lacking explicit service dependencies, having a coarse module based ordering mechanism. Currently the war deployer is a AbstractSimpleRealDeployer with the same relative order as the RARDeployer. A war with a nested rar has no guarentee of correct startup of the rar without an explicit dependency on its service. Maybe it will be irrelevant in the end as interaction with the rar services will be through injection and the required dependencies will show up, and this will be a non-issue.
