For that I have my MemoryRepositoryService (with its binding in jbpm.user.wire.bindings.xml). I could reuse most of the commands in RepositoryService, but createDeployment has to create a new DeploymentImpl, since the one in the core depends on hibernate (LOB). And from there I have to replicate tons of classes that could have done it if it would have referenced NewDeployment instead of DeploymentImpl. usually i use protected as the default, so you could consider inheriting the existing services and just overwrite one method with your custom command. if there is a simple way on how we can make a small change to make your customizations easier, post them very concrete and we'll always consider them.
