[jbpm-dev] [JBPM 5.x] service task repository

Tue Mar 13 18:56:39 EDT 2012

Well, there is guvnor-repository that provides low level operations to (in
theory) a Guvnor repository. However all our classes, integrity logic and
means to expose it as an external service (ie REST, WebDav) are AFAIK in
guvnor-webapp-core which you can't deploy outside of a container.... but
this, in theory, could be split into different modules to provide better
access. I am sure you appreciate exposing REST needs a container however
WebDav might not. IDK.
