An Eclipse plugin is needed that can act as the Derby System Home, enabling other plugins to use derby databases for meta-data
------------------------------------------------------------------------------------------------------------------------------

         Key: DERBY-897
         URL: http://issues.apache.org/jira/browse/DERBY-897
     Project: Derby
        Type: New Feature
  Components: Eclipse Plug-in  
    Reporter: Thomas Hallgren


Some Eclipse-plugins make use of rather complex meta-data and it would be very beneficial to use use Derby databases as storage mechanism, especially when transaction stability etc. is of great importance.

If a plugin wants to use a Derby database, it needs to somehow define the System property 'derby.system.home'. This is problematic since Eclipse plugins, created by different entities in different parts of the world, must be able to coexist. It is therfore important to publish a 'canonical' way of sharing a Derby System. A collision between different ways of doing this is bound to happen sooner or later otherwise.

I propose a new Derby plugin that would expose the derby packages (short of the internal ones) so that other plugins may express a normal plugin dependency to it. This plugin will also define the 'derby.system.home' to appoint its own 'state location'. The current derby nature would not be used since it seems targeted at application development rather than having several plugins sharing the same Derby system.
