[rules-users] Drools Rules Mysql Configuration

[Michael Anstis]

Look at
org.drools.repository.events.StorageEventManager.registerCheckinEvent(CheckinEvent
ev).

You'll need to modify Guvnor to register your own CheckinEvent.

You can then use the following to get your DRL:-

org.drools.guvnor.server.RepositoryAssetOperations.loadAsset(AssetItem
item) to get an Asset
org.drools.guvnor.server.RepositoryAssetOperations.buildAssetSource(Asset
asset) to generate the DRL from the Asset retrieve above.
