Hello All,
I am investigating Drools Guvnor for its rule authoring capabilities.
*The site says the Gunor License is ASL but it packages hibernate jars.
Hibernate license is LGPL.*
I removed the hibernate jars from Guvnor & still it is able to perform db
operations.
Note: Guvnor is using Oracle database as a repository (not using the default
file system repo). Repository file attached.
*Question:
1. Does Guvnor uses hibernate jars? If yes then in what scenarios. (I am
able to do create rules in repo (database) without hibernate jars)
2. Is hibernate a leftover from old versions of drools ? Why is it packaged
with drools 5.1 guvnor release ?*
*Tasks performed to proove that Guvnor does not have any dependency on
hibernate.*
1. Stopped the JBOSS server
2. Removed hibernate jars from guvnor lib folder.
3. Started Guvnor
3. Created rules in guvnor. I verified that the new rules were getting
stored in the database.
Hence no dependency of guvnor on Hibernate.
