[rules-users] Does guvnor 5.1 uses hibernate ?

[Geoffrey De Smet]

Guvnor doesn't uses a CMS, not a relational database.
Currently guvnor 5.1 supports jackrabbit as CMS, but 5.2 will also 
support modeshape.

The hibernate jar probably comes from drools-compiler which supports 
HQL's in rules, and therefor might need to be marked optional so it's 
not included in guvnor if not needed.
However, since we might want to support HQL editing in guvnor too (maybe 
there's already an experiment), we 'll have to check more carefully if 
we want to exclude hibernate or not.
In any case, since it's just for the HQL editing AFAIK, you can probably 
safely remove it for any other scenario.
