Guvnor repository backward compatible?
by Sean Su
While evaluating and building rules in using Guvnor 5.5, we have noticed
that there will be some major changes in 6.0. We have some concerns that
the repository (rules) built using 5.5 may not be accessible by Gunvor 6.0.
Does anyone know anything about this? Do we have document about 6.0? It
seems the document in the 6.0 beta download has the old content.
Also what is the estimated release date for 6.0?
Thanks

Guvnor 5.3 on WebSphere 8.5: detailed question
by drdaveg
I've been trying to run Guvnor on WebSphere at an IBM shop. I'm using Guvnor
5.3GA for help under our support contract with RedHat. In previous posts,
people have recommended to get Guvnor to work, nearly unmodified, under
WebSphere by disabling servlets, getting particular versions of the software
to run on specific versions of WebSphere by coincidence, etc. These
approaches have not gotten very much Guvnor functionality running so I am
trying:
1. To remove the Seam-specific calls from Guvnor and
2. Inject objects using appropriate WebSphere-based libraries.
In doing (1) I've removed the Seam-specific annotations but don't see any
references to "remote.js" in the source code. Am I missing references that
are there by searching incorrectly, am not including the correct files - or
are these automatically generated by the GWT-based dynamic code generation?
Also, any thoughts on improving my approach would be welcome!

Spam
by rjr201
Sorry to keep going on about this.. I realise that the nabble interface is
only a mirror of the mailing list, but currently it's completely swamped by
spam. I'm sure a lot of people using drools for the first time come to this
forum for help/guidance, and it's not very inspiring when there is roughly 1
real post to every 8 spam posts.
I'm guessing it's not an easy task just to filter it out, but is there a way
that I can manually delete it? I check this forums most mornings, and it
would take me very little time to remove it..
