Think of the Global Area as a place where assets can be stored to share across packages. When you build a package assets linked from the Global Area will be included. This package is the KnowledgeBase, the runtime, with which rules will lead to activations. It is impossible to upload FACTS to Guvnor, only their definitions i.e. the model.

Historically, knowledge bases (e.g. think of basic prolog or ontologies) are more "static" and contain both facts and rules. Maybe it would be more appropriate to think of those facts as "initial" rather than "global". In fact, you can write a rule : rule "Init" when then insert( new X(..) ); insert( new Y(..) ); end I think it could be desirable to support a more compact syntax, e.g. declare fact X( val1, val2, ... ) or maybe, more mvel-like: declare fact X().{ field=val, ... } As always, open to discussion on feature requests :) Davide -- View this message in context: http://drools.46999.n3.nabble.com/Guvnor-Help-tp4018290p4018303.html Sent from the Drools: User forum mailing list archive at Nabble.com.

The Global Area is a container for assets you might like to share across different packages. For example, you might have a POJO Model that you want to use in two different packages. Assets in the Global Area are *not* in packages unless you import them into the package. Rules are assets so the same principle applies: if you have a rule you want to share in multiple packages, define it in the the Global Area and then import it into the packages in which it is needed.

Hi, You're basically right, but your terminology confused. Firstly, I'd be surprised if the package in Guvnor would compile without importing the POJO Model from the Global Area into package XYZ. When attempting to compile package XYZ with rule "age and status" the Classes used therein will not be found and hence compilation fail. Secondly, the "Model" (whether POJO, as you are doing, or otherwise) contains Classes. Not Objects. Nothing will fire even if everything else is correct. If you have not already done so, and I am beginning to feel you have not, please read the Drools Expert user-guide. This explains how the Rule Engine functions. Thirdly, an example of where you might want to share a single POJO Model between packages could be:- Mortgage Model containing Classes for: Applicant, Property, MortgageOffer Packages: org.yourco.mortgages.england.south, org.yourco.mortgages.england.north, org.yourco.mortgages.england.west, org.yourco.mortgages.england.east With kind regards, Mike On 28 June 2012 09:49, abhinay_agarwal <abhinay_agarwal(a)infosys.com&gt; wrote:

hey mike, To /use a POJO model in a specific package after importing /it from Global, /we need to create a Global variable inside the EDIT -> Configuration part of the package/... Only after this is done can i make rules inside the package using the imported model.. But, in drools-expert doc its said that "/It is strongly discouraged to set or change a global value from inside your rules/"..and..."/Globals are not designed to share data between rules and they should never be used for that purpose/" but again you told me that "/*Rules are assets so the same principle applies: if you have a rule you want to share in multiple packages, define it in the the Global Area and then import it into the packages in which it is needed*/" M a bit confused..can yu please explain !! -- View this message in context: http://drools.46999.n3.nabble.com/Guvnor-Help-tp4018290p4018429.html Sent from the Drools: User forum mailing list archive at Nabble.com.

hey mike, from uploading facts i meant uploading the jars with classes.. when you say that "Think of the Global Area as a place where assets can be stored to share across packages"..does it mean that if i make a rule in GLOBAL AREA..will that rule be taken into consideration for all the other packages ??? -- View this message in context: http://drools.46999.n3.nabble.com/Guvnor-Help-tp4018290p4018305.html Sent from the Drools: User forum mailing list archive at Nabble.com.
