Re: [rules-users] Fact Names in a Model
Even if you get the packages using REST API, you still need to add them to
a kbuilder (you don't need to have multiple kbuilders. 1 kbuilder can
contain multiple packages).
What you can do if you don't want to manually add all the packages to a
kbuilder is to create a change-set, which is basically an xml pointing to
all the resources you want to add. Then, you add the change-set to the
kbuilder with ResourceType.CHANGE_SET. For more information about
change-sets, please refer to the documentation.

Re: [rules-users] Fact Names in a Model
Hi Esteban,
*Listing Packages*
KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase();
kbase.addKnowledgePackages(kbuilder1.getKnowledgePackages());
kbase.addKnowledgePackages(kbuilder2.getKnowledgePackages());
int flag=1;
for(KnowledgePackage kp :kbase.getKnowledgePackages())
{
System.out.println("Package Names are"+kp.getName());
}
The code which i had written here can possible to retrieves the
list of packages.Here,I added snapshots to kbuilder1,kbuilder2 and through
kbase iam retrieving the packages list.Is it is possible to retrieve list of
packages without adding package snapshots to kbuilder.???It means i think
through repository.xml...How can i achieve that???
Even i referred REST API but unable to retrieve XML nodes from it

Re: [rules-users] Fact Names in a Model
Well, there might be a way to do what you want, but you will need to go to
the dark side of drools :) (basically means magical castings)
A KnowwledgeBase contains one or more packages, and inside the packages is
where the Declared Types live.
So, using this code (I didn't test it but it should work), you can access
all your declared types of all the packages in a knowledge base:
Set declaredFactTypes = new HashSet();
Collection knowledgePackages =
kbase.getKnowledgePackages();
for (KnowledgePackage knowledgePackage : knowledgePackages) {
//the key of this map is the simple name of the declared type
and not the fqn
Map typeDeclarations =
((KnowledgePackageImp)knowledgePackage).pkg.getTypeDeclarations();
//collect all the keys in the set
for (String type : typeDeclarations.keySet()) {
//store the fqn of the declared types to avoid name
collision
declaredFactTypes.add(knowledgePackage.getName()+"."+type);
}
}

Re: [rules-users] Fact Names in a Model
This should contain all the code you need. Some of this is NOT from
the "stable API" although it retrieves only information that's bound
to be stable. (Another thing I keep harping about, from time to time.)
Below is a class that does some cross referencing as any serius SW
develoment would need for documentation of its DRL code, and it irks
me considerably that you have to use the "instable API" for simple
things like that.
It's working with 5.2.0, so it should do so with 5.3/4.0, but -
remember, "not stable" -- you never know. It has not been tested
extensively, e.g., for nested combinations of various flavours of
"from". It does not handle "eval" expressions and whatever goes on in
constraint expressions.
Invoke it, e.g., like this:
RulesByClasses rbc = new RulesByClasses();
rbc.print( kBase );

Re: [rules-users] Fact Names in a Model
Thank you Esteban,
I referred API,I'm able to retrieve rule-names present in a package.But
could not able to retrieve Declarative Model names,and Facts present in that
declarative Model in that package.Here,is my code to retrieve rule names in
a package.
//.Added Kbuilder to
Collection kpackages = kbuilder2.getKnowledgePackages();
for(KnowledgePackage kpackage : kpackages) {
System.out.println(kpackage.getClass().getDeclaredClasses().toString());
for(org.drools.definition.rule.Rule rule :
kpackage.getRules()) {
System.out.println(rule.getName());
}
}
Can I enhance this code to get Model names and Fact names(which are present
in that model).
Please help me..I'm struggling in this since last week
