Micheal is right in that using RMI more tightly couples you to the
underlying asset object model, but it also gives you a lot of flexibility.
For instance, every time our object model changes, as part of the build
process, the package is created/updated to include the updated JARS, updated
header section, and updated code for the enumerations. It will then validate
the package, build it, and create a new snapshot with the version of the
model.
To Micheal's point, I had to update my code to handle the change in the way
header is stored in BRMS vs. Guvnor. In BRMS it was a property on the
PackageItem, but now it is an AssetItem in the package.
Here is a sample of connecting to the JCR, then using said session with the
Drools API
// THIS first part is JackRabbit's RMI code
ClientRepositoryFactory factory = new ClientRepositoryFactory();
Repository repository = factory.getRepository(rmiURL);
Session session = repository.login(new SimpleCredentials(username,
password.toCharArray()));
// THIS IS DROOLS API
RulesRepository rulesRepository = new RulesRepository(session);
With the rulesRepository, you can than get packages out
PackageIterator iterator = rulesRepository.listPackages();
Create a new package
rulesPackage = rulesRepository.createPackage(packageName, packageName);
and so on...

Hi Dave,
Is it possible to share the code snippet with us. I don't have any
experience of Jackrabbit and RMI. Any concrete example will be helpful.
Cheers
