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...
