[rules-users] Basic questions about rule deployment

Hi, I've finished my first small application using JBoss Rules. My current deployment "strategy" is that I want to have a single executable .jar file containing my application and an external (not included in the .jar) folder that contains the rules that should be used. Unfortunately, this seems to be harder, than I thought, as my application refuses to use .drl or .dsl files that are outside of the package. I'm quite sure that it's just my misunderstanding of the manual that leads to the problem, as this seems to be one of the most basic deployment approaches, as stated by the manual: " Chapter 7. Deployment and Testing 7.1. Deployment options Once you have rules integrated in your application (or ideally before) you will need to plan how to deploy rules along with your application. Typically rules are used to allow changes to application business logic without re-deploying the whole application. This means that the rules must be provided to the application as data, not as part of the application (eg embedded in the classpath). " Unfortunately I have quite some problems understanding the rest of the chapter. So I just used and modified on of the given examples. CODE/* //read in the source Reader source = new InputStreamReader(JBossRules.class.getResourceAsStream(KNOWLEDGE_FILE)); //read in the DSL Reader dsl = new InputStreamReader(JBossRules.class.getResourceAsStream(DOMAINSPECIFICLANGUAGE_FILE)); //Use package builder to build up a rule package. //An alternative lower level class called "DrlParser" can also be used... PackageBuilder builder = new PackageBuilder(); //Use the following instead of above if you are using a DSL: builder.addPackageFromDrl(source, dsl); */CODE If I use KNOWLEDGE_FILE = "/Rules_withDsl.drl"; DOMAINSPECIFICLANGUAGE_FILE = "/Rules_withDsl.dsl"; it all works wonderfully... but then the rules are within my .jar :-( So I tried to change this into a folder outside the package: KNOWLEDGE_FILE = "C:/test/Rules_withDsl.drl"; DOMAINSPECIFICLANGUAGE_FILE = "C:/test/Rules_withDsl.dsl"; Now, it doesn't work any more, because the "getResourceAsStream" returns null pointers... Any idea? Thanks -- View this message in context: http://www.nabble.com/Basic-questions-about-rule-deployment-tf4601653.htm... Sent from the drools - user mailing list archive at Nabble.com.
