[rules-users] Rules compilation error with OSGi integration (6.1.0.Beta3)
Hello. We have a very simple rules file that works as expected when running as a JUnit test in Eclipse with Maven dependencies, but fails when it is executing in ServiceMix with OSGi integration. The code is just like : raw MapString, Object dialog = new LinkedHashMap(); KieSession kieSession = kieContainer.newKieSession(MyKSession); kieSession.setGlobal(dialog, dialog); kieSession.insert(problem); kieSession.fireAllRules(); kieSession.dispose(); The rules file : And the kmodule.xml : The compilation error is about Java 7 syntax elements (as generics or thousand separators in number literals for example), and seems to indicate that in this case the compiler is not the same, and it expects another Java syntax. No error is reported when the KieContainer is created from the KModule.xml, but the following error occurs when using it for KSession creation. This occurs both with the prepackaged feature (http://repo1.maven.org/maven2/org/drools/drools-karaf-features/6.1.0.Beta3/drools-karaf-features-6.1.0.Beta3-features.xml), or with an adapted one. For example, the Maven dependancies classpath in eclipse mentions newer versions of the Eclipse's ECJ. But changing the version of bundles has no effect... What is missing in the feature to activate the correct rules compiler ? Thanks for your help ?

I use the term folder as we don't support same package (which would imply if the same package existed in different JARs we'd include all DSL files - we do not). The expander keyword is, AFAIK, deprecated. DSL/DSLR expansion depends upon the files being in the same folder. @Mario, @Mark, @Edson.

Do I have to load each DSL files programmatically or is there a way to load it automatically by the kmodule.xml (and if it is the case, how can we handle the parsing order of these files ?) ? - An underlying question is is this a good practice to divide DSL files ? I would like to translate all my rules in french and to put the generic translations in a unique DSL file to reuse it in all of my different DSLR files. - I noted that we can use more than one DSL file for one DSLR file (it works at the runtime) but when it is the case the DRL viewer of the DSL rule editor does not work and I don't have autocompletion. I tried to put several expander instructions but it fails. Is there a way to make it work ?

[rules-users] newbie question about KnowledgeBuilder
Hi, I'm inheriting Drools 6.0 application where all rules are in one huge drl file. Would behavior be different if I broke rules into multiple files and loaded with multiple calls to KnowledgeBuilder.add()? Also, KnowledgeBuilder is being created with each session: KnowledgeBuilder.newKnowledgeBuilder() and then knowledgeBuilder.add(). Since rules don't change, any reason why can't create KnowledgeBuilder at startup and share it? Is it thread safe and can it be re-used?

Re: [rules-users] Drools and GPU
I agree with Wolfgang... My first version of the rules regarding expiration of events in a length sliding windows took 120s in my benchmark. After thinking a little bit, the second version took 2s. Changed dramatically the behavior of the application, now can process several thousands of events in no time! If I were you, my first try was to optimize the rules, doing some benchmark/profiling, to know where the bottleneck is.
