Re: [rules-users] No accumulator function found for identifier
There was an error in the IDE where different configuration files were not correctly loaded from the user classpath when creating a PackageBuilder. I have fixed this in trunk (JIRA JBRULES-1614). For now, I suggest you use the workaround as suggested by by Steve (thx Steve !). Putting the configuration file in your home dir should work.

Re: [rules-users] MissingPackageName Exception | Eclipse | brl to drl
Hi, as mentioned in the docs, you could use an ant task. So if you look at the sources drools-ant/src/main/java/org/drools/contrib/DroolsCompilerAntTask.java you will notice, that it adds the package file explicitly. In your case, try this: String rulePackageContent = FileUtils.readFileToString(rule.package); String brl = FileUtils.readFileToString(file); String outputDRL = rulePackageContent + write.marshal(read.unmarshal(brl)); HTH, Jarek - Original Message - Hi, We created a brl rule using guided editor in Eclipse 3.3 On trying to create a rule package we are getting a 'MissingPackageName' exception. As like a brl rule created in BRMS, on eclipse, the DRL source of the created brl shows only the rule body `with the exception of the package statement and imports. Our understanding is that packagebuilder in drools-compiler should pick the package name and the imports defined in the rules.package text file. Things work fine for business rules created in guided editor in BRMS. Are we missing something obvious here? or there isn't a way to compile and test the brl files created in Eclipse. Any inputs are highly appreciated. Thanks. Code snippet fyi File file = new File(test_brl); BRXMLPersistence read = (BRXMLPersistence) BRXMLPersistence.getInstance(); BRDRLPersistence write = (BRDRLPersistence)BRDRLPersistence.getInstance(); String brl = FileUtils.readFileToString(file); String outputDRL = write.marshal(read.unmarshal(brl)); System.out.println(outputDRl+outputDRL); //Output DRL here doesn't show the import statements and package name PackageBuilder builder = new PackageBuilder(); builder.addPackageFromDrl(new StringReader(outputDRL )); //Missing package name for rule package exception occurs here Package pkg = builder.getPackage(); RuleBase ruleBase = RuleBaseFactory.newRuleBase(); ruleBase.addPackage( pkg ); WorkingMemory workingMemory = ruleBase.newStatefulSession(); workingMemory.insert(obj); workingMemory.fireAllRules(); ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
Re: [rules-users] question on JSR94 compliant jars
Drools is embeddable in any java application, if you add the proper dependencies. The dependencies vary according to what features your application uses.

[rules-users] https package url
Hi all, I use the Business Rules Server to deploy rules packages and I use the URL feature to consume them. It works fine but I am concern about security in rules requests. I've seen in the documentation that we can use SSL for BRMS login security but what about url requests to rules packages ??

Re: [rules-users] Re: Ruleflow-group attribute causing rule to not fire
Thanks Kris, On 5/21/08, Kris Verlaenen [EMAIL PROTECTED] wrote: This is expected behaviour, let me try to explain. By adding the ruleflow-group attribute to your rules, you are stating that these rule should not be executed as normal, but that the order in which these rules should be executed is specified by a ruleflow. Activations will be created for rules that are part of a ruleflow-group, but they will only be executed if the ruleflow-group is activated. To make sure that rules with a ruleflow-group are executed, you must: 1. Create a ruleflow that specifies when the rules should be activated (using ruleset nodes) AND 2. Start the ruleflow whenever appropriate. My guess is that you are not starting the ruleflow, so the corresponding ruleflow-groups are never activated. You can either start a ruleflow manually in your code (workingMemory.startProcess(id_of_your_ruleflow), for example right before calling workingMemory.fireAllRules()), or using a rule (probably with a high salience) with as consequence drools.getWorkingMemory().startProcess(id_of_your_ruleflow). It is also normal that all other rules that are not tagged with a ruleflow-group attribute just execute as before, even in the presence of ruleflows, both can be used side by side.

I am currently evaluating Drools 4.0.7 for use in our new project. Basically I have been writing a bunch of individual rules and things have been fine, the rules that I expected to fire were fired, etc, etc. I then proceeded to investigate rule flows. I started innocently enough i.e. adding the ruleflow-group attribute to some of my rules. I also defined a ruleflow mapping (.rfm). I then reran my unit-tests (WITHOUT reading the rules in as rule flows) and some of my rules were no longer firing!!. I added an Agenda Listener to my code and 1. without the ruleflow-group attribute, activations were created, and fired. 2. with the ruleflow-group attribute, activations were created but not fired. Using the debugger yielded the same logical outcomes i.e. without the ruleflow-group attribute, my breakpoints were hit, but with the attribute specified, none of my breakpoints were hit. My question is: Is this behavior expected? And why? Especially since some other rules (with the attribute specified) continued to work. I've read the documentations as much as possible, but I am really new to this field so I might not even know what questions to ask either. Any help would be greatly appreciated.

RE: [rules-users] DSL expanders for overriding rules question
I've done as suggested and created the feature request as JBRULES-1615.

In fact, the expander declaration is only used by the eclipse plug-in. If you need to use more than one expander per rule file, you will have to use the API directly. This is probably something to improve in the future. May I ask you please to open a feature request? Kris, can you confirm that this is the case?

I posted a similar question several days ago but didn't get any replies. Have you deployed BRMS behind SSL? I haven't so far, so can't say if the RulesAgent can use https URLs. Also, have you been able to enable security? Which app server are you using? If security is enabled and BRMS login is password protected, how would the RulesAgent be able to consume packages from the URLs without using a username/password?
