The 2 problems I'm currently facing are: 1.- There is no droolsjbpm-integration 5.6.x branch in github. 2.- I'm using jbpm 5.4.1-SNAPSHOT but this version still depends on drools 5.5.1-SNPASHOT. I think a new jbpm 5.5.x branch is needed.

If so, Is it possible using Drools? Can we provide the where conditions dynamically through Drools.i.e, the flow should be from Drools to DAO layer? Is it possible to drive the flow from Drools to Hibernate providing the where conditions dynamically. I came to know that hibernate session can be used within Drools. I want the other way round. Is it possible to query the database using Drools alone? or Drools + Hibernate combination would be fine or Hibernate alone. Please guide. Is Drools used "just to use the domain objects queried from Database" or can it be used to query the database? -- View this message in context: http://drools.46999.n3.nabble.com/Drools-Hibernate-tp4023709.html Sent from the Drools: Developer (committer) mailing list mailing list archive at Nabble.com. _______________________________________________ rules-dev mailing lis</pre> Roopa 2013-05-07T15:09:20 http://comments.gmane.org/gmane.comp.java.drools.devel/6301 <pre>Hi all, I am looking at using the Matrix style decision tables. There is not a lot of documentation on these, but I have also found the spring config for them is lacking. There is a test case here - https://github.com/droolsjbpm/drools/blob/master/drools-decisiontables/src/test/java/org/drools/decisiontable/SpreadsheetCompilerUnitTest.java that shows really that it complies to a DRL. The method call for building the compiler SpreadsheetCompiler.compile() takes an extra argument .. a spreadsheet listener. final SpreadsheetCompiler converter = new SpreadsheetCompiler(); final String drl = converter.compile( stream, InputType.XLS, new RuleMatrixSheetListener() ); But the Spring configuration doesn't seem to support that type.. (i.e. looking at the code in the UnitTest, a "RuleMatrixSheetListener" is passed to the compile. but the spring config won't support tat extra listener. &lt;drools-spring:kb</pre> Ramon Buckland 2013-05-07T13:01:03 http://comments.gmane.org/gmane.comp.java.drools.devel/6300 <pre>Hi Toni, Jervis, I've started the split of Drools Workbench, Guvnor and shared components. I've moved the following to guvor/drools-wb:- - drools-wb-webapp, - drools-wb-distribution, - drools-wb-distribution-wars - drools-wb-docs - drools-wb-examples - drools-wb-jcr2vfs-migation I have updated the POMs and GAVs for these items I am doing some testing of drools-wb-webapp (both hosted and Wildfly\Tomcat distributions) at the moment. I will start to move drools-wb specific editors next. Once they are moved I will update their POMs, GAVs and package names. I hope to move on to the shared components after that. Finally I'll split the guvnor repo into separate ones for drools-wb, guvnor and kie-wb-common.

Git merges can be easily identified in the "network" graph in github repo, or by using any other Git client tool, as parallel lines in the branch history. E.g.: https://github.com/droolsjbpm/droolsjbpm-knowledge/network Please note that each and every merge, while not a big problem by itself, increases the risk of overriding code changes (i.e., losing code) as well as increases future maintenance cost. If you want know more about it, feel free to ask, or just trust me on this... :) Git offers an alternative to merges in the form of "rebase". Rebase enables developers to commit code on top of the most recent change in the branch, instead of in parallel to it. It guarantees no code will be lost when doing that, and makes it easier to maintain code in the future. If you don't know how to rebase code, please read one of the many git books/documentation available on line, like: http://git-scm.</pre> Edson Tirelli 2013-04-25T13:59:10 http://comments.gmane.org/gmane.comp.java.drools.devel/6272 <pre>Hi, I have some difficulties to figure out How I could achieve the same as we did in the past using "changeset.xml" &amp; Knowledge API classes but now with Kie : Code is here : https://gist.github.com/cmoulliard/797426c106a53028ebdd Help is welcome : OLD WHICH IS WORKING KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder(); kbuilder.add(ResourceFactory.newClassPathResource("changeset.xml", getClass()), ResourceType.CHANGE_SET); KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase(); kbase.addKnowledgePackages(kbuilder.getKnowledgePackages()); StatefulKnowledgeSession kSession = createKnowledgeSession(kbase); NEW CODE (DOES NOT WORK - packages = null) KieServices ks = KieServices.Factory.get(); KieFileSystem kfs = ks.newKieFileSystem(); Resource res = ResourceFactory.newClassPathResource("changeset.xml",getClass()) .setResourceType(ResourceType.CHANGE_SET); </pre> Charles Moulliard 2013-04-25T07:40:15 http://comments.gmane.org/gmane.comp.java.drools.devel/6269 <pre>Hi Drools devs FYI When running guvnor I get the following error.
