FAIL - getProcessInstances() from persisted StatefulKnowledgeSession

by Anderson Neves

Hi everybody. I configured the session persistence and persisted an instantiated process. When I get the session from the database and use the method getProcessInstances(), it returns an empty collection. But, when I call getProcessInstance(1), and 1 is the InstanceId of the ProcessInstanceInfo (table that contains the process instance), I get the correct process instance. Is this a bug? See the code below. statefulSession = JPAKnowledgeService.loadStatefulKnowledgeSession(sessionId, knowledgeBase, null, environment); Collation<ProcessInstance> processInstances = statefulSession.getProcessInstances(); // FAIL - return empty collection ProcessInstance processInstance = statefulSession.getProcessInstance(1); // OK - return the process instance Regards, Anderson

Problem with CommandFactory.newStartProcess in 5.2 M1

by Seaver, Daniel (GE Healthcare)

There appears to be a problem with CommandFactory.newStartProcess in Drools 5.2 M1. If I do this: String someString = "Some String"; Map<String, Object> variables = new HashMap<String, Object>(); variables.put("someString", someString); List<Command<?>> cmds = new ArrayList<Command<?>>(); cmds.add(CommandFactory.newStartProcess("SampleFlow", variables)); cmds.add(CommandFactory.newFireAllRules()); The default value for the someString variable in SampleFlow does NOT get updated. However, if I do this: String someString = "Some String"; Map<String, Object> variables = new HashMap<String, Object>(); variables.put("someString", someString); List<Command<?>> cmds = new ArrayList<Command<?>>(); StartProcessCommand cmd = new StartProcessCommand(); cmd.setProcessId("SampleFlow"); cmd.setParameters(variables); cmds.add(cmd); cmds.add(CommandFactory.newFireAllRules()); the someString variable does get updated. However, StartProcessCommand is not intended to be used (Discouraged Access), so I don't want to use this solution. Dan

Drools Server : Basic Authentication

by Ross H

Has anyone configured basic authentication on Drools Server. I've setup the web.xml with a security constraint. Testing with a GET on the wsdl works fine. When I POST with a soap message, xstream throws an exception. This seems to be because the camel route with DroolsPolicy is passing the credentials straight through. So it looks as though I have to configure something in the route to handle the credentials and then pass the rest of the message through to DroolsPolicy. -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/Drools-Server-Basic-A...

Drools Introduction Documentation --

by Imaad Ghouri

Hi All, I am a newbie and have just started with drools with documentation: http://downloads.jboss.com/drools/docs/5.1.1.34858.FINAL/drools-introduct... 1). I am at section 3.4 and got the attached exception while I run the maven command: mvn -Declipse -Ddocumentation clean install -DlocalEclipseDrop=/folder/jboss-drools/local-Eclipse-drop-mirror 2). I am new in the community so i appreciate if some one guide me how to start other than drools documentation so I can start in a right fashion. -- Regards, Imaad Ghouri

Decision tables - multiple params to function over multiple columns

by Travis_Smith＠bnz.co.nz

Hi, Currently I've got a consequence on a decision table that works like this: callHelperFunction( $1, $2, $handleFromConditions); where the first two parameters are strings, $1 being a code, $2 a description. which means that you get the table holding things like: "DC X223,This is the description text which can be fairly wordy" That works just fine! However: For ease of maintenance, the risk analysts want the input split over two columns, so is there any way of doing this? I'm trying to avoid inserting a temporary fact then cleaning it up after, if possible, as I can't see that being particularly good for performance.

Drools flow persistence

by DECOUX Yannick

Hi, I'm trying building a simple test case with drools flow (see in attachment). My flow is like this : Start -> print a message -> human task -> print a message The idea of the test is to start the flow and persist the task in the first part. The second part resume the flow using JPAKnowledgeService.loadStatefulKnowledgeSession My project is using h2 for tasks and processes persistence. I'm using a custom human task handler, it basicaly persist the task using the org.drools.task.service.TaskService injected via spring quite like the WSHT implementation without all the client/server stuff It works fine except when a want to assign actorId via a rule. To do that, I'm trying to reuse the assignment.drl and workflow_rules.drl from the drools examples. I red somewhere that i need to set 'drools.advancedProcessRuleIntegration=true' in drools.rulebase.conf to make it work (is that correct ?). When i do that, my workflow doesn't resume and i'm getting this exception : Caused by: java.lang.NullPointerException at org.drools.common.AbstractWorkingMemory.update(AbstractWorkingMemory.java:1372) at org.drools.common.AbstractWorkingMemory.update(AbstractWorkingMemory.java:1338) at org.drools.workflow.instance.node.WorkItemNodeInstance.triggerCompleted(WorkItemNodeInstance.java:199) at org.drools.workflow.instance.node.HumanTaskNodeInstance.triggerCompleted(HumanTaskNodeInstance.java:90) at org.drools.workflow.instance.node.WorkItemNodeInstance.workItemCompleted(WorkItemNodeInstance.java:258) at org.drools.workflow.instance.node.WorkItemNodeInstance.signalEvent(WorkItemNodeInstance.java:234) at org.drools.workflow.instance.impl.WorkflowProcessInstanceImpl.signalEvent(WorkflowProcessInstanceImpl.java:337) at org.drools.persistence.processinstance.JPAWorkItemManager.completeWorkItem(JPAWorkItemManager.java:99) at org.drools.command.runtime.process.CompleteWorkItemCommand.execute(CompleteWorkItemCommand.java:69) at org.drools.command.runtime.process.CompleteWorkItemCommand.execute(CompleteWorkItemCommand.java:34) at org.drools.persistence.session.SingleSessionCommandService.execute(SingleSessionCommandService.java:279) ... 27 more I've attached a simple project using maven/spring/hibernate Am I missing something ? What am I dong wrong ? Thanks for your help

Rule storage

by FrankVhh

Hi all, This may be a stupid question, but is there a way to see your Guvnor-rules outside Guvnor in some kind of readable file? I noticed jackrabbit is used as a repository, so I would like to have a look in there, but I am not able to find it in the expanded guvnor.war folder. The version I am using is Guvnor 5.1.1, with standard configuration. A look in the Guvnor documentation did not help me out. Feel free to burn me if I missed it :-) Thanks and regards, Frank -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/Rule-storage-tp274251...
