[rules-users] issue in using packages
H i our ruleflow is coupled with a struts2 application. we use guvnor generated pkg files and create knowledgebase out of it and use a caching mechanism to store kbases for reuse. when i create a ksession out of the kbase and start a process , it works for the first time . whenever i try to start the same process second time using the cached kbase, i get the following exception : ERROR - ExceptionInterceptor.publishException(107) | ExceptionInterceptor received exception java.lang.reflect.InvocationTargetException at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) etc ... at weblogic.work.ExecuteThread.execute(ExecuteThread.java:200) at weblogic.work.ExecuteThread.run(ExecuteThread.java:172) Caused by: java.lang.NoSuchMethodError: com.qwest.rx.ruleflow.Process_com_qwest_rx_ruleflow_0.action104(Lorg/drools/spi/ KnowledgeHelper;Lcom/qwest/rx/brain/drools/action/RceHolderUtil;Lorg/drools/spi/ProcessContext;)V at com.qwest.rx.ruleflow.Process_com_qwest_rx_ruleflow_0Action104Invoker.execute(Process_com_qwest_rx_ruleflow_0Action104Invoker.java:21) at org.drools.workflow.instance.impl.ExtendedNodeInstanceImpl.executeAction(ExtendedNodeInstanceImpl.java:66) at org.drools.workflow.instance.impl.ExtendedNodeInstanceImpl.triggerEvent(ExtendedNodeInstanceImpl.java:45) at org.drools.workflow.instance.impl.ExtendedNodeInstanceImpl.internalTrigger(ExtendedNodeInstanceImpl.java:28) at org.drools.workflow.instance.node.StateBasedNodeInstance.internalTrigger(StateBasedNodeInstance.java:31) at org.drools.workflow.instance.node.WorkItemNodeInstance.internalTrigger(WorkItemNodeInstance.java:80) at org.drools.workflow.instance.impl.NodeInstanceImpl.trigger(NodeInstanceImpl.java:112) at org.drools.workflow.instance.impl.NodeInstanceImpl.triggerConnection(NodeInstanceImpl.java:148) at org.drools.workflow.instance.impl.NodeInstanceImpl.triggerCompleted(NodeInstanceImpl.java:135) at org.drools.workflow.instance.node.StartNodeInstance.triggerCompleted(StartNodeInstance.java:49) at org.drools.workflow.instance.node.StartNodeInstance.internalTrigger(StartNodeInstance.java:41) at org.drools.workflow.instance.impl.NodeInstanceImpl.trigger(NodeInstanceImpl.java:112) at org.drools.ruleflow.instance.RuleFlowProcessInstance.internalStart(RuleFlowProcessInstance.java:16) at org.drools.process.instance.impl.ProcessInstanceImpl.start(ProcessInstanceImpl.java:185) at org.drools.workflow.instance.impl.WorkflowProcessInstanceImpl.start(WorkflowProcessInstanceImpl.java:284) at org.drools.common.AbstractWorkingMemory.startProcess(AbstractWorkingMemory.java:1763) at org.drools.common.AbstractWorkingMemory.startProcess(AbstractWorkingMemory.java:1741) at org.drools.impl.StatefulKnowledgeSessionImpl.startProcess(StatefulKnowledgeSessionImpl.java:284) at com.qwest.rx.brain.drools.action.GetNextPageletAction.execute(GetNextPageletAction.java:557) ... 98 more when i try to create the kbase by parsing rf files directly , they are all working fine. the same caching mechanism works well with rf files parsed kbases. any thoughts / suggestions?

Hello All, Was doing some rule writing and am seeing some issues which I want to overcome. In Fusion when we send the facts into working memory.. there seems to be no way that rules are automatically getting triggered. We have to call fireAllRules after each fact insertion. Is this the way it was designed. Its like this in the stocktick example also This one should be simple for somebody with little more experience than me In the following rule rule raise alarm when Event($type : eventType) $events: ArrayList (size 10) from collect (Event(eventType == $type)) then raise alarm In the above rule the raise alarm is getting called 10 times. ..

Re: [rules-users] About fusion and collections
I think something like this should work: rule raise alarm when Event($type : eventType) exists (ArrayList (size 10) from collect (Event(eventType == $type))) then raise alarm Of course that you can't use the $events anymore. You can use a flag too: rule raise alarm when not TheAlarmWasAlreadyTriggered() Event($type : eventType) $events: ArrayList (size 10) from collect (Event(eventType == $type)) then raise alarm insert(new TheAlarmWasAlreadyTriggered()); best, 2010/3/15 Amit Kumar amitku...@gmail.com Hello All, Was doing some rule writing and am seeing some issues which I want to overcome.

Re: [rules-users] About fusion and collections
Amit, Check fireUntilHalt() docs in order to set the engine to reactive mode... although, for most cases I've seen, you still have more control by defining the fireAllRules() cycle explicitly. Regarding your rule, the problem is that the first type is matched for multiple events. The simplest way to fix that is by pre-populating the working memory with all possible event types. In this case you would use a rule like: when EventType( $type : type ) $events: ArrayList (size 10) from collect (Event(eventType == $type)) then // do something end You can also find the distinct event types using accumulate, but that is heavier and more complex than the previous example. Lets say event type is a String: when $types : Set() from accumulate( Event($type : eventType), collectSet( $type ) ) $type : String() from $types $events: ArrayList (size 10) from collect (Event(eventType == $type)) then // do something end I don't really recommend the second approach though. An intermediate approach is to have a separate rule logically insert all event types, and then use the same approach of the first example above: declare EventType type : String @key end when Event( $type : eventType ) then EventType et = new EventType(); et.setType( $type ); logicalInsert( et ); end []s Edson 2010/3/15 Amit Kumar amitku...@gmail.com Hello All, Was doing some rule writing and am seeing some issues which I want to overcome.

Re: [rules-users] OutOfMemoryError with non-existence check in flow XOR split
Heath,
This seems to be caused by an issue in persisting the current rule state
when using a Not rule in a specific combination (and not specifically to
your use of ruleflows). I have opened a JIRA for you and we will fix
this asap.
https://jira.jboss.org/jira/browse/JBRULES-2453
Kris
Quoting heldeen held...@overstock.com:
I am using drools marshalling for persistence and am getting an OOME
with my
simple rule flow. I have a custom CommandService that persists at the
end of
each execution. (I am not using JPA :-( ).
In the rule flow I have a split that checks for the non-existence of
a
simple pojo using not ValidationResult() as one of the constraints.
The
other constraint is ValidationResult(valid == false). I get an
OutOfMemoryError using the not in one of the constraints. Changing
not
ValidationResult() to ValidationResult(valid == true) results in
normal
operation.
The flow is essentially Start-ValidationRuleFlowGroup-XOR
Split-Valid
Action XOR Invalid Action - End. The ValidationRuleFlowGroup has a
simple
set of rules that will insert a ValidationResult() fact if something
is not
valid.
Anyone have any idea why checking for the non-existence of a fact
causes
this error. I'll post the pojo and the stack trace below.
public class ValidationResult {
private boolean isValid;
private String message;
public boolean isValid() {
return isValid;
}
public void setValid(boolean isValid) {
this.isValid = isValid;
}
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}

For example I need enum which does not contain static value like A,B,C rather these A,B,C values come from database. Hi, if the set of allowable enum literals/values is altogether dynamic, this probably cannot be achieved without dynamic bytecode generation (i. e. generate the enum class at runtime). I'm not aware that Drools supports this, you'd probably have to code this on your own. If your database contains a known set of enum values (like A, B, C), you could create an enum with these values and perform string to enum mapping using YourEnumClass.valueOf(nameOfLiteral). If both approaches don't fit your need, you can still stick with ordinary strings. Most of the times I worked with enums in a database, there actually was a finite set of allowable values - sometimes it's hard to find out all the values in this set, but should be doable. Otherwise an enum seems kind of a mis-fit for the problem at hand, because an enum (short for enumeration) actually means the set of values can be enumerated.
