[rules-users] Temporal reasoning with external persistence not working
I am trying to use an external storage for loading and persisting objects.
But when I try a set a temporal reasoning rule it start to fail. The rule,
test code and exception are given below. Please help
// rules file
package foo.externalwm;
global foo.ExternalStorage session;
import foo.externalwm.YUser
import foo.externalwm.Test
declare User
@role(event)
end
declare Contest
@role(event)
end
rule "test"
dialect "java"
when
$c1:Contest() from session.getContestByName("Contest1")
User(this after[0,3m] $c1) from session.getUserByIndex(0)
then
System.out.println("rule fired");
end
// code
public class Test {
public static void main(String[] args) throws Exception {
KnowledgeBaseConfiguration config =
KnowledgeBaseFactory.newKnowledgeBaseConfiguration();
config.setOption( EventProcessingOption.STREAM );
KnowledgeBase k = init(); // read and compile rules done here
final StatefulKnowledgeSession ksession =
k.newStatefulKnowledgeSession();
ExternalStorage session = new ExternalStorage();
ksession.setGlobal("session", session);
ksession.fireAllRules();
}

[rules-users] Entry point stream OutOfMemoryError?
Based upon what I understood from Drools fusion documentation, entry point
stream can source data from file stream, so it could process data in GB's.
Believe me this is not what I found, to my surprise I found out I got -
Exception in thread "main" java.lang.OutOfMemoryError: Java heap space
at
java.util.GregorianCalendar.computeFields(GregorianCalendar.java:2020)
at
java.util.GregorianCalendar.computeFields(GregorianCalendar.java:1996)
at java.util.Calendar.setTimeInMillis(Calendar.java:1109)
at java.util.GregorianCalendar.(GregorianCalendar.java:576)
at java.util.Calendar.createCalendar(Calendar.java:1011)
at java.util.Calendar.getInstance(Calendar.java:948)
at CashFlowTest.main(CashFlowTest.java:66)
I am reading a huge file in while loop, inside this loop object is being
constructed and inserted into entry point stream. Before even rules would
start firing, it goes straight into exception.
Like below-
while ((readLine = bufferedReader.readLine()) != null) {
String transactionType = readLine.substring(13, 14);
String amount = readLine.substring(9, 12);
if ("C".equals(transactionType)) {
CashFlow wCashFlow = new
CashFlow(Calendar.getInstance()
.getTime(), Double.valueOf(amount),
CREDIT, 1);
memoryEntryPoint.insert(wCashFlow);
} else {
CashFlow wCashFlow = new
CashFlow(Calendar.getInstance()
.getTime(), Double.valueOf(amount),
DEBIT, 1);
}
}
Unless I am doing something wrong here, I conclude it entry stream cannot
source GB data?

Re: [rules-users] WorkingMemoryEntryPoint NullpointerException?
I got it, I have to use Entrypoint in my DRL file otherwise it would give
null pointer exception.
I used like this-
rule "Testing EntryPoint"
when
$cf : CashFlow() from entry-point "TransactionStream"
then
System.out.println($cf);
System.out.println("Testing the transaction stream");
end

Hi Kiran Thanks for your response. Can you share how can I send the user response back to the workflow? -- Regards Aman On Wed, Jun 23, 2010 at 9:51 AM, KiranP wrote: > > hello aman, > > according to me using drools rule flow is the best option to go with... > > according to what i get from your specified problem is you want 2 things : > > 1. u need to manage alternate flows using drools (i.e. leads request must > go > to manager etc.) > >ANS : this is fairly simple and can be done using Drools Rule > flow split node > > 2. u need to dynamically generate the web form ( having various options > like > accept,reject,etc and comment field) > > ANS : though drools is mostly not used to generate form but it > can obviously provide you with list(ArrayList) of options depending on the > outgoing nodes of split(i.e. u add a new outgoing node and it will come > into > list) this list then can be used on the form > > i have myself made a (java+drools+spring+jpa) project for leve application > using the config above > > the following is my rule flow file have a look at it > > > http://drools-java-rules-engine.46999.n3.nabble.com/file/n915957/leaveflow.jpg > > - > Keep Working >> > KiranP > -- > View this message in context: > http://drools-java-rules-engine.46999.n3.nabble.com/How-to-manage-roles-and-generate-web-forms-using-Drools-Flow-tp913725p915957.html > Sent from the Drools - User mailing list archive at Nabble.com. > ___ > rules-users mailing list > rules-users@lists.jboss.org > https://lists.jboss.org/mailman/listinfo/rules-users > ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
[rules-users] How to manage roles and generate web-forms using Drools Flow?
Hi all I am creating a workflow(integrated into a Java web application) for a leave application approval. The workflow is as follows: Leave request is raised for an employee. Case 1: If employee's role is not team lead. The request is sent to employee's team lead. If team lead rejects, workflow ends. If team lead approves, request is forwarded to manager. Case 2: If employee's role is team lead. The request is directly sent to Manager. Workflow ends when manager approves/rejects the application. At the time of approval/rejection the user needs to enter a comment. I need to generate web-form for user input. The options can be dynamic and should be defined in workflow itself. How can I achieve this? What is the right way to manage different directions of a workflow based on different roles? Any thoughts/suggestions are welcome. It will be helpful if someone can direct me to example/sample code to achieve this. -- Regards Aman http://www.IntelliGrape.com ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
