But seeing this exception most of the times whenever we restore the session. For testing - we put the timer delays & periods for 1-2 minutes. This could be the reason? Could someone please help? As you know - its panicking to take this to production like this. -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/761210#761210] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&con...]

I have defined two connectionfactories (one for queue and topic - with different JNDI). This seems to fail in JBoss AS7.1.2 with the following error :- 16:59:45,716 ERROR [org.jboss.msc.service] (MSC service thread 1-6) MSC00002: Invocation of listener "org.jboss.as.connector.deployers.ra.processors.ParsedRaDeplo ymentProcessor$1@7d557ee8" failed: java.lang.IllegalStateException: JBAS014666: Duplicate resource resource-adapters at org.jboss.as.controller.registry.AbstractModelResource$DefaultResourceProvider.register(AbstractModelResource.java:225) [jboss-as-controller-7.1.2.Fina l.jar:7.1.2.Final] at org.jboss.as.controller.registry.AbstractModelResource.registerChild(AbstractModelResource.java:135) [jboss-as-controller-7.1.2.Final.jar:7.1.2.Final] at org.jboss.as.connector.deployers.ra.processors.AbstractResourceAdapterDeploymentServiceListener.transition(AbstractResourceAdapterDeploymentServiceList ener.java:109) [jboss-as-connector-7.1.2.Final.jar:7.1.2.Final] at org.jboss.msc.service.ServiceControllerImpl.invokeListener(ServiceControllerImpl.java:1416) [jboss-msc-1.0.2.GA.jar:1.0.2.GA] at org.jboss.msc.service.ServiceControllerImpl.access$2700(ServiceControllerImpl.java:49) [jboss-msc-1.0.2.GA.jar:1.0.2.GA] at org.jboss.msc.service.ServiceControllerImpl$ListenerTask.run(ServiceControllerImpl.java:1954) [jboss-msc-1.0.2.GA.jar:1.0.2.GA] at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) [rt.jar:1.6.0_30] at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) [rt.jar:1.6.0_30] at java.lang.Thread.run(Thread.java:662) [rt.jar:1.6.0_30] The files I have used are from http://blog.coffeebeans.at/?p=230 http://blog.coffeebeans.at/?p=230 . (I read few responses which asks to pick the nightly build but they were old posts. Is this fix in a newer version after 7.1.2 or a wrong usage ? ) Regards, Aryan -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/761638#761638] Start a new discussion in IronJacamar at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&con...]

Is this really required if I have to deploy a resource adapter in JBoss AS7. What is the advantage of having this file or what if I dont' have this file in the resource adapter, but configure in standalone.xml.

[jBPM] - Using drools in a web app is my approach correct

by gerasalus

gerasalus [https://community.jboss.org/people/gerasalus] created the discussion "Using drools in a web app is my approach correct" To view the discussion, visit: https://community.jboss.org/message/761632#761632 -------------------------------------------------------------- Hi all, some newbie questions. I'm wondering is my thinking and my architecture correct? Preconditions: 1. We have a set of rules stored in DB.Rules will be reloaded from DB only once a day 2. We have a set of meta-facts. Retrieval of those facts is expensive, and they only get updated once a day, after midnight - current meta-facts are immutable for a day. 3. We have user facts - some user specific data which we should be using together with meta-facts and producing output for specific user. 4. Our SLA is 150 req/s. Typical flow would be something like: we have rules together with meta facts. Along comes user with his general facts and request specific facts. For this input we run rules and produce results - calculate some data. Basically a typical quote calculation, just we are not calculating quotes :) Rules may change working memory (cart explosion pattern) So how would i make this work for multi user environment in a spring web apps? My ideas: 1. Create a custom Spring scope that will cache KnowledgeBase and invalidate it once it expires (at the beginning of new day) 2. Cache meta-facts (they are expensive to retrieve) for given time 3. For each user request (user comes in with its own facts) - create a new StatefulKnowledgeSession from existing KnowledgeBase byt inserting meta-facts and user specific facts and execute fireAllRules 4. Retrieve the result and dispose the StatefulKnowledgeSession() As i unserstand, if my rules are modifying working memory, i cannot reuse StatefulKnowledgeSession for different users (as they bring their own facts). Is there a better approach ? By reading forums and mailing lists i have mixed data about StatefulKnowledgeSession creation. There are threads that state cpu spikes while creating sessions. Maybe i should be considering pool of StatefulKnowledgeSession and inserting/retracing user facts while keeping meta-facts? Thanks! -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/761632#761632] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&con...]

BTW you should create a new thread instead of using such old one because the server will be complete different. -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/761608#761608] Start a new discussion in Beginner's Corner at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&con...]
