Attachment: Added: server.log Link: Added: This issue is a dependency of JBESB-3011 As far as I can remember we have never done any integration testing with BRMS, nor has it been part of the current requirements. Can you please tell me where you are getting the requirement from? Found JBESB-643 which added it into 4.4. Just out of interest, which version of BRMS are you running? JBESB-643 was done a long time back and there has been no further work to upgrade that integration. Hey Kevin, it's in the ERD, 4.1.19 - BRMS Support The PRD has more details: ====== Delivery of proper version of a rule package via the ruleagent to any ESB node. ESB containers allow for hot deployment/reload of the changed rules without component restart and no loss of transactions/messages. This diagram shows three different ESB nodes, each running unique services that use JBoss Rules. The RuleAgent is responsible for polling the BRMS/Repository and reloading any changed rule packages while the ESB is responsible for insuring no messages are lost during the rule reload. ====== For this purpose I use the BRMS-5.0.1 deployed in EAP-4.3 CP06 We already support that functionality through the current integration. What seems to have been missed in this is the upgrade to another version of BRMS. I am chasing this up through other means at the moment, will update you once we get something. I have downloaded BRMS 5, will go through this and see if there are other issues to be addressed. jar sent to jarek for testing Used the new jar (md5sum): jbossesb-jbrules.jar 128e3a91ddbd8f0924f3f0acde01943b Now it's worse (zipped server log attached), when I run the QS for the first time I get: ====================================== ====================================== 2009-12-02 13:48:44,691 DEBUG [org.jboss.soa.esb.lifecycle.LifecycleResource] (pool-26-thread-1) Creating resource using factory: org.jboss.internal.soa.esb.services.rules.DroolsRuleService$LifecycleRuleBaseFactory@3a6012 with identity ID-7 2009-12-02 13:48:44,691 INFO [org.jboss.internal.soa.esb.services.rules.DroolsRuleService] (pool-26-thread-1) destroying stateful session for ID-7 2009-12-02 13:48:44,691 DEBUG [org.jboss.soa.esb.listeners.message.ActionProcessingPipeline] (pool-26-thread-1) Unexpected exception caught while processing the action pipeline: header: [ To: JMSEpr [ PortReference < <wsa:Address jms:10.16.94.134:1099#queue/quickstart_brms_Request_ESB/>, <wsa:ReferenceProperties jbossesb:java.naming.factory.initial : org.jnp.interfaces.NamingContextFactory/>, <wsa:ReferenceProperties jbossesb:java.naming.provider.url : 10.16.94.134:1099/>, <wsa:ReferenceProperties jbossesb:java.naming.factory.url.pkgs : org.jnp.interfaces/>, <wsa:ReferenceProperties jbossesb:destination-type : queue/>, <wsa:ReferenceProperties jbossesb:destination-name : queue/quickstart_brms_Request_ESB/>, <wsa:ReferenceProperties jbossesb:specification-version : 1.1/>, <wsa:ReferenceProperties jbossesb:connection-factory : ConnectionFactory/>, <wsa:ReferenceProperties jbossesb:persistent : true/>, <wsa:ReferenceProperties jbossesb:acknowledge-mode : AUTO_ACKNOWLEDGE/>, <wsa:ReferenceProperties jbossesb:transacted : false/>, <wsa:ReferenceProperties jbossesb:type : urn:jboss/esb/epr/type/jms/> > ] MessageID: e341b748-e997-4af3-a33c-bd662f498782 RelatesTo: jms:correlationID#e341b748-e997-4af3-a33c-bd662f498782 ] org.jboss.soa.esb.actions.ActionProcessingException: RuleAgent could not get the RuleBase. null at org.jboss.soa.esb.actions.BusinessRulesProcessor.process(BusinessRulesProcessor.java:100) at org.jboss.soa.esb.listeners.message.ActionProcessingPipeline.processPipeline(ActionProcessingPipeline.java:634) at org.jboss.soa.esb.listeners.message.ActionProcessingPipeline.processPipeline(ActionProcessingPipeline.java:586) at org.jboss.soa.esb.listeners.message.ActionProcessingPipeline.process(ActionProcessingPipeline.java:420) at org.jboss.soa.esb.listeners.message.MessageAwareListener$TransactionalRunner.run(MessageAwareListener.java:540) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) at java.lang.Thread.run(Thread.java:619) Caused by: org.jboss.internal.soa.esb.services.rules.RuleServiceException: RuleAgent could not get the RuleBase. null at org.jboss.internal.soa.esb.services.rules.DroolsRuleService.executeStatelessRulesFromRuleAgent(DroolsRuleService.java:247) at org.jboss.internal.soa.esb.services.rules.RuleServiceCallHelper.executeStateless(RuleServiceCallHelper.java:176) at org.jboss.internal.soa.esb.services.rules.RuleServiceCallHelper.executeRulesService(RuleServiceCallHelper.java:160) at org.jboss.soa.esb.actions.BusinessRulesProcessor.executeRulesService(BusinessRulesProcessor.java:111) at org.jboss.soa.esb.actions.BusinessRulesProcessor.process(BusinessRulesProcessor.java:92) ... 7 more Caused by: java.lang.NullPointerException at org.jboss.internal.soa.esb.services.rules.DroolsRuleService.getRuleBaseForRuleAgent(DroolsRuleService.java:829) at org.jboss.internal.soa.esb.services.rules.DroolsRuleService.executeStatelessRulesFromRuleAgent(DroolsRuleService.java:238) ... 11 more 2009-12-02 13:48:44,703 WARN [org.jboss.soa.esb.listeners.message.ActionProcessingPipeline] (pool-26-thread-1) No fault address defined for fault message!
