please ignor the above post. Some xml tags are deleted. the following is the correct one:
i am developing an Event Driven architecture using j2ee (MDB) on JBoss. In this Architecture the incoming business events (raw events) will be fetched by a MDB, wich forward the raw events to Event Stream Processor. My Problem is that JBoss instantiate multiple instances of my MDB. It means the same event will be delivered repeatedly. I just tried to force JBoss to limit the number of MDB instances. But it was useless. My jboss.xml look like this: | <?xml version="1.0"?> | <!DOCTYPE jboss PUBLIC | "-//JBoss//DTD JBOSS 3.2//EN" | "http://www.jboss.org/j2ee/dtd/jboss_3_2.dtd";> | <!-- The jboss.xml descriptor for the jrmp-comp.jar ejb unit --> | <jboss> | <enterprise-beans> | <message-driven> | <ejb-name>EventInputAdapterBean</ejb-name> | <destination-jndi-name>topic/rawEventTopic</destination-jndi-name> | <configuration-name>Standard Message Driven Bean</configuration-name> | | <invoker-bindings> | <invoker> | <invoker-proxy-binding-name>event-message-driven-bean</invoker-proxy-binding-name> | </invoker> | </invoker-bindings> | </message-driven> | <message-driven> | <ejb-name>ComplexEventInputAdapterBean</ejb-name> | <destination-jndi-name>topic/complexEventTopic</destination-jndi-name> | <configuration-name>Standard Message Driven Bean</configuration-name> | <invoker-bindings> | <invoker> | <invoker-proxy-binding-name>event-message-driven-bean</invoker-proxy-binding-name> | </invoker> | </invoker-bindings> | </message-driven> | </enterprise-beans> | | <invoker-proxy-bindings> | <invoker-proxy-binding> | <name>event-message-driven-bean</name> | <invoker-mbean>default</invoker-mbean> | <proxy-factory>org.jboss.ejb.plugins.jms.JMSContainerInvoker</proxy-factory> | <proxy-factory-config> | <JMSProviderAdapterJNDI>DefaultJMSProvider</JMSProviderAdapterJNDI> | <ServerSessionPoolFactoryJNDI>StdJMSPool</ServerSessionPoolFactoryJNDI> | <MaximumSize>1</MaximumSize> | <MaxMessages>1</MaxMessages> | <MDBConfig> | <ReconnectIntervalSec>10</ReconnectIntervalSec> | <DLQConfig> | <DestinationQueue>queue/DLQ</DestinationQueue> | <MaxTimesRedelivered>10</MaxTimesRedelivered> | <TimeToLive>0</TimeToLive> | </DLQConfig> | </MDBConfig> | </proxy-factory-config> | </invoker-proxy-binding> | </invoker-proxy-bindings> | | </jboss> | i also made some changes in conf/jbossstandard.xml.
