[jboss-user] [JBoss Messaging] - help on JmsXA

[mattlf]

Hi

I am new to jboss messaging and i apologize if my question turns out to be silly.


I have a sender that createConnection, createSession and createProducer on every message. I am concerned this is very inefficient. I read on some other posts that it is acceptable if one uses JmsXA


  | public class JmsPublisher 
  | {
  | 
  | 	private ConnectionFactory bizConnectionFactory ;
  | 	private Destination bizDestination;
  | 
  | 
  | 	public ConnectionFactory getBizConnectionFactory() {
  | 		return bizConnectionFactory;
  | 	}
  | 	public void setBizConnectionFactory(ConnectionFactory bizConnectionFactory) {
  | 		this.bizConnectionFactory = bizConnectionFactory;
  | 	}
  | 	public Destination getBizDestination() {
  | 		return bizDestination;
  | 	}
  | 	public void setBizDestination(Destination bizDestination) {
  | 		this.bizDestination = bizDestination;
  | 	}
  | 
  | 	public JmsPublisher(){}
  | 
  | 	public void sendEvent(SignalAbstract ev) 
  | 	throws
  | 	JMSException
  | 	{
  | 		Connection connection = null;
  | 		Session session = null;
  | 		MessageProducer messageProducer = null;
  | 
  | 		try 
  | 		{
  | 
  | 			connection = bizConnectionFactory.createConnection();
  | 			session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
  | 			messageProducer = session.createProducer(bizDestination);
  | 
  | 			ObjectMessage msg = session.createObjectMessage(ev);
  | 
  | 			messageProducer.send(msg);
  | 
  | 		} 
  | 		finally 
  | 		{
  | 			if (messageProducer != null) try { messageProducer.close(); } catch (Exception ignore) { }
  | 			if (session != null) try { session.close(); } catch (Exception ignore) { }
  | 			if (connection != null) try { connection.close(); } catch (Exception ignore) { }
  | 
  | 		}
  | 
  | 	}
  | 
  | }
  | 


I inject the jndi name via Spring


  | 	<jee:jndi-lookup id="bizConnectionFactory"
  | 		jndi-name="${biz.messagingConnectionFactoryName}">
  | 		<jee:environment>
  | 			java.naming.provider.url=${biz.messagingProviderUrl}
  | 			java.naming.factory.url.pkgs=org.jnp.interfaces:org.jboss.naming
  | 			java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
  | 		</jee:environment>
  | 	</jee:jndi-lookup>
  | 
  | 	<jee:jndi-lookup id="bizDestination"
  | 		jndi-name="${biz.messagingDestinationName}">
  | 		<jee:environment>
  | 			java.naming.provider.url=${biz.messagingProviderUrl}
  | 			java.naming.factory.url.pkgs=org.jnp.interfaces:org.jboss.naming
  | 			java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
  | 		</jee:environment>
  | 	</jee:jndi-lookup>
  | 
  | 	<bean class="com.strateer.biz.impl.JmsPublisher"
  | 		id="bizJmsPublisher">
  | 		<property name="bizConnectionFactory" ref="bizConnectionFactory" />
  | 		<property name="bizDestination" ref="bizDestination" />
  | 	</bean>
  |  

It works when


  | biz.messagingProviderUrl=localhost:1099
  | biz.messagingConnectionFactoryName=ConnectionFactory
  | 

but it doesn't when i change the connectionFactoryName to java:/JmsXA


  | biz.messagingProviderUrl=localhost:1099
  | biz.messagingConnectionFactoryName=java:/JmsXA 
  | 


The logs say the following:
Error creating bean with name 'bizConnectionFactory': Invocation of init method failed; nested exception is javax.naming.NameNotFoundException: JmsXA

And i don't seem to be able to get it working.

I would appreciate some tips

Thank you for your help

matt
