I set up a jms component with spring like this way:
<bean id="jmsConnectionFactory"
class="org.apache.activemq.ActiveMQConnectionFactory">
<property name="brokerURL" value="tcp://localhost:61616" />
</bean>
<bean id="cachedConnectionFactory"
class="org.springframework.jms.connection.CachingConnectionFactory">
<property name="targetConnectionFactory" ref="jmsConnectionFactory"/>
<property name="sessionCacheSize" value="10"/>
<property name="exceptionListener" ref="exceptionListener"/>
</bean>
<bean id="jmsConfig"
class="org.apache.camel.component.jms.JmsConfiguration">
<property name="connectionFactory" ref="cachedConnectionFactory"/>
<property name="concurrentConsumers" value="10"/>
</bean>
I notice that all these 4 beans have exceptionListener property. So I wonder what's the difference setting exceptionListener in different beans.
During my test, only setting in CachingConnectionFactory can work, it can go into my ExceptionListener, while in other cases, the exception will be logged somewhere else, but can't go into my code, the exception is like below.
WARN CachingConnectionFactory.onException(322) - Encountered a JMSException - resetting the underlying JMS Connection

I can't understand how this works, please give some explanation or hint.
org.springframework.jms.connection.CachingConnectionFactory.exceptionListener set the org.apache.activemq.ActiveMQConnectionFactory.exceptionListener , so this is the same.
org.apache.camel.component.jms.JmsConfiguration.exceptionListener set up the org.springframework.jms.listener.AbstractMessageListenerContainer.exceptionListener
Set the JMS ExceptionListener to notify in case of a JMSException
thrown by the registered message listener or the invocation infrastructure.
so it is nearly the same use of that listener at any level but it is better to set it at the org.apache.camel.component.jms.JmsConfiguration.exceptionListener level to be managed by the spring Container.

I am using Apache Camel and camel-amqp component in order to communicate with an ASB queue.

It seems that application uses the same producer for both calls bu the connection to the ASB is closed after 10 minutes.
My question is how can I manage this?
Is there a way to retrieve the producer that was automatically created by Camel, and an OnException part close it and retry again? How can I get the producer?
Thanks a lot!
Problem was solved by modifying cacheLevelName to CACHE_NONE instead of CACHE_CONSUMER.

It is a simple select statement from mysql server and showing output on console. Somehow the result is getting printed in loop though I haven’t used any timer as such.
<beans>
<context:component-scan base-package="com.java"/>
<bean destroy-method="close" class="org.apache.commons.dbcp.BasicDataSource" id="dataSource">
<property value="com.mysql.jdbc.Driver" name="driverClassName"/>
<property value="jdbc:mysql://localhost:3306/world" name="url"/>
<property value="root" name="username"/>
<property value="mysql" name="password"/>
</bean>
<!-- configure the Camel SQL component to use the JDBC data source -->
<bean class="org.apache.camel.component.sql.SqlComponent" id="sql">

<camel:camelContext>
<camel:route>
<camel:from uri="sql:select id from city where countryCode='AFG' and district ='Kabol' "/>
<camel:log message="${body[id]}"/>
<camel:to uri="stream:out"/>
</camel:route>
</camel:camelContext>
</beans>
Client code is:
public static void main(String rgs[]) throws InterruptedException{
PropertyConfigurator.configure("C:/Users/payal.bansal/workspace/CamelOneProject/src/resources/log4j.properties");
//AbstractApplicationContext ctx= new ClassPathXmlApplicationContext("resources/camel-configThree.xml");
AbstractApplicationContext ctx= new ClassPathXmlApplicationContext("resources/camel-configEight.xml");
Thread.sleep(5000);
ctx.close();
}
The from SQL will repeat the SQL call every 500 milli seconds by default (its scheduled).
http://camel.apache.org/sql-component.html
If you want the SQL to fire only once, then use a timer
from timer
to sql
And configure the timer to only run once.

As you can see, the method is wrapped in proxy, still no session found!
The method is run by a scheduler's job, not a controller method, it gets daos etc from spring context. the transaction etc is working good on controller methods, where i'm using #transactional.
Versions: hibernate-4.3.5, spring-4.0.4
Any clue is appreciated.
if you are going to configure your transaction manager as annotation-driven you dont need code below
<tx:advice id="transactionInterceptor" transaction-manager="transactionManager">
<tx:attributes>
<tx:method name="*" propagation="REQUIRES_NEW" rollback-for="Throwable"/>
</tx:attributes>
</tx:advice>
<aop:config>
<aop:advisor pointcut="execution(* com.test.jobs.*.*Job*.*_Execute(..))" advice-ref="transactionInterceptor"/>
</aop:config>
just #Transactional(propagation= Propagation.REQUIRES_NEW) will handle it with
<tx:annotation-driven transaction-manager="transactionManager" />
<bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
<property name="sessionFactory" ref="hibernateSessionFactory"/>
</bean>
However i think you can set (propagation= Propagation.REQUIRES_NEW) only at function level as
#Service
public class SomeService{
#Autowired
private DataSource dataSource;
#Transactional(propagation=Propagation.REQUIRES_NEW)
public void useDataSource() {
//save record
}
}
Yesterday I tried to migrate my bundles from ServiceMix 4.4.1 to Fuse ESB Enterprise 7.1.0. Bundles with local transactions work fine, but other ones with XA transaction don't work well. They write continuously tracebacks with the following messages to the log file:

This endpoint is used very easy in the camel context as:
<route id="route">
<from uri="jmstx:queue:somequeue" />
<!-- some logic here -->
</route>
I would be glad if someone can help me to solve this issue. I can provide more deatails if it necessary.
EDIT
It seems that the issue is connected to the JMS connection pool: when I change connection factory to a simple ActiveMQXAConnectionFactory, then the exception disappears.
This is a known problem in the activemq-pool of version 5.7.0 (and most likely earlier versions) and has been reported http://fusesource.com/issues/browse/ENTMQ-441.

Why I'm trying jmsOperations:
I just need to have original JMSPriority maintained. Yes I did try preserveQoS explicitQoS [various combinations of enablingetc.. it either sets all priority to 4; or priority remains zero despite setting eg=6 priority]. by creating my own jmsOperations and explictly transfering JMSPriority value.

Can anyone point me to jmsOptions usage in camel?
What Camel version do you use?
You should use a custom messageConverter if you want to map to/from JMS messages yourself.
And the JMSPriority ought to be preserved if you set preserveMessageQos=true.
