How to create apache camel XA connection using JNDI in Atomikos - jms

Hi i am trying to create a XA transaction for camel and jdbc using atomikos but i have JNDI to set up a XA jdbc transaction i am having issues configuring it.
Below is my code and i am getting cannot write to the class exception

If anyone has worked on apache camel using XA transactions can you guys provide me your sample config file so that i can use and modify it.

This works for me. It looks like you've missed the ActiveMQResourceManager. Also ensure you use a XAPooledConnectionFactory otherwise your MDBs will disconnect after every bind to check for a message (and CPU on the broker will go through the roof).

JMS Message Redelivery not working for Topic in Spring + ActiveMQ + Atomikos + JTA + Tomcat

I have following configuration in the application that works perfectly fine with queues and redelivers the messages when a RuntimeException occurs with transaction rollback as expected.
But the same configuration fails to redeliver message with topics and emits following warning message:
WARN DefaultMessageListenerContainer - Setup of JMS message listener invoker failed for destination 'XXX_TOPIC' - trying to recover. Cause: JTA transaction unexpectedly rolled back (maybe due to a timeout); nested exception is javax.transaction.RollbackException: One or more resources refused to commit (possibly because of a timeout in the resource - see the log for details). This transaction has been rolled back instead.

Apparently it seems that either ContextLoaderListener is initialized more than one time, but where?
The server runs successfully but the attached image is shown in Chrome (browser) and no REST call is running after server startup.
#justin Bertram, HornetQ was working previously and I replaced it with Activemq, and the application is REST base.
Issue is resolved by adding replacing the dependency from
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-aop</artifactId>
<version>3.2.5.RELEASE</version>
</dependency>
to
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-aop</artifactId>
<version>4.3.22.RELEASE</version>
</dependency>
it seems issue was due to conflicting libraries

Camel Transaction Configuration Issue: javax.persistence.TransactionRequiredException

I'm configuring JMS Transactions in Camel 2.10.4 routes. When I run my app, a javax.persistence.TransactionRequiredException: no transaction in progress is thrown. From my research, I found out that this exception is thrown when no method is marked #Transactional. The relevant sections in my application context XML config file is shown:
<bean id="txMgr" class="org.springframework.jms.connection.JmsTransactionManager">
<property name="connectionFactory" ref="pooledConnectionFactory" />
</bean>
<bean id="REQUIRED" class="org.apache.camel.spring.spi.SpringTransactionPolicy">
<property name="transactionManager" ref="txMgr" />
<property name="propagationBehaviorName" value="PROPAGATION_REQUIRED" />
</bean>
<bean id="pooledConnectionFactory"
class="org.apache.activemq.pool.PooledConnectionFactory" init-method="start" destroy-method="stop">
<property name="maxConnections" value="8" />
<property name="connectionFactory" ref="jmsConnectionFactory" />
</bean>
<bean id="jmsConnectionFactory"
class="org.apache.activemq.ActiveMQConnectionFactory">
<property name="brokerURL" value="tcp://localhost:61616" />
</bean>
<bean id="activemq" class="org.apache.activemq.camel.component.ActiveMQComponent">
<property name="configuration" ref="jmsConfig" />
</bean>
<bean id="jmsConfig"
class="org.apache.camel.component.jms.JmsConfiguration">
<property name="connectionFactory" ref="pooledConnectionFactory"/>
<property name="transacted" value="true" />
<property name="transactionManager" ref="txMgr" />
<property name="concurrentConsumers" value="3"/>
</bean>
Besides the JMS-specific configuration, I also have JPA configuration, which is shown below:
<bean id="transactionTemplate" class="org.springframework.transaction.support.TransactionTemplate">
<property name="transactionManager">
<bean class="org.springframework.orm.jpa.JpaTransactionManager">
<property name="entityManagerFactory" ref="entityManagerFactory" />
</bean>
</property>
</bean>
<bean id="jpaTemplate" class="org.springframework.orm.jpa.JpaTemplate">
<property name="entityManagerFactory" ref="entityManagerFactory" />
</bean>
<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalEntityManagerFactoryBean">
<property name="persistenceUnitName" value="fileRecord" />
</bean>
If I disable transactions, the configuration works. When I enable it, however, all the other steps succeeds except the bit where the data is to be inserted into the database (at the JPA endpoint).
Any suggestions on what I need to change or add will be appreciated very much.

EhCache CacheManager with multiple EntityManagerFactory

And one entityManagerFactory in spring-server.xml.
But i must generate one more entityManager, and i do it with
Persistence.createEntityManagerFactory("myotherpersistenceunitname");
but i get exception
Caused by: net.sf.ehcache.CacheException: Another unnamed CacheManager already exists in the same VM. Please provide unique names for each CacheManager in the config or do one of following:
1. Use one of the CacheManager.create() static factory methods to reuse same CacheManager with same name or create one if necessary
2. Shutdown the earlier cacheManager before creating new one with same name.
The source of the existing CacheManager is: DefaultConfigurationSource [ ehcache.xml or ehcache-failsafe.xml ]

The problem, described here, and fixed in the source is not using the EhCache singleton correctly. The answer depends on which version of spring-context-support AND which version of EhCache you are using. For both, you need to be using EhCache 2.6 or greater:
<dependency>
<groupId>net.sf.ehcache</groupId>
<artifactId>ehcache</artifactId>
<version>2.6.0</version>
</dependency>
Next, determine what to do based on your spring-context-support version:
If using Spring 3.1/3.2
<bean id="ehcache" class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean"
p:shared="true"
p:config-location="classpath:ehcache.xml"/>
If using Spring 4.x
<bean id="ehcache" class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean"
p:shared="false"
P:acceptExisting="true"
p:config-location="classpath:ehcache.xml"/>
Try naming both cacheManagers differently in ehcache.xml
<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
name="ehCacheManager1">
<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
name="ehCacheManager2">
