Subject Spring/Hibernate and transactions
Date Wed, 01 Dec 2010 21:38:48 GMT
I have a simple route that receives messages, converts them to an
@Entity class and attempts to write the data to a database.  I would
like to use Spring/Hibernate to perform this task along with a
TransactionManager.  I have been reading through the Camel In Action
chapter #9 and following the example.  From what I can tell, I should
be using JDBC, but should there be a different if I want to use Spring
and Hibernate?  In my activemq.xml file I import a file where I have
my camel routes and other beans defined.  In this file I have the
following:

    <bean id="jmsConnectionFactory"
class="org.apache.activemq.ActiveMQConnectionFactory">
        <property name="brokerURL" value="tcp://127.0.0.1:61616" />
    </bean>

    <bean id="activemq"
class="org.apache.activemq.camel.component.ActiveMQComponent">
        <property name="transacted" value="true" />
        <property name="transactionManager" ref="txManager" />
    </bean>

    <bean id="txManager"
class="org.springframework.jms.connection.JmsTransactionManager">
        <property name="connectionFactory" ref="jmsConnectionFactory" />
    </bean>

	<bean name="jms" class="org.apache.camel.component.jms.JmsComponent">
		<property name="connectionFactory" ref="jmsConnectionFactory" />
	</bean>


Just like what is in the book.  In another file I have my
hibernate.cfg.xml file which lists the connection information required
to connect to the database.  When I run my code, the processor that is
performing the database inserts is not throwing errors, but the code
is not getting into the database.  This leads me to believe that the
inserts are happening, but the data is not in the database.  I can
query the data and results come back.  So can someone please help me
as to what I am doing wrong?  Here is a snippet of logging when
ActiveMQ starts up:
