Spring TypeMismatchException Bug?

[malmit]

I am getting a TypeMismatchException which doesn't seem to make any sense. I am setting a org.springframework.jms.core.JmsTemplate property in a Message-driven Bean that I created with a org.springframework.jms.core.JmsTemplate from my applicationConfiguration.xml file. The error is shown below:

13:42:35,763 ERROR [[/search]] Servlet /search threw load() exception

Here is a piece of my configuration file:
<bean id="jmsXAConnectionFactory" class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName">
<value>java:/JmsXA</value>
</property>
</bean>
<bean id="deliveryModePersistent" class="org.springframework.beans.factory.config.FieldRetr ievingFactoryBean">
<property name="staticField">
<value>javax.jms.DeliveryMode.PERSISTENT</value>
</property>
</bean>
<bean id="jmsTemplate2" class="org.springframework.jms.core.JmsTemplate">
<property name="connectionFactory"><ref bean="jmsXAConnectionFactory"/></property>
<property name="defaultDestination"><ref bean="queue2"/></property>
<property name="deliveryMode"><ref bean="deliveryModePersistent"/></property>
<property name="priority"><value>4</value></property>
<property name="timeToLive"><value>0</value></property>
<property name="explicitQosEnabled"><value>true</value></property>
</bean>
<bean id="mdb1" class="uk.ident1.prototype.mdb1.MDB1Bean">
<property name="jmsTemplate"><ref bean="jmsTemplate2"/></property>
</bean>

Here is the code for my MDB:
package uk.ident1.prototype.mdb1;



import java.util.logging.Level;

import java.util.logging.Logger;



import javax.jms.Connection;

import javax.jms.ConnectionFactory;

import javax.jms.DeliveryMode;

import javax.jms.Destination;

import javax.jms.JMSException;

import javax.jms.MessageListener;

import javax.jms.Message;

import javax.jms.MessageProducer;

import javax.jms.ObjectMessage;

import javax.jms.Session;

import javax.naming.InitialContext;

import javax.ejb.MessageDrivenBean;

import javax.ejb.MessageDrivenContext;



import org.springframework.context.access.ContextSingleto nBeanFactoryLocator;

import org.springframework.context.support.ClassPathXmlAp plicationContext;

import org.springframework.ejb.support.AbstractJmsMessage DrivenBean;

import org.springframework.jms.core.JmsTemplate;



import uk.ident1.prototype.db.PrototypeDataAccessHibernat eImpl;

import uk.ident1.prototype.sei.Demographics;



public class MDB1Bean extends AbstractJmsMessageDrivenBean implements MessageListener

{

private static Logger log = Logger.getLogger(MDB1Bean.class.getName());

private PrototypeDataAccessHibernateImpl da = null;

private JmsTemplate jmsTemplate = null;



protected void onEjbCreate()

{

da = (PrototypeDataAccessHibernateImpl)getBeanFactory() .getBean("umTarget");

jmsTemplate = (JmsTemplate)getBeanFactory().getBean("jmsTemplate2");

}



public void setDataAccess(PrototypeDataAccessHibernateImpl da)

{

this.da = da;

}



/**

* Sets the Spring jmsTemplate to integrate the MDB with the Spring Framework

* @param jmsTemplate

*/

public void setJmsTemplate(JmsTemplate jmsTemplate)

{

this.jmsTemplate = jmsTemplate;

}



public void onMessage(Message m)

{

ObjectMessage idMsg = (ObjectMessage) m;

try

{

Long l = (Long)idMsg.getObject();

Demographics d = da.getDemographic(new Integer(l.intValue()));

log.info("Received message containing id: " + d.getId());

log.info(d.toString());

jmsTemplate.convertAndSend(l);

}

catch (Exception e)

{

log.log(Level.SEVERE, "onMessage(): failed to process message!", e);

}

}

}

Is this a bug or am I doing something wrong? If so, does anyone have any suggestions on how to fix this?

Thanks in advanced!

It looks like you have two versions of the JMS classes on your classpath - most likely a jms.jar in your WAR file.
