How to use TopicConnectionFactory

[whereur]

I'm new to Spring JMS and i m using it for a IBM MQ. I was given a jndi object of TopicConnectionFactory and follow the example from ibm-developworkers to config like this:


<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//Spring//DTD Bean//EN"
"http://www.springframework.org/dtd/spring-beans.dtd">

</property>

</bean>

<bean id="jmsReceiver" class="JMSReceiver">
<property name="jmsTemplate">
<ref bean="jmsQueueTemplate" />
</property>
</bean>
</beans>

after configed, in my JMSReceiver, i use JMSTemplate in this way:

public void sendMessage(final String text){
jmsTemplate.send(new MessageCreator(){
public Message createMessage(Session session) throws JMSException {
return session.createTextMessage(text);
}});
}

and it throws a Error:

java.lang.AbstractMethodError: com.ibm.mq.jms.MQTopicConnectionFactory.createConn ection()Ljavax/jms/Connection;

i dont know if the AbstractMethodError is the default behavior of TopicConnectionFactory,or just for MQTopicConnectionFactory?
And could someone give me some advise of how to config a TopicConnectionFactory by Spring JMS? Thanks so much~ :)

This is a common JMS gotcha...

http://activemq.org/java.lang.NoSuchMethodError

It could be due to you not having JMS 1.1 on your classpath. Try using JmsTemplate102 instead

:confused: it doesnt effect....... i use the jms.jar from spring 2.0 m1,it should be a
* j2ee/jms.jar
- Java Message Service API 1.1 (java.sun.com/products/jms)

and jar from IBM MQ,also from eclipse to view ConnectionFactory,i saw the method of createConnection(). So it shouldnt be a problem of NoSuchMethod. I guess if it is the MQTopicConnectionFactory, itself will throw a AbstractMethodError when we call createConnection() and will work fine when we call createTopicConnection()

but i'm not sure about that and got no javadoc for MQTopicConnectionFactory.......

[jstrachan]

Are you sure that the MQ jar you have does implement JMS 1.1?

maybe u r right,i will consult out MQ admin in a day or two,and first make out the JMS version MQ implemented.
