I think this is the problem. Documentation looks to me little flawed and it
does not look like a proper JMS implementation.
On one hand it says that ConnectionFactory is imeplemented...
-------------------------------------------------------------------------------------------------------------------
Class JmsTopicConnectionFactory
java.lang.Object
<http://java.sun.com/j2se/1.4.2/docs/api/java/lang/Object.html>
extended by <https://webmail.wipro.com/exchange/resources/inherit.gif>
cgl.narada.jms.JmsTopicConnectionFactory
All Implemented Interfaces:
JmsDebugFlags
<https://webmail.wipro.com/exchange/cgl/narada/jms/JmsDebugFlags.html> ,
ConnectionFactory
<http://java.sun.com/j2ee/1.4/docs/api/javax/jms/ConnectionFactory.html> ,
TopicConnectionFactory
<http://java.sun.com/j2ee/1.4/docs/api/javax/jms/TopicConnectionFactory.html>
-------------------------------------------------------------------------------------------------------------------
Then it mentions about something very strange which I can not make out.
--------------------------------------------------------------------------------------------------------------------------
This class implements the JMS connection factory. What is being done is,
* Intitializer class, is called upon to intialize the IP address and the
port number to which a connection needs to be made.
* This Initializer class then instantiates a connection factory, that is
responsible for open connections to the particular broker. The getConnection()
method requests a TCP socket connection with the broker in question.
-------------------------------------------------------------------------------------
I think this implementation is not as per JMS spec. May be you have to look at
the code and take help from the guys who have implemented it..

Subject: RE: Using jms component with NaradaBrokering
Thanks a lot, your answer helped me to understand much better how this xbean
configuration file work.
I've made the change you told me but there was still the same error, so I
replaced the <property> by <constructor-arg>:
<bean id="jmsFactory" class="cgl.narada.jms.JmsTopicConnectionFactory">
<constructor-arg value="localhost" />
<constructor-arg value="3045" />
<constructor-arg value="tcp" />
</bean>
The compilation and installation work fine with this xbean, but a new error
appear when i try to activate my SU on ServiceMix. Here is the error:
Caused by: java.lang.AbstractMethodError:
cgl.narada.jms.JmsTopicConnectionFactory.createConnection()Ljavax/jms/Connection;
I looked again at the http://www.naradabrokering.org/api/
JmsTopicConnectionFactory API , it's true that this class does not implement
the createConnection method but only the createTopicConnection one. That's
strange because this class implement the
http://java.sun.com/j2ee/1.4/docs/api/javax/jms/ConnectionFactory.html
connectionFactory interface and should implement this method.
Do you think it's the problem ? And what could I do to fix it ?
Thanks.
