How to enable jms flow in two containers

Hi,
I have two servicemix containers running on the same machine.
Also I one ActiveMQ broker and both servicemix containers listens to the
same port in the activemq.I have a client that sends messages and gets back
the exchanges.
But while deploying the same service assembly in two machines I have some
jms flow exception.
I am not sure why I am getting this.
I thought jms flow is default and is required for amq clustering.
I even added one line in servicemix.xml where it says 
flowNames="jms".
I am not sure what else I need to do to resolve this issue?
Anymore configuration ?
Regards,
Yogaraj

The stack trace in your other message was from servicemix startup, I thought
you were saying in this current thread that you were getting an error while
deploying a service assembly so that was why I asked for more information.

Thanks,
Chris

ActiveMQ can handle failover of the broker using the Master/Slave
configuration. See the following document for more info:

http://activemq.apache.org/masterslave.html

But if you want reconnect, you need to change from using the
jms:endpoint to using the jms:consumer in the xbean.xml configuration
file.

Bruce,
Is there a way I can do ActiveMQ clustering as well.
In the present scenario if My ActiveMQ shuts down then the servicemix have
to restart to connect to it.So is there software level of clustering for
both ActiveMQ and Servicemix.
Is it possible to use embedded ActiveMQ cluster in this situation.
If yes what are the configuration I need to make.
Please describe in brief.
Regards,
Yogaraj

The number of containers should only have an effect on performance if
there is some latency between them or if there is an extremely large
amount of them. Unfortunately there is no information about this topic
in the wiki.

This is directly related to the endpoints that are being used as a
result of your configuration for the servicemix-jms component in the
xbean.xml file. If you're using the jms:endoint, this refers to the
endpoints referenced here:

http://servicemix.apache.org/servicemix-jms.html

The jms:endpoint does not support automatic reconnection and is the
problem that you're seeing. To work around this, you will need to
instead use the newer jms:consumer endpoint that is referenced here:

http://servicemix.apache.org/servicemix-jms-new-endpoints.html

The jms:consumer endpoint supports reconnection as well as various
levels of caching the connection, session and consumer. Depending on
the JMS provider you are using, your mileage may vary (YMMV).

Thanks Bruce it was informative for me.
I think I need to enable all the flow then.
Can you please tell me like how does the no of container has effect on
performance and where can I find information about them.
Also if I restart ActiveMQ servicemix containers doesn't seem to connect to
that again unless I start servicemix as well.Can you please post your
opinion on this as well.

The flows do not depend on one another so you can disable the JCA flow
if you don't need it (the JCA flow is the only way to enable
transactionality). It's just that the default ServiceMix configuation
enables SEDA, JMS and JCA.

I think its working now.
but in debug mode I can see both JMS and JCA flow are enabled.
Will it work fine if I disable JCA flow.

Could you post the output with these exceptions and also the
servicemix.xmlfrom both of the machines you are trying to connect via
jmsFlow?
