I have two questions:
I would like to stream the result of an iterator to a file.
I succeeded in doing that using a split with a factory class that creates my
iterator.
The name of the file is set dynamically in the header of the exchange.
So far I have no problem at all.
But I also want to write

My JNDI solution doesn't seem to work.
It seems as though I get a serialized object from JNDI.
As I start producing messages new connections are created. Instead of
reusing the pooledConnections.
What i did is:
1. created a separate project that registers a
I think i found a solution (still implementing it).
1. Create a war that uses spring to create a amqjndipooledtransactionfactory
2. Inside this use a jndiexporter that can be found on the internet to
export this bean to jndi
3. Inside jboss-web.xml in other wars define a depedency to the war of
Currently we create beans for interacting with activemq in each project.
So a lot of poolConnectionFactories get created.
This creates a lot of connections to activemq and we also must invest a lot
to change this configuration.
The pro to this aproach is that change can be implemented standalone
I was already looking into using JNDI for registering an
AmqJNDIPooledConnectionFactory but I couldn't find out how to register this
using an existing ActiveMQConnectionFactory (spring bean).
Does anybody have an example?

Seems like it would be nice to have a connection
Sorry. I didn't realize that the environment would make such a difference.
We have jboss 5 as and activemq standalone running.
Until now i couldn't find an easy way to register a pooledconnection in jndi
inside jboss as i suppose i need to do.

As a java-developer I think it is very important to migrate when new versions
are released.
Currently we are running camel 2.4.2.
I think that we should migrate to 2.9 or 2.10, but I find it hard to define
a business-case for this.
So sell that migration is neccesary.
How should I support it that
We use camel for hiding our infrastructure, which means that we call one or
more interface methods from java to put messages on a queue.
In our current configuration we do two method calls in one java-method.
Each call puts a message on a queue.

I recall that allthough the classloading in camel 2.8 is resolved in camel
for JBoss that in that version of activemq there still remained an issue
with classloading in the activemq component.
I recall that there was an jira issue created. Can anybody help me to find
it.
This issue is a blocker
Can you explain how the cache level is shared among several war's?
I can not find any static fields that contain this level.
In what class can I find this?

We use Camel 2.4.0 to hide infrastructure. So camel sends an InvocationBean
over JMS.
When an exception is raised we want to enrich the message on the DLQ with
information about the exception being raised.
To do this we configure an onException in spring xml.
If we do nothing in this
I was expecting this reaction.
It doesn't matter.
I've found a solution:
I've made a processor which sets the data on the out of the exchange.

I want to send the same message to two endpoints.
The first one is request/reply and if an exception is raised the message
should not be send to the second endpoint.
How can I send the original message to the second endpoint

Is suppose something like:

xmlns=http://camel.apache.org/schema/spring;
route
from uri=seda:a/
multicast

I would try to solve this by splitting the route in smaller subroutes.
Perhaps you can filter in the subroute.

About the cache level:

Transactions and Cache Levels

the default settings for cache level can impact performance.
