Passing several POJOs trough multiple routes
Hi,
I converted data from a file into several POJOs which should be available in
different routes for further processing. I tried to store them in the
message header (implements Serializable) but they are just available within
one route. After passing them to the next they are lost. Do I miss something
here? What is the best practice in this case?
Thank you

Some components don't forward headers. Maybe you are losing header entries on special components.
So instead of searching where you are losing the value, storing as properties, like Claus suggests, seems to be easier.

Cool thanks, this helps!
How would I access this the property via Spring XML?
Processor:
exchange.setProperty("MyProperty", myObject); // assume method
myObject.getName();
Camel.xml:
<log message="{{MyProperty.name}}"/>
This doesn't work.

Thank you guys for your help! Here's a simple example that works for me:
DataToPOJOProcessor:
exchange.setProperty("MyProperty", myObject); // assume method
myObject.getName();
Camel.xml:
<route id="Myroute1">
<from uri="MyQueue:incomingData"/>
<process ref="DataToPOJOProcessor"/>
<to uri="MyQueue:pojo?transferExchange=true"/>
</route>
<route id="Myroute2">
<from uri="MyQueue:pojo"/>
<log message="${property[MyProperty].name}"></log>
<to uri="mock:test"/>
</route>
