Thanks, Christian. It turned out I do need to have the JAXB objects
implement the Serializable marker interface (like here[1], but I didn't
need toString() as it suggests) if I'm going to be sending them or
reading them from a jms queue. But I don't need Serializable if I'm
using the direct component.
I'll check the soap component next.

Hi Glen,
if you use jaxb then your classes do not have to implement Serializable.
Instead they of course need to be serializeable by jaxb.
Btw. if you want to call a webservice with the jaxb object (Seems so as you add
the soap by using xslt) then you should take a look at the camel soap
dataformat. http://camel.apache.org/soap.html

Betreff: Re: Sending POJOs on Message Queues?
But, just to confirm, do I need to make the JAXB objects serializable if
I plan on placing them on a queue or reading them from a queue? If
that's the case (makes sense), I will update the Camel JAXB page to
highlight that--it presently doesn't say anything about serializability.
I'm trying to practice working with JAXB, e.g.,
from(jms:queue:numbersToDouble)
.marshal(jaxbFormat)
.to(xslt://AddSOAPEnvelope.xsl)
.to(CXF_URI)
One more thing--if I needed to make the JAXB object serializable for it
to work on a queue but didn't (or couldn't) do so, what could I replace
from(jms:queue:numbersToDouble) above with to start the route? The
direct component?
Thanks,
Glen

Hi Glen,
Using Camel, you can use marshal() or unmarshal() to transform objects --
XML or XML -- objects

Oh! I was thinking of sending the POJO to the queue where it would be
subsequently read and marshalled into XML, but I can have the client-side
marshal into XML and send the XML to the queue instead. Makes sense...
Thanks again,

No, it's not serializable, but I believe with some effort I can make
it so (The class is JAXB-generated to support a web service call;
JAXB has some extensions to allow for serializability). Right now I'm
trying to get the JAXB DataFormat to work (after sending the object to
the queue I plan on marshalling it to XML) just for the sake of seeing
JAXB working.
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = , propOrder = {
numberToDouble
})
@XmlRootElement(name = DoubleIt)
public class DoubleIt {
protected int numberToDouble;
... setter and getter for above...
}
I can look into JSON and/or Protobuf next -- is it primarily speed, or
ease-of-use (don't have to worry about making the class serializable),
or smaller message size that you recommend those other formats?
In my experience using a format that is not dependent on both the client
and server having the same version of the java object class makes it far
easier to do updates and deployments. If you got an xml format that
works that may fit the bill just fine.
Another bonus is that you can use other languages to process the objects
if needed.

Hello, I'm new to ActiveMQ messaging queues and unsure if I can place

Strings to work it's just using POJO's that is creating the problem

You should be able to send Serializable objects through the queues, but
I would like to suggest you look into other serialization methods like
Protobufs or JSON.
Is DoubleIt serializable?
