How to pass multiple custom objects to processor
I have a wsdl with multiple operations and the typical structure of the
message looks like
<Envelope>
<Header>
<MyHeader>
....
.....
</MyHeader>
<Header>
<Body>
<MyBody>
.........
..........
</MyBody>
<Body>
<Envelope>
Can i unmarshal camel context and send MyHeader and MyBody objects to the
processor in properties or headers?
I do not want to write my custom type converters since there are multiple
"types" of MyBody (because there are multiple operations)
Currently, i have managed to make it work as following
public void myMethod(Exchange exchange,@XPath(//MyHeader) DOMNodeList
header, @Xpath(//MyBody mybody)
-- Do unmarshalling
-- Edit the message
-- Marshal
-- Set Body in outgoing exhange
Is this the right way to do it?

Thanks Matt.
<setProperty propertyName="bodyPart">
<xpath resultType="javax.xml.transform.Source">//MyXpath</xpath>
</setProperty>
And the corresponding getter i.e exchange.getProperties().get("bodyPart")
gives me null. Same with Result.

Hi,
As I don't know your data structure, it's difficult for me to give you a
specific (or "best") way.
But you have 2 possibilities (see http://camel.apache.org/aggregator.html)
:
1. Use a custom aggregation strategy in java code
2. Use the option "grouped exchanges" or use a "custom aggregation
strategy"
Find the solution that suits to your needs.

Thanks arnaudeprez.
This sounds like that this could work.
1. Splitting - i understand , i can unmarshal header and body via xpath
separately and i am good.
Any specific way to collect these two objects and in collection ? And, if i
manage to put my two objects in a collection, in what format should i send
it to processor.
Thanks again!!

If I get you correctly, I think the best pattern that matches your need is
:
1. split your messages by headers and bodies (by using XPath or the
tokenizer with regex expression)
2. then aggregate it in the object you want (a collection or whatever
you want)
3. then call a processor with your result
In my opinion, when I see your process, I have the feeling that you
reinvent the wheel and you did by hand what camel can do for you.

If you're using XPath, couldn't you convert to Source or Result? Both from
javax.xml.transform.

Hi,
you can something like
Assuming JAXB
DataFormat jaxbDataFormat = new
JaxbDataFormat(ObjectFactory.class.getPackage().getName());
where ObjectFactory will be in your generated classes.
.from("direct:start")
.unmarshal(jaxbDataFormat)
.process(new SomeProcessor())
.end();
Similarly you can marshal back.
Checkout the link below Camel Data Format
<http://camel.apache.org/data-format.html>
