Bean binding @Body and Exchange
Hi,
I have the following camel route (defined in blueprint)
In the method "createXML(Exchange exchange)", I create a Document
(org.w3c.dom.Document) and set it as a exchange Body as follows:
exchange.getIn().setBody(doc);
Accessing the Document element in the subsequent method "printXML(Exchange
exchange)" via
Document xmlDoc = (Document) exchange.getIn().getBody();
does not work as I get the exception "java.lang.AbstractMethodError" as soon
as I drop a file in the dropBox. But if I change the method signature to
"printXML(@Body Document xmlDoc)"
I can retrieve the Document element without any issues. My question would
be,
1. what is the difference, retrieving the Body via annotation (@Body) and
via "exchange.getIn().getBody()"
2. If I use @Body annotation, how can access the 'exchange' inside
'printXML' as I need to set the body of the outgoing message.
Please share your comments.
regards,

Karaf / OSGi is a very modular and dynamic platform. And when you use
bean references then OSGi blueprint will proxy communication with
these beans. And I guess something in there got mixed up. As those
beans are from another bundle (I assume) then it may help refresh /
restart those bundles. Or the Karaf container itself.

Dear Claus Ibsen,
The issue got resolved. But it is unclear how it got fixed. I did few things
(see below) and I am not sure which one did the trick.
re-built the osgi-bundles that provided services (createXML and printXML)
Executed osgi:refresh (karaf@root> osgi:refresh)
restarted karaf
and I cannot reproduce the exception anymore. May be you have an idea.
thank you for time,
Rakesh

Hi
Can you post the stacktrace. And what version of Camel are you using?
And what JDK.
