Hi
You can configure the jms endpoint with jmsMessageType=Bytes
That tells Camel to force and use a javax.jmx.BytesMessage for the JMS message.
Then you dont need to convert the message beforehand.
And mind about stream caching for big payloads. The http component
forces using that
http://camel.apache.org/stream-caching.html
It overflows to disk when its > 64KB. So I suggest in your case set
set a higher threadshold with
CamelCachedOutputStreamThreshold
So it wont overflow to disk.

Hello Claus,
We are converting the text message into bytes because an issue with
ActiveMQ... ActiveMQ text message have a restriction on payload size
shouldnt be greater than 64K as they use the API DataOutputStream.writeUTF8
which has this restriction. I have logged it on to their forums but not much
help there :( the link for the same is ->
http://activemq.2283324.n4.nabble.com/ActiveMQ-5-8-0-Issue-with-HTTP-Connector-td4664876.html
Let me check with tracer and see i am able to zero down on the isssue here..
Thanks for the pointers claus.. Appreciate it..
Regards.

Use the tracer to see what happens.
http://camel.apache.org/tracer
The type conversion to byte[] should contain some data.
And mind that if you send a bytes jms message, then you cannot often
view that in a JMS console. Its not human readable. If you use a Text
message instead, then you can view the XML in a JMS console.
And why do you want to use byte[] when the data is text based, and a
javax.jms.TextMessage type is a better fit?

Hi Claus.
Thanks for your time..so based on the above route .. i should have seen the
JMS message having the byte payload of the XML but that doesnt happen.
As i understand from the class
https://svn.apache.org/repos/asf/camel/trunk/components/camel-http4/src/main/java/org/apache/camel/component/http4/DefaultHttpBinding.java
it doesnt set the body of the message into exchange hence the JMS message
payload is empty.
Is my understanding right here?
Regards,
-Yogesh

Hi
Yes the servlet component can support any kind of data the servlet
container can handle. eg that is HTTP.
Usually the caller sets the "Content-Type" header with a value of
"text/xml" to tell you that the http body is xml based.
