Yes you send the java.io.File over JMS and that cannot be done by
nature. When you send it over JMS it will be converted to a
javax.jms.BytesMessage, eg Camel will load the file content and send
it as bytes to the JMS queue.
That is why it prints B[ etc. as its a byte array. You can use
body.getClass().getCanonicalName() to display the class name that is
more readable.
And btw you can use the tracer to trace the messages instead of doing
your own system out logger

You got it most done you have the file content as a bytes. Then you
can eg process it.
What kind of framework do you want to use to process a MS Word file?
You might wanna check up which kind of object types it expect the MS
world file to work with.
