Re: xstream usage

Ah-ha!
Solved the mystery.
Apparently you should define -Dfile.encoding=UTF-8 in your activemq.[bat|sh]. IMHO it is a bug, when xstream silently fails to produce output. If it does not like encoding settings, it should throw an exception. 


I already have discovered that this setting in Eclipse prevented me from 
seeing xml output but I decided that it is because body of xml document 
was a byte[] and I had no clue that xml writer will refuse to work with 
non-unicode settings.


Should I file JIRA issue?

Hi

Ah yeah the primitive types in arrays is printed with rather stupid names for 
its classname. You get the X[ stuff that looks as if something is wrong.

Hmmm maybe we can improve Camel here to print a neater name for this ;)

Yesh, that's what I did. As Claus advised I also inserted my own 
Processor to dump additional information. Apparently 
marshall().xstream() returns array of size 0.
Too bad it works fine under Eclipse. I keep digging. Most likely it is 
something with classpath/libraries.



To my surprise (most of my experience is c#) byte[].class.getName() 
returns "[B". At first I thought it is some binary garbage and only 
getCanonicalName clarified the situation :)))

Hi

You could add a process step where you can debug / log out your exchange. And 
100% determine the body type.

It does look like a strange body type? The code does after all just print its 
classname (albeit removing java.lang) for the standard types.

Does it print the body content also? Looks like you cutted the logging short in 
this mail.

Subject: xstream usage

I'm having problems with xstrem. I'm trying to convert jdbc output
into xml and then extract a node I'm interested in.
Host application: activemq-5.1.0
Camel: today's trunk build.
Code:
               from("activemq:vadim33").
               marshal().
               xstream().
               to("activemq:vadim44");

After marshaling I get some strange body "BodyType:[B Body:". I would
expect xml dom object or xml text there.
Any hints what the problem could be?
