I am trying to unmarshal an xml message from JMS that was originally
marshaled using Xstream.
When I create the message I am doing this:
XStream xstream = new XStream(new DomDriver("ISO-8859-1"));
template.sendBody(xstream.toXml(myObject));
On the consuming process I have this in my route:
from(endpoint).unmarshal().xstream().process(myProcessor);
The XStream unmarshal always fails due to non-UTF-8 characters. And the
stacktrace shows that it was a UTF8 reader that failed.
So my question is - is there a way to initialize XStream to use a specific
DomDriver (with an encoding). Or any way to specify the encoding to use by
default?
I tried adding this to the route (right after the from, and before the
unmarshal):
.setProperty(Exchange.CONTENT_ENCODING, constant("iso-8859-1"))
Didn't make a difference.
Here is the stack trace:
