Hi all,
I'm using camel inside servicemix to process some files and I can't
get the freemarker component to work propperly with XML content. Here's what
I did:
I created a processor to convert the body of the exchange message
from String to NodeModel. If I then use freemarker right in the processor to
apply the template it all works fine. But if I pass it along to the
camel-freemarker component the exception you can see below.
Is there an example somewhere of how to do this ? I expected this to
be a fairly comon usecase but I can't seem to find mutch about it.
