Claus,
I have tried it first, but there are a lot of ClassNotFoundError problems.
Even though you find the least amount of jars to be copied to the tomcat shared
lib, there are problems when you e.g. call
exchange.getIn().getBody(MyApplicationClass.class).
If the Camel core classes are loaded by a different classloader than the
application classes, the getBody returns null even if the body is not null and
is of the correct type (verified with the debugger).
I am thinking about using RMI or something like that.
