Hello All,
i need help on understanding, what happens when i stop a running (& fully
functioning) route and start it up again.
I use Camel 2.2 w Spring Configured in a webapp and WAS 6.1 on a Java 1.5
jdk and WebSphere MQ 7.
The root of the problem seems to be a classnotfoundexception of the
object-class that is put as a serialized Object on the Queue.
When i start up my application on WebSphere, it actually works (finds the
class) but after i did stop/start the route it doesn't find the class
anymore: (Sorry my WebSphere speaks german)

Any Idea what happens after stop/start so that my class "disappears"... and
the Broker can't serialize it anymore?
Thanx in Advance,
Martin
