Hi Claus,

Unfortunately, what you propose does not work. For your information, my
activemq is defined in my camelcontext as a vm queue.

When I use in my route "direct" endpoint instead of "activemq", the object
transformed is well send to the "save" bean.

From("File:///c:/temp")
.unmarshall(jaxb)
.to("direct:input");
=20
2nd part :
>From ("direct.input")
.to("bean:converter)
.to("bean:save");
.to("direct:output");

Regards,

Charles=20
