Hi What does your bean look like? > <methodCall bean="router" method="route"/>
I think the issue is that the payload from servicemix is XML and Camel will try to find coerce the payload to the type you have defined in your bean. So you can change the signature to use Exchange as type then there shouldn't take any type conventions place. /Claus Ibsen Apache Camel Committer Blog: http://davsclaus.blogspot.com/ On Thu, Nov 20, 2008 at 9:11 AM, Jackey Ding <[EMAIL PROTECTED]> wrote: > Hi, > > I want to wirte a bean dynamically determine what endpoints will be invoked > when a service is called.
