There's no setter for the broker property in 3.0-M1. You should be able to set the property by retrieving the broker property from the container using spring and set the policy on it.
<sm:container id="jbi" ..> ... </sm:container> <bean factory-method="getBroker" factory-bean="jbi"> <property name="defaultServiceChooser"> <bean class="org.apache.servicemix.jbi.resolver.RandomChoicePolicy" /> </property> </bean> Or something like that. On 12/13/06, Tom <[EMAIL PROTECTED]> wrote:
Hey Guillaume, Thanks a lot for the information.
