Description

I am trying CBR pattern and using 'choice', 'when', 'to' and 'endChoice()'.
I can actually have the code compile, but always got cast exception when running it.

this really confused me, because I checked every steps and can't find any problems.
does anyone have similar situation?

here is my Camel route in JDSL:
=========================================================================
18 CamelContext context = new DefaultCamelContext();
19 ConnectionFactory connectionFacotyr = new ActiveMQConnectionFactory("tcp://P10118178-T400:61616");
20 context.addComponent("jms", JmsComponent.jmsComponentAutoAcknowledge(connectionFacotyr));
21
22 context.addRoutes(new RouteBuilder() {
23 public void configure() throws Exception

{ 24 from("jms:incomingOrders") 25 .choice() 26 .when(header("CamelFileName").endsWith(".crt")) 27 .to("jms:crtQueue").endChoice() 28 .when(header("CamelFileName").endsWith(".zpx")) 29 .to("jms:zpxQueue"); 30 }

31 });
=========================================================================

pretty simple route. but always got an 'java.lang.ClassCastException' when I start the Camel route.
the exception message as below: (the exception occurred at line 27)
