Mistyped route builder spring configuration - better error description
----------------------------------------------------------------------
Key: CAMEL-1517
URL: https://issues.apache.org/activemq/browse/CAMEL-1517
Project: Apache Camel
Issue Type: Improvement
Affects Versions: 2.0-M1
Reporter: Claus Ibsen
Priority: Minor
Fix For: 2.0.0
If you mistype a route builder ref such as
{code}
<bean id="route"
class="org.apache.camel.itest.tx.JmsToHttpWithOnExceptionRoute"/>
<!-- Camel context -->
<camelContext id="camel" xmlns="http://camel.apache.org/schema/spring";>
<template id="producer"/>
<!--use our route -->
<routeBuilder ref="xxxroute"/>
</camelContext>
{code}
You get a long exception stacktrace that does not hint that bean with id
{{xxxroute}} could not be found
{code}
