Hi, I am using Apache Camel 1.2.0 and I have the following XML configuration:
<beans xmlns="http://www.springframework.org/schema/beans"; xmlns:ins="http://insurance.com"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd http://activemq.apache.org/camel/schema/spring http://activemq.apache.org/camel/schema/spring/camel-spring.xsd";> <camelContext useJmx="true" xmlns="http://activemq.apache.org/camel/schema/spring";> <route> <from uri="file:inbox"/> <choice> <when> <xpath>//ins:insurance-type='Car'</xpath> <to uri="file:outboxCar"/> </when> <otherwise> <to uri="file:outboxTravel"/> </otherwise> </choice> </route> </camelContext> </beans> I think this XML configuration is correct as it is the same as the XPath explanation on the Camel website. I however get the following exception: 5-nov-2007 18:03:15 org.apache.camel.processor.Logger log SEVERE: Invalid xpath: //ins:insurance-type='Car'.
