  1. POGet BeanCreationException when try to add Jackson Library
    text
    copied!<p>I have a simple Hello World example that passes a Map to Camel and displays the values to the console via Log4J. I want to expand this example to render this map in JSON by adding the Jackson library to my Camel applicationContext.xml </p> <p>First I tried adding the following XML tags to my applicationContext.xml (as specified at <a href="http://camel.apache.org/json.html" rel="nofollow">http://camel.apache.org/json.html</a> under "Using JSON in Spring DSL") </p> <pre><code>&lt;camel:dataFormats&gt; &lt;camel:json id="jack" library="Jackson"/&gt; &lt;/camel:dataFormats&gt; </code></pre> <p>But when I add this to my applicationContext.xml, and run my Java code I get the following XmlBeanDefinitionStoreException message: </p> <pre><code>cvc-complex-type.2.4.a: Invalid content was found starting with element 'dataFormats'. One of '{"http://camel.apache.org/schema/ spring":route}' is expected. </code></pre> <p>Moving these tags inside or outside of my camelContext yields the same error (just a longer list of URLs when inside the camelContext). </p> <p>Is there something else I need to specify in my ApplicationContext.xml? </p> <p>Here is my current applicationContext.xml:</p> <p>UPDATED: The following xml now works. Had to move the location of the dataFormats XML tags.</p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:camel="http://camel.apache.org/schema/spring" xmlns:context="http://www.springframework.org/schema/context" xmlns:util="http://www.springframework.org/schema/util" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.0.xsd http://camel.apache.org/schema/spring http://camel.apache.org/schema/spring/camel-spring.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"&gt; &lt;bean class="org.springframework.context.annotation.CommonAnnotationBeanPostProcessor" /&gt; &lt;context:component-scan base-package="sample" /&gt; &lt;context:annotation-config /&gt; &lt;camel:camelContext id="HelloWorldContext"&gt; &lt;camel:dataFormats&gt; &lt;camel:json id="jack" library="Jackson"/&gt; &lt;/camel:dataFormats&gt; &lt;camel:route&gt; &lt;camel:from uri="timer://hello.world.request.timer?fixedRate=true&amp;amp;period=10000" /&gt; &lt;camel:to uri="log:hello.world.request?level=INFO?showAll=true" /&gt; &lt;camel:bean ref="helloWorld" /&gt; &lt;camel:to uri="log:hello.world.response?level=INFO?showAll=true" /&gt; &lt;/camel:route&gt; &lt;/camel:camelContext&gt; &lt;bean id="jms" class="org.apache.activemq.camel.component.ActiveMQComponent"&gt; &lt;property name="configuration" ref="jmsConfig" /&gt; &lt;/bean&gt; &lt;bean id="jmsConfig" class="org.apache.camel.component.jms.JmsConfiguration"&gt; &lt;property name="connectionFactory" ref="jmsConnectionFactory" /&gt; &lt;property name="transacted" value="false" /&gt; &lt;property name="concurrentConsumers" value="1" /&gt; &lt;/bean&gt; &lt;bean id="jmsConnectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory"&gt; &lt;property name="brokerURL" value="vm://localhost" /&gt; &lt;property name="redeliveryPolicy" ref="redeliveryPolicy" /&gt; &lt;property name="prefetchPolicy" ref="prefetchPolicy" /&gt; &lt;/bean&gt; &lt;bean id="prefetchPolicy" class="org.apache.activemq.ActiveMQPrefetchPolicy"&gt; &lt;property name="queuePrefetch" value="5" /&gt; &lt;/bean&gt; &lt;bean id="redeliveryPolicy" class="org.apache.activemq.RedeliveryPolicy"&gt; &lt;property name="maximumRedeliveries" value="1" /&gt; &lt;property name="backOffMultiplier" value="2" /&gt; &lt;property name="initialRedeliveryDelay" value="2000" /&gt; &lt;property name="useExponentialBackOff" value="true" /&gt; &lt;/bean&gt; &lt;/beans&gt; </code></pre>
