spring - Apache Camel 无效的命名空间处理程序

Question

我有一个在 Eclipse 上开发（重新设计）的应用程序。它在开发环境中运行良好。但是，当它被加载到 Tomcat 中时，它会因命名空间异常而失败：

org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Failed to import bean definitions from relative location [camel-config.xml] 
Offending resource: class path resource [spring-config.xml]; nested exception is org.springframework.beans.factory.BeanDefinitionStoreException: Unexpected exception parsing XML document from class path resource [camel-config.xml]; nested exception is 
org.springframework.beans.FatalBeanException: Invalid NamespaceHandler class [org.apache.camel.spring.handler.CamelNamespaceHandler] for namespace [http://camel.apache.org/schema/spring]: problem with handler class file or dependent class; nested excep
tion is java.lang.NoClassDefFoundError: javax/xml/bind/JAXBException

我的 spring-config 和 camel-config 如下

        <property name="charset" value="iso-8859-1" />

    </bean>

    <camelContext xmlns="http://camel.apache.org/schema/spring"

        <camel:endpoint id="hl7listener"
            uri="mina2:tcp://{{results.endpoint.server}}:{{results.endpoint.port}}?sync=true&amp;codec=#myhl7codec" />
    </camelContext>

    <context:annotation-config />

    <bean class="com.altegix.agent.hl7.HL7ListenerConfiguration" />

我不明白为什么我会收到 InvalidNamespace 异常？还有我以前从未见过的 noClassDefFoundError - 也许我错过了 Eclipse 中的一些类？
