ClasspathXMLApplicationContext проблема в apache-servicemix-4.3.0-fuse-00-00

Question

Я следовал примеру в главе 14 книги «Верблюд в действии». Я хочу скрыть промежуточное ПО от бизнес-логики. При разработке с использованием «верблюд: бежать:» все, казалось, работало довольно well.The конфигурационный файл ниже:

<?xml version="1.0" encoding="UTF-8"?> 
<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" 
     xsi:schemaLocation=" 
     http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd 
     http://camel.apache.org/schema/spring http://camel.apache.org/schema/spring/camel-spring.xsd 
"> 
     <!-- camel activemq component to connect to the broker --> 
     <bean id="activemq" class="org.apache.activemq.camel.component.ActiveMQComponent"> 
      <property name="brokerURL" value="tcp://localhost:61616" /> 
     </bean> 

     <!-- the camel client --> 
     <camel:camelContext xmlns="http://camel.apache.org/schema/spring"> 
      <proxy id="StreamProxy" serviceInterface="ird.StockStream.StreamService" 
        serviceUrl="activemq:queue:queueStream" /> 
     </camel:camelContext> 

</beans> 

Потом по требованию его развертывания внутри ServiceMix. Я последовал инструкциям плавких предохранителей и узнал о необходимых шагах. Мне нужно изменить схему боба к (я предполагаю, что)

        serviceUrl="activemq:queue:queueStream" /> 
     </osgi:camelContext> 

</beans> 

Наконец, для того, чтобы использовать прокси в клиенте, я:

AbstractXmlApplicationContext ctx = new ClassPathXmlApplicationContext(
           "classpath:META-INF/spring/camel-client.xml"); 
        streamService=(StreamService) ctx.getBean("StreamProxy"); 

Я получаю следующая ошибка, которую я, похоже, не могу исправить. Я не думаю, что я делаю что-то неправильно здесь, пожалуйста, помогите. Я исчерпал свой поиск, никто, кажется, не может ответить на этот вопрос. Любая помощь здесь ценится. Мой karaf.framework = равноденствие и правильные связки были установлены.

Answer 1

Вы должны не изменить пространство имен. Пространство имен http://camel.apache.org/schema/osgi является @deprecated

И вы должны не использовать Весна для загрузки XML-файла снова.

AbstractXmlApplicationContext ctx = new ClassPathXmlApplicationContext ( "classpath: META-INF/spring/camel-client.xml");

И что вы подразумеваете под клиента? Клиент работает внутри ESB или автономно. Где работает клиент?
