Question

我使用Scala在Camel和Karaf中创建了一个非常基本的捆绑包。当我在Apache ServiceMix 7.0.0 / Karaf中安装我的软件包时，软件包将解析但无法启动。当我检查日志时，我收到消息：没有找到scheme：jetty

的组件

彻底搜索此问题只会产生答案，指的是确保camel-jetty包含在pom.xml中。

我已经这样做了，但不幸的是它仍然没有工作..

我的Pom依赖项（以及其他）：

    <dependency>
      <groupId>org.apache.camel</groupId>
      <artifactId>camel-jetty-common</artifactId>
      <version>2.16.3</version>
    </dependency>
    <dependency>
      <groupId>org.apache.camel</groupId>
      <artifactId>camel-jetty9</artifactId>
      <version>2.16.3</version>
    </dependency>
    <dependency>
      <groupId>org.apache.camel</groupId>
      <artifactId>camel-jetty</artifactId>
      <version>2.16.3</version>
    </dependency>

Scala中的代码非常基础：

   val netStart = "jetty:http://localhost:8882/userdata"
   val netEnd = "file:scala/netoutput"

   netStart ==> {
    as (classOf[Person])
    to (netEnd)
   }

最后，Karaf Web控制台中显示的引用组件列表是

我已经安装了camel-jetty9功能，作为测试，我在xml中创建了一个蓝图路线，该路线也使用了码头路线，并且工作正常。

为什么ServiceMix / Karaf / Camel坚持要求它找不到码头的任何帮助：html：？

非常感谢！

Answer 1

我们遇到了与此类似的问题，这是由Camel版本和Jetty版本无法协同工作引起的。 Camel尚未更新与Jetty 9一起使用，仅适用于Jetty 8。

如果您回滚到Service Mix 6.1.x，那么您可能会发现问题自行解决，就像在我们的情况下一样。

有关版本控制的详细信息，请参阅http://servicemix.apache.org/community/releases-schedule.html

编辑：Camel 2.18将解决这些问题，但Service Mix 7仅使用2.16

Apache ServiceMix 7，ScalaDSL，没有找到scheme：jetty的组件
