问题：
在karaf中启动bundle时出错：“通过两个依赖链”
龙哲
我目前正在开发一个camel路由，它从netty4/mllpendpoint读取并将hl7消息存储到amqp队列。
这是我的环境：
- apache-maven-3.3.9
- apache-karaf-4.1.1
- apache-camel-2.18.3
- apache-artemis-2.0.0
这是我的pom.xml

我可以在eclipse中使用“main”类运行该项目，没有问题。但当我将捆绑包部署到Karaf容器时，我遇到了一些问题。
我正在用previus pom生成捆绑罐。xml文件，带有ApacheFelix插件，maven clean packagegoal。
karaf安装是干净的。我只设置了以下内容：
- artemis amqp代理位于同一个karaf容器中
功能：回购添加artemis功能：安装artemis amqp
- 骆驼组件
功能：回购添加camel功能：安装camel-core camel-netty4 camel-amqp camel-hl7
我将jar捆绑包复制到部署文件夹中，并尝试用bundle： start my-bundle启动它，但我得到了以下错误。
Error executing command: Error executing command on bundles:
Error starting bundle 110: Unable to resolve demograficos-bundle [110](R 110.0): missing requirement [demograficos-bundle [110](R 110.0)] osgi.wiring.package; (&(osgi.wiring.package=javax.jms)(version>=1.1.0)(!(version>=2.0.0))) Unresolved requirements: [[demograficos-bundle [110](R 110.0)] osgi.wiring.package; (&(osgi.wiring.package=javax.jms)(version>=1.1.0)(!(version>=2.0.0)))]
我由此了解到，容器中缺少jms实现。
我尝试了特性：安装jms，但现在我得到了以下错误
Error executing command: Error executing command on bundles:

我真的很难理解jar/bundle版本在karaf下是如何协同工作的。
有什么想法吗？也许我应该在pom中更改felix插件。xml

看起来您已经声明了自己的包导出了javax。jms包的版本为1.1，而Artemis依赖于导出javax的捆绑包。jms在2.0版中，请确保您也依赖于2.0版javax。jms版本（因为这是artemis使用的版本），您的问题将消失。
类似资料：

在我的一个捆绑包在Karaf我有一个依赖如下所述：- 然后，我在。创建了捆绑包。我正在使用包装，但在将包裹放入Karaf后。我看到它正在导入库的1.0.1版本。然而，如果我将1.0.3版本的放在一个新的Karaf实例中，一切都会正常工作。下面是我从Karaf web控制台看到的导入：- 同时检查我看到了bundle的1.0.1版本：- 因为我的捆绑包正在挑选dogstatsd客户端的1.0.1版，

我正在学习OSGi框架。我发现捆绑包由。类文件和清单文件。现在假设我有两个包A和B，包B依赖于包A的服务。因此，在编译bundle B时，我必须将Bundle A的服务类保存在bundle B的类路径中，或者必须将它(Bundle A的服务)保存在bundle B中，以便编译器可以编译。现在，如果我们这样做，那么模块化是如何实现的，以及这两个包是如何独立的。请帮帮忙。谢谢

我刚来卡拉夫。我有一个jar有一个类App和一个方法main。当我将jar放入Karaf日志服务控制台时，bundle已启动，但似乎什么也没有发生。（jar）做的第一件事是编写一个简单的数据库，这样我就可以查看它是否正在运行（没有生成日志文件，但应该生成一个）。 这个罐子依赖于许多其他罐子。我们的sysadmin不会在生产服务器上安装Maven。helper jar（比如mysql-connect
