我在使用 OSGi 作为 Maven 项目的示例时遇到问题。
NetBeans：http://netbeans.org/kb/docs/javaee/maven -osgi-declarativeservices.html 或者有一个非 Netbeans 版本会产生相同的结果(blogs.oracle.com/arungupta/entry/totd_124_osgi_declarative_services)
我尝试在两个不同的平台 OSX/windows 上查看两组指令，但总是遇到同样的问题。我一直在部署到稳定的 glassfish 3.1。
我已经压缩了我在一次尝试中创建的项目，可以在这里找到它们： https://infra01.gimi.ox.ac.uk:8443/~douglas/problems/OSGiMavenProblem-20110616.zip
与说明相比，我所做的唯一更改是发现我必须将 org.apache.felix.scr.annotations 依赖项更改为 1.4，因为：
执行目标失败
org.apache.felix:maven-scr-plugin:1.7.0:scr
(生成-scr-scrdescriptor) 上
项目helloservice：请使用
org.apache.felix:org.apache.felix.scr.annotations
版本 1.4.0 或更高版本。
一切似乎都按计划进行，直到最后。我部署了 Web 客户端应用程序，但遇到注入问题：
HTTP 状态 500 -

从满足这个要求。

I'm having a problem with an example of OSGi as a maven project.
NetBeans: http://netbeans.org/kb/docs/javaee/maven-osgi-declarativeservices.html or there is a non-Netbeans version which yields identical results (blogs.oracle.com/arungupta/entry/totd_124_osgi_declarative_services)
I've tried going through both sets of instructions on two different platforms OSX/windows and I always end up with the same problem. I've been deploying to stable glassfish 3.1.
I've zipped up my projects that I created in one of my attempts and they can be found here: https://infra01.gimi.ox.ac.uk:8443/~douglas/problems/OSGiMavenProblem-20110616.zip
The only change I've made compared to the instructions is that I found I have to change the org.apache.felix.scr.annotations dependency to 1.4 because of:
Failed to execute goal
org.apache.felix:maven-scr-plugin:1.7.0:scr
(generate-scr-scrdescriptor) on
project helloservice: Please use
org.apache.felix:org.apache.felix.scr.annotations
version 1.4.0 or newer.
All seems to go according to plan until the very end. I deploy the Web Client Application, but I get an injection problem:
HTTP Status 500 -

Any suggestions would be much appreciated as I'm really stuck in my tracks at the moment.
