我安装了最新的JBoss AS 7(7.0.2)并安装了eclipse工具以将其与WTP连接.我创建了一个"动态Web项目"(没有maven).我试着让"HelloWorld"运行.只有两个班级.
@WebServlet("/HelloWorld")
public class HelloWorldServlet extends HttpServlet {
@Inject
HelloService helloService;
@Override
protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
PrintWriter writer = resp.getWriter();
writer.println("<html><head /><body>");
writer.println("<h1>" + helloService.createHelloMessage("World") + "</h1>");
writer.println("</body></html>");
writer.close();
}
}
public class HelloService {
public String createHelloMessage(String name) {
return "Hello " + name + "!";
}
}
我从eclipse启动服务器,它启动没有错误.但是当从浏览器调用我的servlet(localhost:8080)时,我的代码会抛出一个NPE.
10:28:29,646 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[default-host].[/hello].[hello.HelloWorldServlet]] (http--127.0.0.1-8080-1) Servlet.service() for servlet hello.HelloWorldServlet threw exception: java.lang.NullPointerException

似乎@Inject注释不起作用.如何追查问题？可能是什么原因？
我目前正在开发一个应用程序,它具有基于JBoss 7.1上的JavaEE 6.0的服务器部分和基于Eclipse RCP 3.7的客户端.
对于共享API的简单OSGi包,由于版本和depdencenies的一些差异,我已经遇到了麻烦.对于bundle激活器, API需要" org.osgi.framework. ",对于slf4j日志API ,API需要" org.slf4j. ".
目前我的客户端工作得很好,但JBoss告诉我OSGi导入的预期版本以及slf4j的导入不适合...
我有最佳实践在Eclipse和JBoss之间共享OSGi包吗？我是否需要回到简单的导入和导出声明,或者我能以某种方式使用Require-Bundle吗？我是否需要为JBoss创建一些兼容包以使其运行？在这里进行的最佳方式是什么？
更新 我通过使用Import-Package专门解决了这个问题.对于像org.osgi.framework这样的依赖是使用version ="0.0"来解释它并不重要.:-(这不是很安全,但目前我没有看到另一种选择.有更好的方法吗？
更新2 还需要注意实现OSGi框架的正确版本.JBoss 7.1.x仅实现了OSGi 4.2,它不支持类型安全服务检索.
我需要在应用程序中实现集群机制。这样做时启动jbossAS7时出现错误，错误是：

@Inject
private JAXRSImpl jaxRsImpl;
@POST
@Path("/authenticate")
@Consumes(MediaType.APPLICATION_JSON)
public Response authenticate(Credentials user) {
return jaxRsImpl.authenticate(user);
}
}
而我打算注入的课程是
@RequestScoped
public class JAXRSImpl {
public Response authenticate(Credentials user) {
// Some logic
}
}

public JAXRSInitializer() {
singletons.add(new JAXRSService());
classes.add(JAXRSImpl.class);
}
@Override
public Set<Class<?>> getClasses() {
return classes;
