我正试图在Android上的Jetty上运行Jersey.

我创建了一个用Jersey Servlet实例化Jetty服务器的Android.
无论如何,当我启动Jetty并访问REST资源(在我的情况下：http：//192.168.1.12：8080 / api / hello)时,我收到一条带有消息的ContainerException：没有WebApplication提供程序(请参阅下面的异常堆栈跟踪).

知道为什么吗？

我已经将javax包JNDI添加到项目中,因为它是Jetty或Jersey所要求的. Android不喜欢imporitng javax库所以我暂时使用–core-library命令行参数来编译dex文件.

活动代码：

public class StartServerActivity extends Activity {

private Server webServer;
private final static String LOG_TAG = "Jetty";

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.main);

    System.setProperty("java.net.preferIPv4Stack", "true");
    System.setProperty("java.net.preferIPv6Addresses", "false");

    webServer = new Server(8080);

    ServletHolder servletHolder = new ServletHolder(ServletContainer.class);
    servletHolder.setInitParameter("com.sun.jersey.config.property.packages", "com.famenu.server.resources");
    servletHolder.setInitParameter("com.sun.jersey.config.property.resourceConfigClass", "com.sun.jersey.api.core.PackagesResourceConfig");
    ServletContextHandler servletContextHandler = new ServletContextHandler(webServer, "/api");
    servletContextHandler.addServlet(servletHolder, "/");


    webServer.setHandler(servletContextHandler);

    try {
        webServer.start();
        webServer.join();
        Log.d(LOG_TAG, "started Web server");

    }
    catch (Exception e) {
        Log.d(LOG_TAG, "unexpected exception starting Web server: " + e);
    }
}

}

我正在使用Jetty 7.3.0.v20110203,Jersey 1.12,Android 1.6

解决方法:

WebApplicationProviderImpl通过jersey-server.jar中的META-INF / services条目注册.您是否有机会将泽西岛重新包装到您自己的罐子中而错过了META-INF /服务条目？

因此,要解决此异常,需要将来自jersey-core jersey-server和jersey-servlet的META-INF / services文件夹添加到apk的META-INF文件夹中.

然后您将无法使用Eclipse进行部署,但以下命令行将起作用：

cd PROJECT_DIRECTORY

蚂蚁调试

adb install -r“bin / YOUR_PROJECT-debug.apk”
