新泽西码头上Android上抛出ContainerException：[否WebApplication的供应商是present＆QUOT; [英] Jersey on Jetty on Android throws ContainerException: "No WebApplication provider is present"
问题描述
我想在Android上运行码头新泽西州。
I'm trying to run Jersey on Jetty on Android.
我已经创建了一个实例化一个Servlet的新泽西州一个码头服务器一个Android。
反正当我开始Jetty和访问REST资源（在我的情况： http://192.168.1.12:8080/api/hello ）我得到消息ContainerException：否WebApplication的供应商是present（见下面的异常堆栈跟踪）。
I've created an Android that instantiate a Jetty Server with a Jersey Servlet.
Anyway when I start Jetty and visit a REST resource (in my case: http://192.168.1.12:8080/api/hello) I get a ContainerException with message: No WebApplication provider is present (see exception stack trace below).
任何想法，为什么？
我添加的javax包JNDI来，因为它是要求无论是码头或泽西项目。 Android不喜欢，所以我暂时使用--core库的命令行参数反正编译DEX文件imporitng的javax库。
I've added javax package JNDI to the project since it was required by either Jetty or Jersey. Android doesn't like imporitng javax libraries so I'm temporarily using the --core-library command line parameter to compile the dex files anyway.

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);
}
}
}
我使用码头7.3.0.v20110203，新泽西州1.12，Android 1.6的
I'm using Jetty 7.3.0.v20110203 , Jersey 1.12 , Android 1.6
推荐答案
WebApplicationProviderImpl通过在新泽西州的server.jar META-INF /服务条目登记。任何你重新包装成新泽西州自己的罐子和机会错过了META-INF /服务项目？
WebApplicationProviderImpl is registered through META-INF/services entry in jersey-server.jar. Any chance you are repackaging Jersey into your own jars and missed the META-INF/services entries?
因此，要解决这个例外有必要从球衣核球衣服务器和新泽西州的servlet的META-INF /服务文件夹添加到APK的META-INF文件夹中。
So to solve this exception is necessary to add the META-INF/services folders from jersey-core jersey-server and jersey-servlet to the META-INF folder of the apk.
然后，你将无法使用Eclipse来部署，但下面的命令行可以工作：
Then you won't be able to use Eclipse to deploy but the following command line will work:
CD PROJECT_DIRECTORY
cd PROJECT_DIRECTORY
蚂蚁调试
ADB安装-r斌/ YOUR_PROJECT-debug.apk
adb install -r "bin/YOUR_PROJECT-debug.apk"
