Google App Engine JSP无法部署：java.lang.RuntimeException：无法获取系统Java编译器。请使用JDK，而不是JRE

希望这很简单，但是…除了部署到GAE之外，Eclipse在所有方面的工作都相对不错。

我可以在本地运行我的GAE应用程序，但是当我尝试将其部署到Google时，会收到以下消息：

java.lang.RuntimeException: Cannot get the System Java Compiler. Please use a JDK, not a JRE.

我已将构建路径设置为JDK。

当尝试从多个系统（win7和win8）部署同一项目时，也会发生这种情况，因此我怀疑问题与项目本身有关。这个特定的项目已经存在，并且已经在Google上运行了多年。

有趣的是，此错误仅在我的应用程序中有.jsp文件可供部署时才会显示。如果我删除了jsp文件，则它将正确部署。（有点需要jsp文件）

谢谢

我遇到了同样的问题，在迫使Eclipse在我的SDK目录（Win 7 64位）中使用JRE之后，能够成功部署。要强制Eclipse中使用一个特定的JRE看到
这个。看来Eclipse使用的JVM，应用引擎产生的JVM和appconfig使用的JVM应该都相同。希望这对您的情况也有所帮助。

     </receiver>        
     </application>
 </manifest>

解决方法:

您的活动名称是WifiScan但您已将其声明为.activity_wifi_scan更改它并重试.

更改<活动>要素：

<activity android:name=".WifiScan">
         <intent-filter>
                 <action android:name="android.intent.action.MAIN"></action>
                 <category android:name="android.intent.category.LAUNCHER"></category>
                 <data />
         </intent-filter>
     </activity>

Android java.lang.RuntimeException：无法实例化活动ComponentInfo … java.lang.NullPointerException

出于某种原因,每次尝试启动我的应用程序时,我都会出现以下错误：

Unable to instantiate activity ComponentInfo{com.example.lifeahead/com.example.lifeahead.MainActivity}:java.lang.NullPointerException

我检查了清单文件,并添加了所有活动.

我启动应用程序时使用的唯一方法是：

private void logIn(){
    Button logIn = (Button) findViewById(R.id.login);
    logIn.setonClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            // Todo Auto-generated method stub
            Intent loginIntent = new Intent(MainActivity.this, HomeActivity.class);
            loginIntent.putExtra("cmUN", cmUN);
            loginIntent.putExtra("cmPW", cmPW);
            startActivity(loginIntent);
        }
    });
}

这是onCreate：

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    if (savedInstanceState == null) {
        getSupportFragmentManager().beginTransaction()
                .add(R.id.container, new PlaceholderFragment()).commit();
    }

    logIn();
}

我感谢所有帮助！

解决方法:

stacktrace告诉你

  Button logIn = (Button) findViewById(R.id.login);

findViewById返回的对象为null,因为您拥有的唯一方法是logIn(). findViewById返回null的唯一原因是因为您正在查找不属于当前活动的视图层次结构的视图

主要活动的代码是这样的：

public class MainActivity extends Activity {
    private String TAG = getClass().getSimpleName();

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Thread t= new Thread(){
            public void run(){
                Intent intent=new Intent(getContext(),NotificationsService.class);
                //Intent intent=new Intent("hikoki.services.NotificationsService");
                Log.d(TAG,"sending notificationsService");
                startService(intent);
            }
        };
        t.start();
    }

    protected Context getContext() {    
        return this;
    }
}

NotificationsService代码在这里：

public class NotificationsService extends IntentService{
    private static  int TIME_INTERVAL_MILIS=5000;
    private static final int REFRESH=10;
    private  notificationmanager noteManager;
    private static List<FlightStatusNote> flights= new ArrayList<FlightStatusNote>();

    public NotificationsService(){
        super("NotificationsService"); 
        noteManager= notificationmanager)getSystemService(Context.NOTIFICATION_SERVICE)
    }
}

AndroidManifest是这样的：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="hikoki.services"
    android:versionCode="1"

    </activity>
    <service android:name=".FlightStatusService"></service>
    <service android:enabled="true" android:name=".NotificationsService"></service>
</application>

</manifest>

解决方法

您不能从初始化程序(如您原来的那样)或构造函数(就像您现在一样)调用getSystemService().请覆盖onCreate(),并在那里调用getSystemService().

基本上,直到调用onCreate()(或者更准确地说,直到你从onCreate()调用super.onCreate()之后),服务上的继承方法还没有准备好供您使用.

和这样的错误：

如果活动将数据保存到服务器我命令进度条可以运行,但如果没有这不起作用..我应该怎么做才能解决这个问题？

解决方法

由于您正在使用活动上下文的线程,您可能会收到错误.

您应该使用AsyncTask而不是普通线程.
在AsyncTask中,有一个onPreExecute()和onPostExecute()方法,它们在主线程上执行,并且有一个方法doInBackground()将在后台执行,以便您可以轻松实现长期进程.

你可以参考this example
