远程api gae祖先查询

当我用祖先执行查询时，我尝试使用远程api并获得exception。

例外：

查询必须具有与包含的祖先密钥相同的应用程序ID（app）：query.app:’firtsAppId’！= query.ancestor.app:’secondAppId’

其中firtsAppId，secondAppId – 它是我的应用程序ID在’remote’和’client’上的appengine-web.xml

• AppEngine SDK 1.7.4
• Windows 8 x64
• jdk1.6.0_38 x64

代码如下：

RemoteApiOptions options = new RemoteApiOptions().server(appId, 443).credentials(username, password); installer = new RemoteApiInstaller(); installer.install(options); DatastoreService service = DatastoreServiceFactory.getDatastoreService(); Entity parentEntity = new Entity("ParentEntity", 1); parentEntity.setProperty("name", "parent"); Key parentKey = service.put(parentEntity); Entity childEntity = new Entity("ChildEntity", 1, parentKey); childEntity.setProperty("name", "child"); service.put(childEntity); Query q = new Query("ChildEntity").setAncestor(parentKey); Iterable values = DatastoreServiceFactory.getDatastoreService().prepare(q).asIterable(); Iterator i = values.iterator(); while (i.hasNext()) { Entity e = i.next(); //some code } installer.uninstall(); 

堆栈跟踪：

 java.lang.IllegalArgumentException: query must have same application id (app) as the contained ancestor key: query.app:'firtsAppId' != query.ancestor.app:'secondAppId' at com.google.appengine.api.datastore.DatastoreApiHelper.translateError(DatastoreApiHelper.java:33) at com.google.appengine.api.datastore.DatastoreApiHelper$1.convertException(DatastoreApiHelper.java:70) at com.google.appengine.api.utils.FutureWrapper.get(FutureWrapper.java:94) at com.google.appengine.api.utils.FutureWrapper.get(FutureWrapper.java:86) at com.google.appengine.api.datastore.FutureHelper.getInternal(FutureHelper.java:71) at com.google.appengine.api.datastore.FutureHelper.quietGet(FutureHelper.java:32) at com.google.appengine.api.datastore.QueryResultsSourceImpl.peekQueryResultAndIfFirstRecordIndexList(QueryResultsSourceImpl.java:161) at com.google.appengine.api.datastore.QueryResultsSourceImpl.loadMoreEntities(QueryResultsSourceImpl.java:104) at com.google.appengine.api.datastore.QueryResultsSourceImpl.loadMoreEntities(QueryResultsSourceImpl.java:91) at com.google.appengine.api.datastore.QueryResultIteratorImpl.ensureLoaded(QueryResultIteratorImpl.java:142) at com.google.appengine.api.datastore.QueryResultIteratorImpl.hasNext(QueryResultIteratorImpl.java:62) 

上面的代码在本地和部署中都不起作用。
