Dear All, I'm trying to use remote_api to query and update an entity on datastore. I read the following article and successfully query the data.
http://code.google.com/intl/en/appengine/docs/java/tools/remoteapi.html But the poor thing is, after the query, I would like to update the entity. But it didn't work without any error message. Here is part of my code. Would you plz help to check it?? Thanks!! ======================= public class RemoteApiExample { public static void main(String[] args) throws IOException { String username = System.console().readLine("username: "); String password = new String(System.console().readPassword("password: ")); RemoteApiOptions options = new RemoteApiOptions() .server("9x9tvqa.appspot.com", 443) .credentials(username, password); RemoteApiInstaller installer = new RemoteApiInstaller(); installer.install(options); try { DatastoreService ds = DatastoreServiceFactory.getDatastoreService(); // System.out.println("Key of new entity is " + // ds.put(new Entity("Hello Remote API!"))); // My code is beginning here Key k0 = KeyFactory.createKey("MsoChannel", 7); Entity e0; e0 = ds.get(k0); String langCode = (String) e0.getProperty("langCode"); System.out.println("Key=7, langCode=" + langCode); // <-- this works, langCode="en" System.out.println("Now we are going to modify it to be langCode=\"zh\"..."); e0.setProperty("langCode", "zh"); ds.put(e0); } catch (EntityNotFoundException e) { System.out.println("Exception caught!"); } finally { installer.uninstall(); } } } -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
