Google App Engine for Java のコードがローカルホストで動かない。
Google App Engineのチュートリアルをほぼそのままコピーして下記のようなコードを書きました。
package com.example.appengine.helloworld;
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.util.Date;
import com.google.appengine.api.datastore.*;
// [START example]
@SuppressWarnings("serial")
public class HelloServlet extends HttpServlet {
@Override
public void doGet(HttpServletRequest req, HttpServletResponse resp) throws IOException {
PrintWriter out = resp.getWriter();
DatastoreService datastore = DatastoreServiceFactory.getDatastoreService();
Entity employee = new Entity("Employee");
employee.setProperty("firstName", "Antonio");
employee.setProperty("lastName", "Salieri");
Date hireDate = new Date();
employee.setProperty("hireDate", hireDate);
employee.setProperty("attendedHrTraining", true);
datastore.put(employee);
out.println("Hello, world");
}
}
// [END example]
これを mvn appengine:update でデプロイしてGoogleのサーバーで見ると動いているのですが、
mvn appengine:devserver でローカルでテストしようとすると下記のエラーがでます。
HTTP ERROR 500

どうすればローカルでも動作するようにできるでしょうか？
