Google App Engine 1.2.6の起動時エラー

EclipseのApp Engine Pluginを1.2.6にアップしたら

既存プロジェクトの起動がエラーになってしまった。こんな。。

java.lang.RuntimeException: Unable to locate the App Engine agent. Please use dev_appserver, KickStart,  or set the jvm flag: "-javaagent:<sdk_root>/lib/agent/appengine-agent.jar"

....

Caused by: java.lang.ClassNotFoundException: com.google.appengine.tools.development.agent.AppEngineDevAgent

....

エラー内容に書いてあるとおりに

vmオプションに"-javaagent:<sdk_root>/lib/agent/appengine-agent.jar"を付けってやると動くようになった。

これはプラグインのバグなのか？(　´д`)

Google Calendar APIを使ってみた。

RESTfulでJSON形式を利用してみた。

これはAndroidで使える。

alt=jsonを付けないとXML形式（デフォールト）になる。

gsessionidを取得するのは最初一回やる必要がある。登録、変更処理で必要。

Chromeにテーマが適用

気づくのが遅かったけど、いつの間にかChromeにテーマが適用された。

http://googlejapan.blogspot.com/2009/08/google-chrome-beta.html

不思議な感じがする。(´∀｀)

Google Chrome OSはやっぱり無料だな

http://jp.techcrunch.com/archives/20090708chrome-partners-acer-adobe-asus-freescale-hewlett-packard-lenovo-qualcomm-texas-instruments/

当然だと思ってるけど、Google Chrome OSは無料でオープンソースらしいだな。

今後、Googleアラートに登録して監視しよう。

Google Chrome OS 発表

おお

Google Chrome OSが　2010年出るのか。。　気になる。

http://googlejapan.blogspot.com/2009/07/google-chrome-os.html

GAE/JのJPA

GAE/JでBigTableをJPAで利用してみた。

① META-INF/persistence.xml

<?xml version="1.0" encoding="UTF-8"?>

<persistence xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://java.sun.com/xml/ns/persistence

http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd"

version="1.0">

<persistence-unit name="transactions-optional">

<provider>org.datanucleus.store.appengine.jpa.DatastorePersistenceProvider</provider>

<properties>

<property name="datanucleus.NontransactionalRead" value="true" />

<property name="datanucleus.NontransactionalWrite" value="true" />

<property name="datanucleus.ConnectionURL" value="appengine" />

</properties>

</persistence-unit>

</persistence>

② EMF

package com.babukuma.gae.test.jpa;

import javax.persistence.EntityManagerFactory;

import javax.persistence.Persistence;

public class EMF {

private static final EntityManagerFactory emfInstance = Persistence

.createEntityManagerFactory("transactions-optional");

private EMF() {

}

public static EntityManagerFactory get() {

return emfInstance;

}

}

③ エンティティ

package com.babukuma.gae.test.entity;

import java.util.Date;

import javax.persistence.Column;

import javax.persistence.Entity;

import javax.persistence.GeneratedValue;

import javax.persistence.GenerationType;

import javax.persistence.Id;

import com.google.appengine.api.users.User;

@Entity

public class SimpleBoard {

@Id

@GeneratedValue(strategy = GenerationType.IDENTITY)

@Column(nullable = false)

private Long id;

@Column

private User author;

@Column

private String content;

@Column(nullable = false)

private Date date;

public SimpleBoard(User author, String content, Date date) {

this.author = author;

this.content = content;

this.date = date;

}

public Long getId() {

return id;

}

public User getAuthor() {

return author;

}

public String getContent() {

return content;

}

public Date getDate() {

return date;

}

public void setAuthor(User author) {

this.author = author;

}

public void setContent(String content) {

this.content = content;

}

public void setDate(Date date) {

this.date = date;

}

}

④ テストコード

package com.babukuma.gae.test;

import java.io.IOException;

import java.util.Date;

import javax.persistence.EntityManager;

import javax.servlet.http.HttpServlet;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import com.babukuma.gae.test.entity.SimpleBoard;

import com.babukuma.gae.test.jpa.EMF;

import com.google.appengine.api.users.User;

import com.google.appengine.api.users.UserService;

import com.google.appengine.api.users.UserServiceFactory;

@SuppressWarnings("serial")

public class DataStoreTestServlet extends HttpServlet {

public void doGet(HttpServletRequest req, HttpServletResponse resp)

throws IOException {

UserService userService = UserServiceFactory.getUserService();

User user = userService.getCurrentUser();

String content = req.getParameter("content");

System.out.println("content=" + content);

Date date = new Date();

SimpleBoard board = new SimpleBoard(user, content, date);

EntityManager manager = EMF.get().createEntityManager();

try {

System.out.println("before insert");

manager.persist(board);

System.out.println("after insert");

} catch (Exception e) {

e.printStackTrace();

} finally {

manager.close();

}

resp.setContentType("text/plain");

resp.getWriter().println("Hello, world");

}

}

これ以外に簡単にできるんだな。。（＾（エ）＾）

Linux版Chromeが使えるようになった

Linux版Chromeが使えるようになった。

何故か今日Ubuntuのシステムアップグレードしてから疲れる気がする。

勝手にバージョンアップされたかな？

でも。。。なぜかHtmlのテキストボックス（input, textarea）では日本語が書けない。。

Linux版 Chrome

（-（エ）-）これが最初のステップだ
