Googleカレンダーで遊ぶ

会社で使っているスケジュールボードをリモートからも見たくてGoogleカレンダーと同期できないか思案してのPG。

久々なので、Eclipse3.6の環境をきれいにクリーンインストールしてからスタート。

まずは、GDateのサンプルをダウンロード。Eclipseで新規Javaプロジェクトを構築して解凍した一式を配置。

ただ、J2EEライブラリへのパスが無かったので、 GlassFishのライブラリを追加。最初は該当JARを探すも、

１．windows＞設定＞サーバ＞ランタイム環境より、追加でJ2EEコンテナを追加

２．プロジェクトのビルドパスに ライブラリの追加＞サーバ・ランタイムを行う

で適当なライブラリを追加してくれるので、コンパイルは通るようになる。

今回動かしたいカレンダーのサンプルのREADME.txtを見ると

The application can be built and run using the provided Ant build file found at

gdata/java/build.xml.  The sample can be run in the following manner:

1.  Edit gdata/java/build.properties to enter your Google Account username and
    password, as well as the feed URI on which you want to test the sample.

2.  Invoke the sample using the following commandline:

    ant -f gdata/java/build.xml sample.calendar.run

とあるので、gdate直下（今回はプロジェクト直下）にbuild-samplesスクリプトは以下の、build.propertiesをコピーして、build.samples.xmlのsample.calendar.runを実効

すると

と出る。解凍したパッケージを適切にプロジェクトに配置できていなかったので修正して実施。

（SRCフォルダと、build.xmlの関係が不適切だった）

Buildfile: C:\Users\jun\workspace\GoogleCalendarTest\gdate\build-samples.xml

今度は、version.propertiesを適当なフォルダに置けていなかった。

配置を修正してひとまず、サンプルは動いた。でも、内部エラーも出ている。今日はひとまずここまで。

PS:Eclipse3.6でAnt使ったが、Taskへのリンク機能が超便利。また、外部ファイルをproperty file属性で読み込んでいるのも知らないテクなので関心。Googleのサンプルでは、JARファイルのバージョンをversion.xmlとして外出しにして、指定したバージョンのファイルを取得する作りとなっていた。Eclipseプロジェクトのビルドパスが動的に指定出来れば良い手として使えそう。
