AWS SDK for Java を使って S3 に接続するごく簡単なサンプル

シンプルなサンプルなので、Amazon Web Service (AWS) に興味のある人なら説明の必要もないでしょうね。

S3 に接続して Bucket一覧を表示するだけのサンプルです。

詳しい説明はこちら　http://bonk.red/articles/AWS/aws_sdk_java.html

S3Conn.java

/*
 *  Connect to S3 and list bucket names.
 *    Environ variables "AWS_ACCESS_KEY_ID", "AWS_SECRET_ACCESS_KEY", "AWS_REGION" must be defined.
 *       Visit http://bonk.red for details
