私は動的Webプロジェクトを作成し、Eclipseの火星にJPAファセットを追加しました。 私のビルド・パスには、jdk8、EclipseLink 2.6、JPA 2.1、Tomcat 8、Oracle Thin Driver（ojdbc14.jar）があります。eclipse linkとoracle dbでテーブルを生成できません - IllegalBlockSizeException
同じプロジェクトが一部のマシンでは動作しますが、他のマシンでは動作しないため、奇妙なことがあります。
私は単なるjpaプロジェクトのエンティティからテーブルを生成したいので、tomcatは必須ではないと思います。
私は2つのJPAエンティティを作成しましたし、私は私のOracleデータベース（成功のPing）を指すようにpersistence.xmlを設定しました：
