エンティティが別々になっていない場合は、次の異なるパッケージに存在し、あなたが以下のようにpackagesToScanプロパティを設定することにより、各persitenceユニットに関連付けられているエンティティ制御することができますエンティティと仮定すると
両方の永続ユニットで trueを追加してみてください。 –

OK、もう一度やり直してください。結果は新しいエラーです： 原因：org.hibernate.hql.internal.ast.QuerySyntaxException：TableParameterがマップされていません。本当に奇妙なエラーですが、このテーブルは最初の永続性ユニットに属します –
persistence.xmlにクラスがリストされていないので、 trueの場合はどうでしょうか？おそらくすべてを除外しますか？私が下に投稿したこの答えはうまくいくでしょう。 –
