これについては@bkailに同意します。
WAS 7 での実行中に同様の問題に直面していました。回答の最初のオプションに従って解決しました。クライアントは同じサーバーを使用して複数のアプリケーションをホストするため、2 番目のオプションはお勧めしません。
それに加えて、WAR プロジェクトjbpm-test-5.4.0.Final.jarとEAR -> Deployment Assembly同様に jar ファイルも削除しました。WEB-INF/libそうしないと、Websphere が jar 内のデータ ソースを検出するため、最初のオプションだけでは機能しません。

<jta-data-source>java:comp/...</jta-data-source>コンテナ管理の Hibernate JPA ではうまく機能しません。WebSphere Application Server は、アプリケーションで他のほとんどすべてを実行する前に、createContainerEntityManagerFactory を呼び出す必要があります。これは、この呼び出しによって、エンティティーのバイトコードを変更する必要がある ClassFileTransformer が登録される可能性があるためです。

オプションは次のとおりです。

  1. <jta-data-source>java:comp/...</jta-data-source>サーバーの名前空間 (例: ) から JNDI 名の使用を削除して使用します<jta-data-source>jdbc/myds</jta-data-source>。

  2. APAR PM26361の説明に従って、アプリケーションのコンテナー管理 JPA を無効にします。(この APAR は、アプリケーションの開始時に createContainerEntityManagerFactory への呼び出しによって引き起こされるパフォーマンスの問題について説明していますが、この問題を回避するためにプロパティを使用することもできます。) もちろん、コンテナー管理の JPA を無効にすると、@PersistenceUnit/@PersistenceContext注釈または<persistence-unit-ref>/を使用できなくなります<persistence-context-ref>。

この投稿が言ったように、データソースの名前に関連しているようです..最初にそれを試して、2番目のエラーが発生するかどうかを確認してください: https://www.ibm.com/developerworks/community/forums/html/topic?id=77777777- 0000-0000-0000-000014210826
