私は2日を費やしましたが、まだ問題を解決できません。
私の問題は、JPA と Hibernate を使用する war ファイルがあることです。Windows JBOSS AS 7.1.1 にデプロイすると、正常に動作します。ただし、Centos 5.8 JBOSS AS 7.1.1 にデプロイすると、例外がスローされます。根本的な原因は非常に一般的です: 原因: javax.persistence.PersistenceException: No Persistence provider for EntityManager named XX
2 つの OS で動作が異なる理由がわかりません。両方のマシンで JDK7 update 21 を使用しています。
開発マシン: Windows 7(64bit)、Eclipse IDE、JDK7_21 展開マシン: Centos 5.8(64bit)、
使ってみました
ClassLoader loader = Thread.currentThread().getContextClassLoader();
Enumeration<URL> resources1 = loader.getResources("/META-INF/persistence.xml");
URL seurl = resources1.nextElement();
ただし、これは Windows 7 でのみ機能し、Centos では persistence.xml を取得せず、.nextElement()を呼び出すと NOSuchElement Exception がスローされます。META-INF フォルダーをリソースとして配置し、展開すると、この場所 xx.war/WEB-INF/classes/META-INF/persistence.xml に配置されます。
誰かが何が問題なのかを見つけるのを手伝ってくれますか? どうもありがとう。
スローされた例外も投稿したいと思います：
