我在Wildfly 8.1中部署了多個戰爭和耳朵。最近，我從遷移到休眠JPA一些代碼在罐子裏的這是一個耳朵和一個war.So之間共享的一個，這是怎麼一回事呢非引用persistenceunit init拋出DuplicateServiceException：__FIRST_PHASE__已被註冊？
yy.ear
-> persistence.xml(ds2,ds3,ds4)
-> myjpa.jar
->persistence.xml(ds1)
xx.war
-> myjpa.jar
->persistence.xml(ds1)
現在，yy.ear也有它的persistence.xml（帶引用ds2，ds3 & ds4），myjpa.jar也是如此（僅引用ds1）。但是在部署期間看到的錯誤是說xx.war正在嘗試重新初始化ds4。我檢查了所有的源代碼，但在xx.war或myjpa.jar中沒有提到ds4。 那麼如何解決這個部署錯誤呢？下面的服務器日誌..
也要添加yy.ear正確部署，但xx.war沒有。
