我正在我的Wildfly 8.1中部署多个战争和耳朵。最近，我将一些代码从休眠迁移到其中一个罐子中的jpa，该罐子在耳朵和战争之间共享。所以事情是这样的
yy.ear
-> persistence.xml(ds2,ds3,ds4)
-> myjpa.jar
->persistence.xml(ds1)
xx.war
-> myjpa.jar
->persistence.xml(ds1)
现在，yy.ear也有它的持久性.xml（引用ds2，ds3和ds4），myjpa.jar也是如此（仅引用ds1）。但是在部署过程中看到的错误是说xx.war正在尝试重新初始化ds4。我已经检查了所有源代码，但在xx.war或myjpa.jar中没有看到对ds4的引用。那么如何解决此部署错误呢？服务器日志如下..
另外要添加yy.ear可以正确部署，但xx.war没有。

问题原来是具有过时架构的表。删除这些内容后，部署完成，没有任何错误。
