【问题标题】：Error in deploying a Ear file in WildFly 9在 WildFly 9 中部署 Ear 文件时出错
【发布时间】：2015-12-28 05:43:15
【问题描述】：

我有一个 EAR 应用程序，其中包含一个 EJB 应用程序、WebApp 和一个客户端 jar。

我在 WildFly 中创建了数据源，名称如下：

java:jboss/datasources/NersTspDS
java:jboss/datasources/NersDS
java:jboss/datasources/NersMgtDS

在部署应用程序时出现以下错误

Wildfly 日志中的错误：

【问题讨论】：

错误信息应该比这更多。在您的日志中查看此消息上方。
此错误表明您正在从您的 persistence.xml 文件中引用一个名为 NersMgtDS 的数据源，但尚未在standalone.xml 中定义它

标签： hibernate ejb wildfly ejb-3.2

【解决方案1】：

错误是因为我在应用程序的 persistence.xml 中使用了多个数据源，我需要在 WildFly 的 Standalone.sh 文件中启用该属性以允许多个数据源。添加此属性后，错误消失了。
