在带有PostgreSQL的OpenShift JBoss上部署WAR失败-缺少依赖项错误

我是OpenShift新手，并使用JBoss AS7和PostgreSQL 9.2 gears创建了我的第一个应用程序。我成功创建了DB，并尝试部署现有WAR，遵循我在这两页上找到的指导：

当我进行git推送时，我得到以下信息：

每个OpenShift JBoss应用程序都有三个数据源（H2、MySQL和PostgreSQL）在standalone.xml JBoss配置文件中配置。在persistence.xml中，确保您使用的是

java:JBoss/datasources/PostgreSQLDS

JNDI datasource，否则会出现异常。您可以在.openshift/config目录中找到standalone.xml。

我找到的解决方案是在我的web-INF中创建一个专有的JBoss-web.xml文件我的战争目录

在战争中，WEB-INF/jboss-WEB.xml包含：

<?xml version="1.0" encoding="UTF-8"?>
<jboss-web>
  <resource-ref>

使用这些文件（以及standalone.xml和jboss web.xml中匹配的JNDI名称），WAR成功部署。

谢谢Shekhar。我之前在standalone.xml中看到了3个数据源，并完全删除了H2和MySQL的数据源。我没有persistence.xml文件，因为我的WAR只包含一个带有servlet的web应用程序，没有EJB。缺少persistence.xml文件可能是我的一部分吗问题？您如何配置数据源？我在上面添加了详细信息（standalone.xml和context.xml）。还有什么其他详细信息会有帮助？您是否尝试在本地计算机上运行此应用程序？我还没有尝试在本地运行，但现在我已经尝试了。我在standalone/d部署中部署了WAR
