Openshift在JBoss AS7上部署失败，MYSQL依赖性错误

Question

这是我之前构建的应用程序，我正在尝试配置在Openshift上进行部署。 它在我的本地设置中在独立的Jboss AS7实例中运行良好。 它构建为3个模块：.war，ejb .jar和包含这两个模块的.ear - 我认为非常标准。

有问题的错误（来自'rhc tail'）：

我认为我的配置有问题，但整晚都在寻找答案，但无济于事。 以下是一些潜在的麻烦制造者：

也许我的openshift配置文件完全错误，我很难找到任何类型的文档或指导如何执行此操作。 无论如何，如果你认为其他文件可能是其中的根源，请告诉我，我会把它们拉起来。 我对调试策略的建议持开放态度。 谢谢！

Answer 1

你做了一个小错字。

在standalone.xml中，MySQL数据源JNDI名称是jboss / datasources / MysqlDS

在persistence.xml中，您连接到名为jboss / datasources / MySqlDS的JNDI数据源

那不是相同的数据源。 使名称相同。

Answer 2

我的应用程序在openshift中运行，因为没有很多可用于openshift的文档，有两种部署，一种可以通过jenkins构建和部署，或者进行热部署（部署本地生成的war，ear和deploy）

有关不同的部署选项，请参阅openshift文档

https://www.openshift.com/developers/deploying-and-building-applications

因为我不清楚你的异常，看起来像配置问题，我觉得下面的教程将在这方面帮助你，因为我的应用程序使用jboss作为7与mysql而不是持久层，我通过这个博客，这是有帮助的

http://jaitechwriteups.blogspot.com.br/2011/08/deploy-java-ee-application-on-openshift.html

上面的博客解释了热部署，如果你正在进行热部署，请确保删除src，如openshift文档中所述

从您克隆到计算机的应用程序中删除src目录和pom.xml文件
