Question

在使用以下指南(deploy war file using git)创建tomcat 7（JBoss EWS 2.0）应用程序后，我将war文件部署到openshift 但在部署我的应用程序后，它只显示一个空白页面。这是我使用 rhc tail 命令获得的日志。

我部署的war文件的名称是 ROOT.war ，使用git push并且它已成功部署。我正在使用mysql数据库和phpmyadmin盒式磁带。我只是想弄清楚为什么当我尝试访问我的应用程序的URL时它向我显示一个空白页面。

提前感谢。

您提供的日志根本没有帮助，因为它没有填满，我甚至无法看到抛出的异常。

这是关于在OpenShift上部署grails应用程序的最佳文章，它将为您提供很多帮助： Grails on Openshift

如果您使用ftp查看服务器上发生了什么，那么故障排除会更有效率 Using FileZilla and SFTP on Windows with OpenShift

我已经通过@Taras Kohut的帮助解决了这个问题。我将以下行添加到BuildConfig.groovy文件中。

 grails.project.war.exploded.dir = "/yourLocalPathToClonedOpenshiftFile/webapps/ROOT"
 grails.war.exploded=true

以上行将在webapps文件夹中的openshift应用程序中生成爆炸的war文件接下来，我再次在webapps目录中添加了 ROOT.war.deploy 文件。这是一个文件，它指示jboss在推送之后它必须占用ROOT文件夹并将其部署在Tomcat上（由JBoss模拟））好像它是一个战争档案。之后，我提交并推送了我的更改，应用程序已成功部署，一切正常。
