安装 Hippo CMS : NullPointerException with essentials webapp

Question

我按照这些说明 (Hippo CMS installation instructions) 安装了 Hippo CMS 7。

我关注了:

第 1 步：运行本地 Maven 原型
第 2 步：使用 Maven 在本地编译和打包
我没有按照步骤 3 的说明进行操作，因为我在 Windows 8.1 上构建了 WAR 文件（cms.war、essentials.war 和 site.war） / Oracle JDK 8 / 本地 Maven 3.3 并在 Debian 7 上传输生成的 WAR 文件 / Oracle JDK 8 / Tomcat 8 / 无 Maven 服务器

我得到的：

http://{myserver}:{myport}/cms 运行良好
http://{myserver}:{myport}/console 运行良好
http://{myserver}:{myport}/site 运行良好
http://{myserver}:{myport}/essentials 给出 HTTP 500 错误代码（但 WAR 已正确部署和启动）

堆栈跟踪：

似乎"GET /essentials/rest/plugins" web 服务是产生异常的调用。

你有什么想法吗？

Answer 1

如 One Hippo 的设置 instructions 所述，设置应用程序仅适用于本地开发主机。

这是因为它与您的项目文件有很强的交互作用。因此，在远程服务器上使用它没有多大意义。离开开发主机后，不要费心部署必需品 WAR。（请注意 Hippo 项目分发如何不包含必需品 WAR。）
