dspace错误空白xmlui页面
dspace error blank xmlui page
我已经在我的 Ubuntu 16.04 计算机上从源代码安装了 dspace。我按照此处详细说明中的步骤操作：
https://wiki.duraspace.org/display/DSDOC6x/Installing+DSpace
当我尝试访问 xmlui 页面时，浏览器出现白屏，日志中出现一长串错误消息，如下所示。我已经检查过，在 src 目录中，Context.java 有方法 getCurrentMode，它被 CommunityBrowser.java 在第 150 行调用。当我转到 jspui 时，我得到了一个不错的页面，但是出现了同样的错误当我登录时，虽然它在页面上显示一条错误消息，而不是像 xmlui 一样什么都不显示。
任何人都可以提出建议吗？

还有更多茧错误...
最初，在第一天，我在安装过程中犯了几个错误。例如，我第一次在 dspace.cfg 或 local.cfg 中设置数据库密码失败。我设置了密码，然后在没有先删除所有内容的情况下再次尝试。我以为它会覆盖并更正任何错误。
所以在@Jens 的建议之后，我认为对于使用与 dspace 一样多的 jar 文件的安装来说，尝试查找冲突的 jar 文件将非常困难。所以我第二天从头开始再次尝试。我下载了一个新文件，我从文件系统中删除了我的数据库和所有 dspace 文件。我开始了，从我的错误中吸取了教训，我顺利地完成了安装步骤，最后一切正常。我现在有一个可以修改的源代码安装。
