我正在使用Apex 4.2.4.00.08 / ORDS 3.0.7 / JRE 1.8.0.102 / Oracle XE 11g。我的服务器是Windows 10，内存为16 Gb。我使用JRE 1.8.0启动ORDS。
我登录现有的Apex应用程序，可以访问大多数屏幕。最近我无法显示一年左右未修改过的页面。当我尝试访问该页面时，URL显示为：http://localhost:9090/ords/wwv_flow.accept，错误为：500 - 内部服务器错误。
该页面只是一个交互式报告，其中一个非常简单的查询从一个表中选择字段。基于其他一些帖子，我通过编辑.... ords \ ords \ defaults.xml打开了一些Debug信息。我添加了一行：
<entry key="debug.printDebugToScreen">true</entry>
并重新启动ORDS的Java任务。现在，当我访问交互式报告页面时，我得到了调试信息。但是，我仍然无法弄清楚问题是什么。我查看了基于Debug的错误ORA-01044，但大多数讨论已有很多年了。我从另一台服务器导入了应用程序，以检查应用程序是否以某种方式损坏。我得到了相同的结果。您能否根据以下调试确定我为什么会收到500 - 内部服务器错误？ 调试痕迹
