Windows无法找到'C：\ E812 \ system \ oc4j \ startOC4J.bat'

Question

我正在使用JD Edwards EnterpriseOne 8.12 DEMO 当我单击JDEdwards Solution Explorer»工具»EnterpriseOne菜单时，出现以下错误

ERROR 1

Windows cannot find 'C:\E812\system\oc4j\startOC4J.bat'. Make sure you typed the name correctly, and then try again. To search for a file, click the Start button, and then click Search.

当我按下“确定”时，会出现一个标题为“正在启动Web服务器”的小型弹出窗口和一个进度条。在这个窗口之后，我得到了以下错误

ERROR 2
Could not start Web Server

ERROR 3
Failed to Launch E1 Menu on HTML Engine

如何解决问题？
