DEMO环境已经安装好,但是进入DEMO系统时总是会弹出如下的框图,不知道是什么原因??帮助我分析分析!在此跪谢!

The reason is due to your JDE.INI setting, there are two solution for this:
1. you can find as following setting in JDE.INI
"AppServerInstalled=1", pls set the value to 0.
2. find your java sdk path in your path setting from computer property. Add the SDK directory to your path property.  if you dont want to install JDK, you can find as following path to locate the jdk which DEMO installs (e811/system/JRE/1.4/bin)

JDK安装在“x:E812systemJDK”目录下就没这问题了

Of couse, Actually, the fastest solution is go to modify the path in your startOC4J and stopOC4j  start script to your JDK path.
