Question

我使用Jdeveloper Studio 11.1.1.4.0，我在其上使用ADF组件，但是在我启动Jdeveloper的最后几天，出现了此错误

Uncaught exception
java.lang.NoClassDefFoundError: Could not initialize class oracle.dbtools.raptor.config.DBConfig

我也找不到数据库导航器，当我使用与数据库相关的任何内容时也会出现此错误，我尝试卸载Jdeveloper并删除中间件文件夹并重新安装所有内容以获取默认但仍然相同的故事

我真的需要一个解决方案，因为我已经落后于我的毕业设计。

感谢。

检查你的类路径，这里一定有问题，验证JDevelloper文件夹在

中

Jdeveloper错误“java.lang.NoClassDefFoundError：无法在启动时初始化类oracle.dbtools.raptor.config.DBConfig”
