我们正在从JDeveloper版本 10.1.3.1 迁移到 10.1.3.4 。我们将JDeveloper 10.1.3.4解压缩到 C：/ jdeveloper 。但是，在启动时，我们遇到以下错误：

之前有人遇到过同样的错误吗？

Answer 1

我通过在JDeveloper安装中添加一个lib目录来解决问题。例如： C：/ JDeveloper10133 /的 LIB 的

然后我在lib目录中添加了缺少的jar文件（xmlparserv2.jar），例如：

C：/JDeveloper101.3.3/lib/的 xmlparserv2.jar 的

runnnig JDeveloper 10.1.3.4时出错：java.lang.NoClassDefFoundError
