无法使用已安装的Java 3D

问题描述

我正在尝试在命令提示符和netbeans中使用Java 3d.我有一个win8 64位计算机.我安装了j3d-1_5_2-windows-amd64.exe.并将其安装在名为Java3D的文件夹中的java文件夹内.然后我添加了一个环境变量作为CLASSPATH，其值是C:\ Program Files \ Java \ Java3D \ 1.5.2 \ lib \ ext \ j3dcore.jar; C:\ Program Files \ Java \ Java \ Java3D \ 1.5.2 \ lib \ ext \ j3dutils.jar; C:\ Program Files \ Java \ Java3D \ 1.5.2 \ lib \ ext \ vecmath.jar.当我尝试使用命令java -cp从命令提示符运行它时，我的文件被正确编译. Hello3d，它给出了javax/media/j3d/Node的calss not found错误.当我尝试从netbeans导入3d库时，在导入com.sun之后在j3d上给出了一个错误.以下是我从命令提示符下编译的类.请告诉我我在做什么错.提前谢谢

推荐答案

您使用的Java3D版本(1.5.2)已过时，此版本已停止使用了几年.请卸载它并安装最新版本(1.6.0).按照我的说明此处.

You use an obsolete version (1.5.2) of Java3D, this version is no longer maintained since a few years. Please uninstall it and install the latest version (1.6.0). Follow my instructions here.
