我采取了计算机图形课程，我的大学。我无法使用Java，因为我没有它正确安装3D图形。我从Oracle下载了Java 3D API。没有包含安装程序。就在原始文件j3dcore.jar，j3dutils.jar和vecmath.jar以及一些自述文件。一个读我的文件确实包含有用于安装说明的链接。它说我一定要解压缩的Java 3D 1.5.1进入JRE你的JDK的目录。哪里是我的JDK？我发现我的Java文件夹系统>库>的Java>扩展和移动文件那里，因为我看了一些其他的东西在网上。我的编码时，仍然可以在Eclipse中此错误消息：访问限制：方法[无论]从类型[无论]是无法访问的，由于限制所需的库/System/Library/Java/Extensions/j3dutils.jar。但我有这个文件正是它说，它应该是。

I am taking a computer graphics course at my university. I am unable to create 3D graphics using Java since I do not have it properly installed. I downloaded the Java 3D API from Oracle. There is no installer included. Just the raw files j3dcore.jar, j3dutils.jar, and vecmath.jar as well as a few read me files. One of the read me files does contain a link that has instructions for the install. It says I must "Unzip Java 3D 1.5.1 into the "jre" directory of your JDK." Where is my JDK? I found my Java folder System > Library> Java > Extension and moved the files there because I read some other things online. I still get this error message in Eclipse when coding: "Access restriction: the method [whatever] from the type [whatever] is not accessible due to restriction on required library /System/Library/Java/Extensions/j3dutils.jar." But I have this file exactly where it says it should be.
