I have implemented jdk1.2 and java3d on my office NT machine successfully. Checked the examples and written some of my own Problem; I have tried repeatedly to do the same on my home Windows 95 machine without success. Copied downloaded files to Zip 100Mb drive and copied to hard drive before implementing. Loaded JDK1.2.1 with applet demos which run successfully. Loaded latest Java3d successfully. No luck on running any examples from demos\Java3d. Class is file is found but, " Exception in "thread java.lang.Unsarisfied Link Error c:jdk1.2.1\jre\bin\j3d.dll One of the library files needed to run this appliucation cannot be found at.. ." followed by a list of valid trials to no avail. I have no classpath set, but use run form the class directory ( as done in Java2d examples). I have tried both applets and as application with same result. The PATH includes jdk1.2.1/bin and jdk1.2.1/jre/bin/ The jar files appear to be complete. Only 16Mb of RAM abd standard output driver. I have checked and opengl is present in my Windows directory. I am now clutching at straws.
