To Java 3D:
I am having a problem with Java 3d after downloading and installing the
jdk1.2.2 standard edition of the Java Development Kit. In earlier versions
of the jdk the classpath was lib/ext for the j3dcore.jar, j3dutils.jar,
vecmath.jar files and included a bug with Windows machine that placed the
jar's in the lib folder. This machine is Windows98, Intel Pentium II. The
newer version of the jdk does not have a lib/ext folder but instead places
everything the lib folder. This will now run my Java3d unless I specify the
classpath on the command line as C:\jdk1.2.2\bin\java -cp
C:\jdk1.2.2\lib\j3dcore.jar;C:\jdk1.2.2\lib\j3dutils.jar;C:\jdk1.2.2\lib\vec
math.jar <class filename>. This is fine with me as I usually run classpath
from the command line with this system but when I attempt to run
appletviewer I find there is no way to include a classpath on the command
line. The Java plug-in is installed and all the Java3D jars are in the lib
folder but this still brings up a error SceneGraphObject not found. In
earlier versions of the jdk the Java plug-in would run Java3D as long as the
jars where in the lib folder. I don't now or in the past use a classpath in
the autoexec.bat because this is not reliable to run the java programs. I
use the command line. The question remains is there a bug in Windows as in
earlier versions of the jdk that required the movement of jars within the
jdk that I don't know of. Or is it specifically required that I enter a
classpath in the autoexec.bat. I am reluctant to use the autoexec.bat as
this rarely runs properly on my system and requires constant updates. So I
would run Java3D with the command line easily but I don't know how to run an
appletviewer and specify a classpath. Thanks for your attention.
