hi again,
I think I installed Java 3d correctly... I can compile code, but the code won't run.

this is the error I am getting:

# A fatal error has been detected by the Java Runtime Environment:
# EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x0949c964, pid=3832, tid=3604
# JRE version: 6.0_16-b01
# Java VM: Java HotSpot(TM) Client VM (14.2-b01 mixed mode, sharing windows-x86 )
# Problematic frame:
# C [j3dcore-d3d.dll+0x5c964]
# An error report file with more information is saved as:
# D:\everything\javatesting\GUIchapter\hs_err_pid3832.log
# If you would like to submit a bug report, please visit:
# http://java.sun.com/webapps/bugreport/crash.jsp
# The crash happened outside the Java Virtual Machine in native code.
# See problematic frame for where to report the bug.

anyone knows what's going on? any solution?

That's a JVM crash message, not an exception. Check the hs_err log file indicated and search the net for the specific crash info reported there.

Alright, I managed to solve my issue... at least to some extent.

Java 3d API 1.5 won't work, but 1.4 is working. I also happened not to have graphics drivers installed as necessary. these two solved my issue (for anyone that might ever read this).
