Talk:OpenGL:Tutorials:Java:JOGL:Introduction
<Note from a reader: You may want to use Frame instead of JFrame. JOGL is much slower in lightweight swing applications because GLCanvas is a heavyweight object.>
Also please note that setting fullscreen window is problematic with jogl on version "1.4.2_08-b03". It probably works without the fullscreen part.
Hm, I never considered that. Java 5 has been out for a while though, maybe it is you who should upgrade. :P --Dial-Up 20:54, 14 Jun 2005 (EDT)

Then..... ?
Make sure that the files are in the proper directories. Remember that the "natives" JAR file actually needs to be extracted. --Dial-Up 22:25, 28 Jun 2005 (EDT)
JOGL import problems
This looks like a great tutorial--unforturnately I haven't been able to run it. I've been reading through this tutorial after reading over several others and I've found that some tutorials refer to javax.media.opengl.*; as the proper JOGL import path (such as http://thepanda.org/article/joglness half way down the page) while this tutorial and others refer to net.java.games.jogl.*;. Based on the version I got from the website I can import the javax mentioned above and not the net extension. Under an earlier installation of OpenGL (and yet another tutorial), the opposite was true. In both cases I followed the process of extracting the native JOGL jar to the bin folder while the main jar was placed in the lib/ext folder.
- I figured this issue out: for JOGL version 1.x, the proper import path is
import net.java.games.jogl.*; Version 2.0 requires an import path of javax.media.opengl.*; Unfortunately this doesn't seem to be documented anywhere.
getGLU()
getGLU() is no longer a method of GLAutoDrawable; instead, you just create a new GLU() and it seems to automatically detect what GL to use (if someone could explain that to me, that'd be great)
JOGL in java
Hi this is kasiram i am new in jogl,i use this version jogl-1.1.1-windows-i586,and i am running bellow program this error will come G:\kasi\FUNCTIONS\OpenGL>java HelloWorld Exception in thread "main" java.lang.ExceptionInInitializerError
at HelloWorld.main(HelloWorld.java:18)
Caused by: javax.media.opengl.GLException: No profile available: [GL2, GL2ES2, G L2ES1, GLES2, GLES1, GL2GL3, GL3]
at javax.media.opengl.GLProfile.<clinit>(GLProfile.java:750)
... 1 more
and i add jar files in gluegen-rt.jar,jogl.all.jar,jogl.jar,nativewindow.all.jar,newt.all.jar files in this place and i add class path also
E:\Program Files\Java\jdk1.5.0_06\jre\lib\ext place
and i add ddl files in jogl.ddl,jogl_awt.ddl,jogl_cg.ddl,natinewindow_awt.ddl,nativewindoe_jvm.ddl in the this
E:\Program Files\Java\jdk1.5.0_06\jre\bin place add path also
