Re: [gl4java-usergroup] cannot run demos

[Jack S. <ja...@ji...>]

This error message/scenario sounds familiar.  I was trying to install  
gl4java on a WinXP/JRE1.3.1/IE6 test machine, and was getting the same  
exception.  (Install went fine on Win2K and MacOSX)  Here's the  
sequence of events and errors I went through as I tried to install  
gl4java on WinXP:

1. Tried to install via the "Automatic Installation (download the  
Installer)" link. When I tried to run the "install.bat", either via  
double-clicking, or via the command prompt it wouldn't run.  Via the  
command prompt, I would see this error:

C:\Downloads\GL4JavaInstall\gl4java- 
INSTALLER\GL4Java\Installer>install.bat
Files\JavaSoft\JRE\1.3.1_04\lib\ext\QTJava.zip"" was unexpected at this  
time.

2.  Next I turned off the Java2 plug-in modified the java.policy file,  
and tried the web installer.  In the installer, the "native libs"  
directory path was not set, so I had to navigate to locate it.  It  
finished the installation, and said everything was installed properly.   
I tested it on a demo applet and received the  
Exception:java.lang.NoClassDefFoundError: gl4java/awt/GLAnimCanvas1  
error.  I did a search for the gl4java.jar, png.jar, etc. and for  
whatever reason, they weren't installed.

3. After several retry's, I decided to do the manual binaries  
install.....this works fine.

Thought I should pass it on....
