[gl4java-usergroup] Windows98-Netscape-Gl4java installation problem

[Ricardo O. <ro...@gl...>]

I use sun jdk and Netscape 7.1 in Windows 98.

I have dowload the gl4java installer, and install it correctly.

When I try to execute a gl4java demo, it says
Execption in thread "main" java.lang.NoClassDefFoundError:
gl4java/awt/GLCanvas

But if I use microsoft jvm and Internet Explorer all it's ok.

If I use Internet Explorer and sun jvm I get the same exception: Execption
in thread "main" java.lang.NoClassDefFoundError: gl4java/awt/GLCanvas


Anyone know because I can't use Netscape and sun jvm to execute gl4java in
Windows 98???

In Windows 2000 and Windows XP all works ok, I can use sun jvm and Netscape.

I use sun jdk 1.4.1_01.


I can't use the online installation for Netscape, it gives me an error.
