Re: [gl4java-usergroup] Packing GL4Java with a program

[Montana, P. M <pat...@lm...>]

Gary, 

(BTW, I am assuming a Windows OS for this discussion.) 


We distribute our program with GL4Java.  However, we also provide the SDK,
Java3D, JAI, and some various comm packages. Our approach was to install the
SDK on our development machines, then we installed Java3D and JAI within
that SDK (using the standard installers). Next, we copied the relevant
GL4Java jar files to: 
j2sdk/jre/lib/ext 


This way the JVM can find the jar files automatically when it runs (any
program, not just ours). Then we copy the GL4Java .dll's into the bin
directory for our application (where we have the batch file that launches
our application). You could also copy the .dll's to the j2sdk/bin directory.
The point is, those dll's have to be in the directory that you run from, or
they must be in a directory that is set in your PATH environment variable.
If you want to copy stuff into people's System32 directory, then it is
automatically in their PATH variable. 


And don't forget to include the appropriate license files, readme files, and
other documentation required by the software providers. 


Then we include our entire SDK with our application using InstallShield. The
installation is a simple "Next, Next, Next" operation for the user. Then
they have an icon on their desktop (and an entry in the Start menu) to
launch our program with no troubles. 


Hope that helps.

Assuming you can roughly predict that someone is using a given setup is it 
possible to pack GL4Java with a program? Looking at it you need the .dll (or

.so) that matches the java version (1.4 in this case) and the GL4Java jar
files. 
From that is it possible just to provide the .dll and jars in a zip with the

program and someone launching your program will hopefully have it running
*if* 
the enviroment and class path reference "." and the jar files are in the
class 
path (for example if you use another jar with extensions). 


Many thanks, 


Gary
