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

[Antony R. <ri...@to...>]

Having had no success all day, I decided to try and use something previously
unknown to me - batch files.

Batch files are quite scary - in terms of their simplicity and power.  I
came up with the following batch code that would run my sample java class
passing various system properties using the syntax specified by Pepijn.

... and it seems to work on all my home computers!!  I'll have to wait until
tomorrow to test on works systems, but don't see there being a problem at
all.

A quick google search for "creating batch files" should provide you with an
abundance of information on how batch classes work (which was my main
problem).

I found this site to be quite good:
http://home.att.net/~gobruen/progs/dos_batch/dos_batch.html

Find below my sample batch code (setting the "java.ext.dirs" property in
this example):

@echo on

rem
rem Determine if JAVA_HOME is set and if so then use it
rem
if not "%JAVA_HOME%"=="" goto found_java

set RIBOTSIM_JAVACMD=java
goto file_locate

:found_java
set RIBOTSIM_JAVACMD=%JAVA_HOME%\bin\java

:file_locate
rem %~dp0 is name of current script under NT
set RIBOTSIM_HOME=%~dp0

rem : operator works similar to make : operator
set RIBOTSIM_HOME=%RIBOTSIM_HOME:\bin\=%

rem attempting to run the main java command, passing in system properties
"%RIBOTSIM_JAVACMD%" -cp e:\ "-Djava.ext.dirs=%RIBOTSIM_HOME%\libs" GLTest
%1 %2 %3 %4 %5 %6 %7 %8 %9

:end

What do you mean by this registry key? As far as I know gl4java does
not access the windows registry. What I meant by specifying the system
property is this:
java -Djava.library.path=<some path> YourApplication
This setup works fine for me on every machine I've tested on. The only
limitation is that you can't do this when you are running your
application as an applet or via webstart. (Both are possible but
require some more effort)
