I have recently installed opl development studio 4,2.
I have problems getting the java interface to work.
When running when the examples by running run.bat, I get the following error message:

C:\ILOG\OPL42\examples\java\warehouse>run
run
Buildfile: build.xml

compile:

run:

I can't find anything on this JVMARGS on the internet, does anyone know why I get this error.

I am running java version 1.6.0_13, so it should be new enough.

Hope someone has an idea how to around this problem.

HI,

yes the JVM is new, but :

>I have recently installed opl development studio 4,2.

this one is quite old.
Even if normally this should not be a problem, you might want also to sue a more recent OPL version.
