Re: calling external classes method from kawa

[Damien MATTEI <Damien.Mattei@unice.fr>]

thanks you,

finally we got it:
[mattei@moita Jkawa]$ java -cp /usr/local/share/java/kawa-2.1.jar:/home/mattei/NetBeansProjects/Sidonie/build/web/WEB-INF/classes kawa.repl -C ResultatGeneralFKawa.scm
(compiling ResultatGeneralFKawa.scm to eu.oca.kawafunct.ResultatGeneralFKawa)

no more warnings at compilation (will check the runtime later)

for info -J option seems unrecognized on my kawa version (compiled from sources) but that's not a problem as it compiles the other way:

[mattei@moita Jkawa]$ kawa -J-cp -J/home/mattei/NetBeansProjects/Sidonie/build/web/WEB-INF/classes -C ResultatGeneralFKawa.scm
Unrecognized option: -J-cp
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
