Note that documentation for the java command says:

    When you use the -jar option, the specified JAR file is the source of all
    user classes, and other class path settings are ignored.

So you may need to use a -cp flag instead, and explicitly name kawa.repl :

java -cp /usr/local/share/java/kawa-2.1.jar:other.jar kawa.repl -C ResultatGeneralFKawa.scm

The Kawa command allows you to use a CLASSPATH enviornment variable.

The -jar option overrides the classpath.  Instead you

Huh?  A standalone -J makes no sense, since you didn' specify any options.
Instead, you can do:

   kawa -J-cp -Jmyclasses.jar

Note you have to use two -J's - one for each JVM option.

It might be easier to use a CLASSPATH environment variable.
