hi,
i want to change my JVM properties("user.dir", "os.name" etc...) using JNI.
So the setProperty() method have 2 parameters that's why i have tried to 
do this :

sys = (*env)->FindClass (env, "java/lang/System");

meth = (*env)->GetStaticMethodID (env, sys, "setProperty", 
"(Ljava/lang/String;)Ljava/lang/String;","(Ljava/lang/String;)Ljava/lang/String;");

(*env)->CallStaticObjectMethod(env, sys, meth, (*env)->NewStringUTF 
(env, &key),(*env)->NewStringUTF (env, &newVal));

I don't understand why it doesn't work.

Can anyone help me?
Thanks by advance
