This error indicates that the C++ compiler thinks that jboolean and jbyte are the same types. Could it be that you're picking up gcj header files instead of the correct JDK ones as this tends to happen on redhat ? What is the first jni.h file in your header include path (including the implicit locations like /usr/include, etc...) ?
Andi..
