The only valid values are (AFAIK) JNI_VERSION_1_4, JNI_VERSION_1_2 and
JNI_VERSION_1_1, they are listed in jni.h.

The paths you mention in the example above don't agree with what
you've posted elsewhere, where you mentioned
/usr/lib/jvm/java-1.4.2-sun-1.4.2_05.

It seems you have several java versions installed. You need to make
sure you compile and link against the correct (and same) one.
