SYMPTOMS

When you run a Java application that requires Java Native Interface (JNI) the following error might occur:

java.lang.UnsatisfiedLinkError:AClassWithNativeMethods.theNativeMethod Possible causes: If you are trying to use J/Direct (@dll.import), check your compiler version (for JVC, requires 4336 or greater.) If you are trying to use RNI, there are new requirements: see documentation. Probably wrong version of Java compiler.

CAUSE

When you run a JNI application using the Java Virtual Machine in the SDK for Java 2.x, you must use build 2435 or greater of the Java Virtual Machine. When you run a JNI application using the Java Virtual Machine in the SDK for Java 3.x, you must use build 3158 or greater of the Java Virtual Machine.
