The well-known tradeoff of Java's portability is the inefficiency of its basic execution model, which relies on the interpretation of an virtual machine. Many solutions have been proposed to overcome this problem, such as just-in-time(JIT) and offline bytecode compilers. However, JIT compiler can not avoid the overhead of runtime. since it translate bytecode into native code at runtime. And, pure offline bytecode compiler limits the ability of dynamic class loading. In this paper, we present an approach which preserves the ability to dynamically load bytecode, and is more efficient than JIT. In contrast to existing bytecode-to-C translator using the old NMI, our translator maintain complete compatibility and portability through using the Java Native Interface(JNI) standard. We have designed and implemented an translator for converting bytecode to C code with JNI.. named MyJNItool.
