工作学习 / 专业技术讨论 / Ugent! Java JNI , 各位JAVA 高手, pls help!I have one problem urgently! I need to have a 32 bit windows dll with a C style interface created. how can I create a C wrapper around the .java file using the Java Native Interface (JNI)? Is it free to use JNI?
I am not familiar with Java, I would be appreciated if anyone can help. This is very urgent.
Thanks in advance

用C编译器生成dll,用JNI调用就得了，免费的，具体操作网上自己查吧，多的是。

If you already have the java file, run javah against the compiled class. This creates a C header file xx.h , include this header xx.h in your c program ...google it and you will find lots of example: http://java.sun.com/j2se/1.4.2/docs/guide/jni/index.html
