JNI入门小例子

http://www.ibm.com/developerworks/cn/education/java/j-jni/index.html

参照developworks上的讲解，一步步往下做

cl -Ic:\jdk\include -Ic:\jdk\include\win32 -LD Sample1.c -FeSample1.dll

这行指令，得放到

visual studio 2008 command prompt底下执行

cl -Ic:\IBM_JDK_60\include -Ic:\IBM_JDK_60\include\win32 -LD "C:\Documents and Settings\yiwen\My Documents\Visual Studio 2008\Projects\testjni\testjni\Sample1.cpp" -FeSample1.dll

文件名有空格的得用“   ”括起来

将Sample1.dll拷贝到Sample1.class 文件夹下，用CMD进到Sample1.class 文件夹下

运行java Sample就能出结果了
