类名：mydll.java
代码：
public class mydll{
public static final String DLL_NAME1 = "ZSComm.DLL";
private static JNative jn;
public static int GSC_GetDLLVersion(String version) throws NativeException, IllegalAccessException{
int ret =0;
try {
jn = new JNative(DLL_NAME1,"GSC_GetDLLVersion");
//设置此函数的返回值
jn.setRetVal(Type.INT);
int i = 0;
jn.setParameter(i++, Type.STRING, ""+version);
jn.invoke();
ret = Integer.parseInt(jn.getRetVal());
System.out.println(jn.getRetVal());
} finally{
if (jn !=null){
jn = null;
}
}
return ret;
}
//测试用
public static void main(String[] args){
String v ="";
try {
mydll.GSC_GetDLLVersion(v);
System.out.println("version:"+v);
} catch (NativeException | IllegalAccessException ex) {

}
}
