java使用JNI调用动态文件dll,报错，在线等！

[jfashionjh]

函数名称：
JT_GetIDCardInfo(
HANDLE devNo,
char* Name,
char* Sex,
char* Nation,
char* Birth,
char* Address,
char* ID_Number,
char *IssueDepartment,
char* ValidingLife
);


java代码：
package test;

public class TestCard
{
// private native static String[] JT_GetIDCardInfo(char Name,
// char Sex,
// char Nation,
// char Birth,
// char Address,
// char ID_Number,
// char IssueDepartment,
// char ValidingLife);
// 首先定义指针，开辟内存空间，这里的内存空间根据返回的字符串来决定
private native static byte[] JT_GetIDCardInfo(byte[] Name,
byte[] Sex,
byte[] Nation,
byte[] Birth,
byte[] Address,
byte[] ID_Number,
byte[] IssueDepartment,
byte[] ValidingLife);

static {
System.loadLibrary("mcr03hid"); // 该动态库名称为中间动态库，由java程序使用，负责调用需要使用的动态库。

}

/**
* @param args
*/
public static void main(String[] args) {
System.out.println(JT_GetIDCardInfo(new byte[20],new byte[20],new byte[20],new byte[20],new byte[20],new byte[20],new byte[20],new byte[20]));
}
}
