Java中可以调用Com组件吗？

请给个例子！谢谢！

需要使用JNI方法，使用C语言编写一个DLL然后调用

[armyshu]

public class MACCode {

public static void main(String args[]) {

MACCode mac = new MACCode();
System.out.println("本机网卡MAC地址为 "+mac.getFormattedCode());
}

public native String getMACCode();

static {

System.loadLibrary("MACCodeDLL") ;
}

public String getFormattedCode() {

String code = this.getMACCode();
code = code.toUpperCase();
code = code.substring(0,2)+"-"+code.substring(2,4)+
"-"+code.substring(4,6)+
"-"+code.substring(6,8)+
"-"+code.substring(8,10)+
"-"+code.substring(10,12);
return code;
}

}
该例子为读取机子的网卡MAC地址，用到了WINDOWS的DLL库，在JAVA中调用时只需要将方法申明为native就行了

读取网卡的MAC地址，用到WINDOWS的DLL库，只要将方法申明为NATIVE就行
public class MACCode {

public static void main(String args[]) {

MACCode mac = new MACCode();
System.out.println("本机网卡MAC地址为 "+mac.getFormattedCode());
}

public native String getMACCode();

static {

System.loadLibrary("MACCodeDLL") ;
}

public String getFormattedCode() {

String code = this.getMACCode();
code = code.toUpperCase();
code = code.substring(0,2)+"-"+code.substring(2,4)+
"-"+code.substring(4,6)+
"-"+code.substring(6,8)+
"-"+code.substring(8,10)+
"-"+code.substring(10,12);
return code;
}

}
