О Великий форум!
У меня возникла такая проблема с JNI:
| Код |
public class ComPort
{
//-----------------------------------------------------------------
static
{
System.loadLibrary("ComPort");
}
//-----------------------------------------------------------------
public native int showMessage(); // - любопытства ради
private native int closePort(int port);
//-----------------------------------------------------------------
public int portClose(int port)
{
int i=0;
try{i=closePort(port);}catch(Exception e){System.out.println("(Java::CommPort) Err:closePort("+port+")");}
return i;
}
//-----------------------------------------------------------------
public static void main(String[] str)
{
int i;
int numPort = 4;
ComPort comPort = new ComPort();
i=comPort.showMessage(); System.out.println("(Java::ComPort) showMessage value: \t"+i);
i=comPort.portClose(numPort); System.out.println("(Java::ComPort) port is closed? \t"+i);
}
//-----------------------------------------------------------------
|
в результате имею ВОТ ТАКУЮ ошибку, млин:
| Код |
(Cpp::ComPort) it's message!
(Java::ComPort) showMessage value: 1
Exception in thread "main" java.lang.UnsatisfiedLinkError: closePort

вот нативный код [header]:
| Код |
/*
* Class: ComPort
* Method: showMessage
* Signature: ()I
*/
JNIEXPORT jint JNICALL Java_ComPort_showMessage
(JNIEnv *, jobject);
/*
* Class: ComPort
* Method: closePort
* Signature: (I)I
*/
JNIEXPORT jint JNICALL Java_ComPort_closePort
(JNIEnv *, jobject, jint);
|
вот нативный код [source]:
| Код |
//------------------------------------------------------------------------------
JNIEXPORT jint JNICALL Java_ComPort_showMessage(JNIEnv *, jobject)
{
printf("(Cpp::ComPort) it's message!\n");
return 1;
}
//------------------------------------------------------------------------------
JNIEXPORT jint JNICALL Java_CommPort_closePort(JNIEnv * jenv, jobject jobj, jint port)
{if(!init) Init();
return ClosePort(port);
}
//++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
unsigned int ClosePort(unsigned int port)
{if(!comport) return PORT_CLOSE;
printf("(Cpp::ComPort) close port: \t%d\n",port);
try{if(comport->CloseCOMport()!=PORT_CLOSE) {printf("(Cpp::ComPort) Can't close this port: \t%d\n",port); return PORT_ERROR;}}
catch(...){printf("(Cpp::ComPort) Exeption: closing port: \t%d\n",port); return PORT_ERROR;}
comport=0;
return PORT_CLOSE;
}
//++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

а самое обидное то, что пока я не влез дорабатывать эти исходники (которые сам и писал) оно работало, ёпрст

И спасибо всем
