I am trying to read portable devices from java signed applet.... I found a jmtp library on http://code.google.com/p/jmtp/w/list to get access to portable devices but when i run it in netbeans it gives error
Exception in thread "main" java.lang.UnsatisfiedLinkError: no jmtp in java.library.path at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1860) at java.lang.Runtime.loadLibrary0(Runtime.java:845) at java.lang.System.loadLibrary(System.java:1084) at jmtp.PortableDeviceManagerImplWin32.(PortableDeviceManagerImplWin32.java:38) at jmtp.PortableDeviceManager.(PortableDeviceManager.java:34) at jmtp.Jmtp.main(Jmtp.java:23) Java Result: 1
I searched and found that i have to include .dll file as native library in project of jmtp... I right-clicked on project and navigated to properties and then Selected "Run" and Selected VM Option as
-Djava.library.path="c:\jmtp\native\windows"and placed that jmtp.dll file in c:\jmtp folder
But same error appears constantly my code is
package jmtp;
import jmtp.PortableDevice;
import jmtp.PortableDeviceManager;
import jmtp.PortableDeviceObject;
import jmtp.PortableDeviceStorageObject;
public class Jmtp {
public static void main(String[] args) {
PortableDeviceManager manager = new PortableDeviceManager();
PortableDevice device = manager.getDevices()[0];
// Connect to my mp3-player
device.open();
System.out.println(device.getModel());
System.out.println("---------------");
// Iterate over deviceObjects
for(PortableDeviceObject object : device.getRootObjects()) {
// If the object is a storage object
if(object instanceof PortableDeviceStorageObject) {
PortableDeviceStorageObject storage = (PortableDeviceStorageObject)object;
for(PortableDeviceObject o2 : storage.getChildObjects()){
System.out.println(o2.getName());
}
}
}
manager.getDevices()[0].close();
}
}
please, tell me what is the issue
Finally i found the solution, In order to include native library we need to add following steps in netbeans
==>Right click on the Project ==>Properties ==>Click on RUN ==>VM Options : -Djava.library.path="C:\Your Directory where Dll is present" ==>Ok
