Hi All,

import org.sf.feeling. swt.win32.exten sion.hook.Hook;
import org.sf.feeling. swt.win32.exten sion.hook.data. HookData;
import org.sf.feeling. swt.win32.exten sion.hook.data. MouseHookData;
import org.sf.feeling. swt.win32.exten sion.hook.liste ner.HookEventLi stener;

public class HotMouse
{

public static void main(String[] args) {
Hook.MOUSE.addL istener(new HookEventListen er() {
public void acceptHookData( HookData hookData) {
if (hookData != null)
{
System.err.prin tln(((MouseHook Data)hookData). getPointX()"," ((MouseHookData )hookData).getP ointY());
}
if (hookData.getWP aram() == 513) { System.out.prin tln("left button pressed");// left button pressed
} else if (hookData.getWP aram() == 514) { System.out.prin tln("left button released");// left button released
} else if (hookData.getWP aram() == 516) { System.out.prin tln("right button pressed");// right button pressed
} else if (hookData.getWP aram() == 517) { System.out.prin tln("right button");// right button
} else if (hookData.getWP aram() == 519) { System.out.prin tln("middle button 519");// middle button
} else if (hookData.getWP aram() == 520) { System.out.prin tln("middle button 520");// middle button
}
}
});
Hook.MOUSE.inst all();
}

}


I have Used SWT Win32 Extension 1.0.5 toolkit for Mouse & Keyboard hook operation, in java.
I am using Eclipse J2EE Latest version, I also added those external jar files(SWT Win32 Extension all Jar files),
At design time I did not get any error when I run this program.


When I Run this Program I got the error as

Exception in thread "Thread-0" java.lang.Unsat isfiedLinkError : no swt-extension-win32 in java.library.pa th

What might be the problem ? and what can be done. any solution.

@Ganesh9u
I never used SWT but that error message indicates that a .so (or .dll) file could not be found for loading; the jvm wants to load the file 'swt-extension-win32' but can't find it anywere on the path 'java.library.p ath' designated for dynamic link libraries.

kind regards,

Jos
