Hey,
Can someone give me a work-around sollution for this exception.

String[] folders;

			folders = getPathName(remoteFile).split("/");

			

			

			

			for(i = 1; i<folders.length-1; i++){				

				ftp.makeDirectory(folders[i]);

				ftp.changeWorkingDirectory(folders[i]);

			}

The exception is given at the line:
ftp.makeDirectory(folders[i]);

A null pointer means that a variable isn't defined or accessible.

Look to see where you defined ftp and make sure you have started an ftp connection and the makeDirectory method is available to you where its at.

yeah I know but I couldn't figure it out which one.
It turned out it was the ftp variable :P

Maby You should write this like that ;)

String[] folders;
folders = getPathName(remoteFile).split("/");

if(folders != null && folders.length > 0) {			
  for(i = 0; i<folders.length; i++){
    if(folders[i] != null) {				
      ftp.makeDirectory(folders[i]);
      ftp.changeWorkingDirectory(folders[i]);
    } else {
      /*Current folder (folder[i]) doesn't exist.*/
    }
  }
} else {
  /*Folders of array object is null or empty.*/
}

Have fun!
