Java Programming

help~!

I got this error msg "java.lang.UnsupportedOperationException: Not yet implemented".

I was just trying trying to run my program that pick up information/records and to ftp to the ftp server.

Kindly advise.

PS/ i googled but could not find much info on this exception

Below is a small segment of my code on the ftp:

		if(haveRecord && haveAlert){
			    String filename = outFilePath+new java.util.Date().getTime()+"_"+outFileName;
    			aml.exportFile(filename);
    			    			
    			eventlog.writeln("Message list " + filename + " generated");
    			
    			eventlog.writeln("FTP " + filename );
    			DosCommander.exec("cmd /C ftpBatch ", eventlog);
    			eventlog.writeln("Move " + filename + " to archive");
    			System.gc();
    			DosCommander.exec("cmd /C moveFile \"" + filename +"\"", eventlog);
    			
			}else{
			    eventlog.writeln("No message for this round");
			    stopPoll();
			}
