Try changing into the directory "bhagya/datta" and then listing the current directory.

i have taken basePart  at run time so it is not required to in this "bhagya/datta" format,here  i just mentioned run time value of  basePart.so please help me
commented Jan 10 by support2 (144,210 points)
Instead of calling dir("bhagya/datta" ) or whatever it is, change into that directory first and then call dir().

See following log after using chdir() method

By the looks of this command "LIST bhagya/datta" you are calling dir("bhagya/datta") instead of dir().
commented Jan 16 by Dattatray Satpute (140 points)
no, i am using this=> String str[]=proFTPClientInterface.dir();

Please post the code that is producing this output.
