hi Ganesh,
the program still gives error in the second line . it says that *cannot
find symbol * .I think that we are initializing the object of Field class
two times, that is why we are getting error.
document.add(new Field("content",textReader));
document.add(new Field("path",textFiles[i].getPath()));
Thanks,
Nitin Gopi
