Hi All
can someone please help me on the error in my web application...
I am using tomcat , the path for index dir is obtained from jsp page using
application.getRealPath("/")+"download/compName"
I want to index when the file gets uploaded.
I am getting this error...
java.io.FileNotFoundException: C:\tomcat\webapps\myApp\download\compName\segmen

This directory C:\tomcat\webapps\myApp\download\compName\ exist in the file
