.not able to comprehend why i m getting this error.. I want some filters in a excel file to which i load data and send it to client. in the server process.i get an existing file(a template) which exists in my class path. im using getResourceAsStream for this. i create a work book with this stream. i get this error evry time. it used to work fine earlier. what i cud notice is if i change this template i.e make some modifications in the column names etc . and save and copy it to classpath with maven .. Im getting this error.. if i again get the old version of the template i dont get the error. What can i do here?? please help...
