Uploading problem on java ................

Question

HI
I have written a java code, which upload Files into tomcat server and file path will be store in DB Table .
I can able to upload file which is less then 100kb and code is working fine and file is storing properly on tomcat srevre and path is storing in DB table  .
Problem is when we try to upload file size more then 100kb then the same code is not able to coonect the database on Production server(i mean on hosting server in which we have hosted our website ) ....
Please let me know why code is not connecting to the databse only on when the  file size is exceeds 100kb .+
i am sure if it connects Database then file will definitely uploads into server

Answer 1

HI ,
The below code is working fine in local system for Different File sizes .
when we upload same code on hosting server or production server its not working fine .
As i said you if file exceeds more then 100kb then its not uploading into hosting server or production server and not even uploading entry in database Table .
**The Problem we are getting only if the file exceeds more then 100kb size on production server or hosting server only **
The below code which we used will performs , it takes Form fields such as Filaname,Type of Hoarding , dimenssion ,and uploaded file ...etc .All thease fields will store in Database table and file will store in server .
