Rename a file (file upload in servlet) - file

Question

I'm trying to rename a file after upload but the error I get is:
File Upload Failed due to java.io.FileNotFoundException: C:\Users\Akhil\Documents\CryptographicSteganography\Image\toshaMon Dec 29 22:21:41 IST 2014.jpg (The filename, directory name, or volume label syntax is incorrect).
I went through almost all the possible related topics in stackoverflow as well as other sites but couldn't resolve this error.
my servlet class:
package FileUploadHandler;
import com.pointerunits.web.*;
import java.io.File;
import java.io.IOException;
import java.util.Date;
import java.util.List;
import javax.servlet.ServletException;

Sorry about that awful lot of comments:
my program was going through a testing phase

Answer 1

May be there is right issue, it cannot access the folder as it does not have right.
If this is not the case then.
You should try to remove space from the file name format data value to a format that does not contains any space Sample Format Date . Because space can create problems.
Before item.write(uploadedFile); check
if(!uploadedFile.exists()){
uploadedFile.createNewFile();
}
