Solution to the problem faced while syncing data with excel using java applet

In previous posts, we saw java programs in which we used applet to sync the entered data in the excel sheet. But when you run the program, you would face problem while writing the data to the file and opening of the file using applet's button. So add:

grant{
permission java.security.AllPermission;
}

statement in java.policy (C:\Program Files\Java\jdk1.8.0_05\jre\lib\security)
file.
