If I got it right, the txt file that I should add to the manifest file has to look something like this: (using this tutorial:How do I fix "missing Codebase, Permissions, and Application-Name manifest attribute" in my JNLP app?)
Permissions: kind of permission
Codebase: the path to my project files
Application-Name: my applet's name
I understood why the first two lines are needed, but I didn't understand the third one and I couldn't find it on google, what is it used for? if it doesn't have to be any file's name, and it is not seen by the end user what is it good for? and something else I'm not sure about, if I'm making an applet, should it be "Applet-Name" instead of "Application-Name"?
