writing to jar file

[Joe McIntyre]

I'm developing a desktop app in NetBeans. Currently, when I run the program from within the NetBeans environment, it uses (I think) the build folder, which does not have everything packaged in a jar file. So I can write to any of those folders that correspond to package names in my application. But what will happen when I package the whole thing in a jar file for deployment? I can't write to a file that is stored in that jar file can I? Is there a standard solution for this problem?

Thanks.

No.

That depends on what you are trying to do.

Well, suppose I just want to save some application preferences... what would I do then?

[Joe Ess]

A good place to do that is in the user home directory.
You can get that through the java.lang.System.getProperties() method.

That sounds like a case for the Preferences API.
