Update data documents for JWS deployed app

Question

I have a swing application that uses many data files, these data files will change time to time. How can I load these data files on client's machine? Is there any way to create a folder like structure and run a batch file or so? Any help is appreciated.

Answer 1

There are several ways to do this:

1. Assume you want to ship your application with the datafiles, you may embed them as a zip/jar in your application-jar-file.
   
   Extract the embedded zip to a temporary local file and use ZipFileSystemProvider to extract the content to some place on the disc.
   
   Here is an example how to extract some content from zip/jar-file embedded in a .jar-file downloaded by JWS.

2. Same as 1, but skip the zip stuff and instead provide a list of all the resources you want to extract

3. One other way is to create the files pragmatically using either java.nio.file (java 7+) or java.io.File
