..I have a Java stand alone application, that I`m trying to deploy as a Java Web Start application, my application must have access to the local file system so that it can read an write files, I have googled around how to do this, and as far as I understand I`m supposed to
1.Sign all the jars.
2.Add the following lines to the jnlp file
     <security>
          <all-permissions/>
</security>That is correct for using classes such as JFileChooser/File, but the JNLP API (available to webstart apps.) allows even sand-boxed apps. to access the local file system. Here is a [demo of the JNLP file services|http://pscode.org/jws/api.html#fs].
I have done this but when the app tries to open a local forlder I get the following error:
Exception in thread "AWT-EventQueue-0" java.security.AccessControlException: access denied (java.io.FilePermission /home/fuanka/DicomSeries/8_1052380670_TC_ABD read)
So I still don`t have enough privileges to access the local file system, what am I missing?Have you validated the JNLP file? If not, use JaNeLA to validate it.
