if you use association tag in jnlp file to associate a specific file type to the jnlp application, whenever you double click on that file, java web start will invoke the jnlp application to handle the file.

however when the application needs to open the file, it will pop up the security dialog again if application is running in sandbox.

since the user already indicated that he wants to open the file by double clikcing on it, the jnlp application should at least have read access to that file in this case by default
