Question

Background

I’ve made a Java application that is started by downloading a dynamically generated .jnlp file. What the application does is not really relevant, but its a screenrecorder. The user will download and start several (maybe hundreds) of these applications over time.

Problem

When the program ends I would like to delete the jnlp file that started the application. The point of the program is that nothing should be installed and nothing left behind. That includes the jnlp filed that one download to start it.

Question

Is there a way to find the jnlp file so i can delete it? (Preferably a File object)

Answer 1

Look up system property var jnlpx.origFilenameArg and delete it from the java application.

This worked on Java 6 update 26.
