How to implement an eclipse VM argument in code

问题

This is probably a simple question but I'm currently working with vlcj to make a video player for a project. I have a basic player working but only when I have the VM arguement

-Djna.library.path="C:\Program Files\VideoLAN\VLC"

defined in the debug configurations window. My question is if I need to create a version of this project to run outside of Eclipse do I need to define this argument in my code or will my program run in this way without problems indefinitely?

Thanks to anyone who answers,

Jared.

回答1:

I think

System.getProperties().setProperty("jna.library.path",
  "C:\\Program Files\\VideoLAN\\VLC");

should do the job in code for this particular case. -D arguments to java set system properties, which end up in System.getProperties().

You can't set JVM arguments at runtime, if you are going to export your project you'll have to find another way to do it: this is done by wrapping the execution of your program within a script file, let it be a .bat or .sh so that you can invoke the java executable with your paramters set.

I'm assuming you are talking about executing the program outside Eclipse.
