How to update Runtime?

[Grzesiek]

Hi,

In my program i have the lines:

Runtime.getRuntime().exec("java -jar app.jar");

/* Here is the code that changes app.jar*/

Runtime.getRuntime().exec("java -jar app.jar");

In the last line the old app.jar is invoked but i want the new one to
be invoked there. How can i update Runtime?

Thanx

It will automatically pick the latest jar. The time you get in trouble
with old jars in Applets. You must restart the browser.

You can also say

App.main( xxxx);

If you want to run in the same JVM. This will start much more
quickly, but won't let you change the implementation on the fly.
