Run jar from eclipse vs. browser

Is there any difference between running a project that is packed as a jar file from within eclipse(where it works fine) and running the resulted jar file from within a browser.

The project consists of an applet which is pac开发者_开发百科ked into a jar called from an html page.

I should mention that the jar file is signed.

Thanks.

When running a project in eclipse, by default all security privileges are granted. When running an app in a browser there will be security restrictions that will not allow your program to run correctly. Also check your manifest file in the jar and see if it is configured correctly.
