Replace class in deployed EAR

[Bryce Martin]

I'm not sure where to put this question so if it doesn't belong here just move it.

I have a deployed EAR on our server. It has been well over a year since I have worked with this particular project but recently realized that I needed to retype a couple of variables from float to double to stop an overflow math issue. I need to put this updated class into the EAR and was wondering if I could just replace the current class with my updated one without any issues? I don't have a way to test this as this is deployed in production and I'd like to avoid any hiccups if possible. Can I do this "hot swap"? Will I have to restart the server or will the application pick up the new class upon the next use of the application?

Thanks for any pointers.

So after doing some more looking around I thought that I might give it a try. And it worked! As long as you have the class compiled at the same level as the deployed EAR you can replace a class of the same compile level in the war file.
