We have a very strange issue. All the time when we have a change that affects only one or two classes in our application we do a manual deploy. Basically, we copy the compiled classes into WebSphere deployment directory and restart the server. We never had any issues before. Last week we did the same thing for one class, lets say A. However, after we restarted the server, we didn't see a change. Checked the time stamp of the file, size, permissions - everything looked good. We removed the file, and restarted the server. The server didn't start complaining that it could not find the class A. Copied file again, restarted. Still - no change... Old information is show on the site. Restarted WAS with Verbose class loading enabled. Checked the path from there the file is loaded - it's correct. Not really sure what is going on. Have anybody had something similar ?
