I am using Glassfish V2 server and till now every thing was going fine. It was deploying the application as usual, but suddenly it has started to prompt a 503 error saying "unable to find context listener", "unable to find ****class", "unable to find persistence unit" and like this for all the classes. How should I correct this error?

503 error must be due to some error in your web app that you are deploying ( assuming all other HTTP services such as admin console is running fine on your server) Check what state the application is shown in admin console - that may give a clue.
