# Hot Deployment in a non-CMP Application

Previous

Next

When you take advantage of hot deployment in a non-CMP application, you must refresh the TopLink session using the `SessionManager` method `getSession` with the appropriate arguments (see "Refreshing a Session When the Class Loader Changes".

If you do not use this `SessionManager` method, then your application is responsible for destroying or refreshing the session when a hot deployment (or hot redeployment) occurs.
