System and method for enabling dynamic class reloading in an application server environment. A distinction is made between“versionable”and“non-versionable”classes. Versionable classes are classes that should be automatically reloaded when they are modified. The application server(s) may execute a background task that executes periodically to check for modified versionable classes. Users may specify class versionability by specifying a list of explicitly versionable classes, specifying a list of superclasses whose extending classes should be considered to be versionable, and specifying a list of interfaces whose implementing classes should be considered to be versionable. Once the background task discovers a modified versionable class, the background task may cause the class to be reloaded, e.g., by instantiating a new classloader and instructing the new classloader to reload the class. The background task may purge the reloaded class from any caches that the application server maintains.
