Java Rich Internet Applications Guide > Enhancements and Other Features > Applet Persistence API

Two methods in the interface java.Applet.AppletContext enable applet persistence across browser sessions:

• setStream(String key, InputStream stream)
• getStream(String key)

These methods enable you to stream data and objects from one browser session so that they can be reused in subsequent browser sessions. This provides applet persistence and makes it unnecessary to use static objects in applets for this same purpose.

setStream(key, stream) maps a key to a stream. getStream(key) returns the stream mapped to the key. If the AppletContext already has a stream mapped to the key when setStream(key, stream) is invoked, the mapping is updated.
