In this section we explained how the generic JWAVE applet, JWaveApplet, can be used to create client applications that use PV‑WAVE as a numerics and graphics server. The generic applet allows you to use JavaScript functions to control the applet and pass data and parameters between the client and server. Rogue Wave has provided several sample applets that you can run and examine on your own. Feel free to reuse these applets and their helper functions for your own applications.
