Both methods, if successful, return one or more Applet objects to the caller. An applet can find another applet in the same HTML page by either using the getApplet method to look it up by name or using the getApplets method to find all the applets on the page. Using the AppletContext APIīefore I explain the alternative a2a-communication mechanism, I will briefly show how the getApplet and getApplets methods work. However, since the applets are located on different pages, the Java API in AppletContext will not help you develop the idea completely - but this tip will. You even plan to make wizards within the help system that can remotely point out things and perform tasks in the stock-market-trade applet. In addition, you want to make the help system change to the correct information/guides based on what the user is doing in the stock-trade applet (much like the paper clip in the Microsoft Office suite).
Your motive for that decision could be based on structural concerns of your Website or the need to always keep the help system on display. You also want the help system to be an applet and to be placed in a different browser frame than the stock-market-trade applet. You have just finished writing a nice stock-market-trade applet and decide to write an even nicer help system for it. Those security restrictions may have been designed that way for good reason however, the latter requirement limits the ways you can make interesting multiapplet interfaces featuring applet-to-applet (a2a) communication.
By using those functions, an applet can find other applets and invoke methods on them. The AppletContext class in the java.applet package contains the two member functions getApplet and getApplets.
