Applets can find other applets and send messages to them, with the following security
restrictions: Many browsers require that the applets originate from the same server. Many browsers further require that the applets originate from the same directory on the server (the same code base). The Java API requires that the applets be running on the same page, in the same browser window. Note: Some browsers let applets invoke methods on other applets - even applets on different pages in the same browser -- as long as all of the applets come from the same code base. This method of interapplet communication isn't supported by the Java API, so it's possible that it will not be supported by all browsers. An applet can find another applet either by looking it up by name (using the AppletContext getApplet method) or by finding all the applets on the page (using the AppletContext getApplets method). Both methods, if successful, give the caller one or more Applet objects. Once the caller finds an Applet object, the caller can invoke methods on the object. |
