Sending messages to other applets
- Thread starter outis
- Start date
Well there are two ways for Applets to communicate with each other.
One is if they are on the same HTML page (not differnt HTML pages in different frames) you need to name your applets in its HTML APPLET tag.
Then in the applet you want to access the above applet you would do the following:
You may need to cast the Applet object returned if you added additional methods to your class you need to access.
The only other way will be via a socket connection(RMI, or other network communication). If the applet is part of another HTML file then it will have to use a socket connection. If the applets reside on the same server then you should not have to worry about breaking the applet security sandbox. If they are not then they will need to be signed, or users local java.policy files changed to allow the functionality you need.
So if you do not have to use frames on your web page it would be easier.
Anyways I hope this helps...

My personal option is to never to frames. They were useful back in early versions of HTML but since HTML 3.2 Tables have become very powerful and robust that you can layout your page very nicely with out frames. Also if you are worried about saving time with repeate code like button banners, etc. You can use various CGI scripts, and other scripting languages that can dynamicly embed multiple html pages in to a single html page at the time the page is called. This way you only really have one file containing the html code, but it is shared among tons of pages. You get html code reuse

Applet myApplet = getAppletContext().getApplet("myApplet");The only other way will be via a socket connection(RMI, or other network communication).
