Suppose we have an applet on a webpage and JQuery code in the same page, as well. How can we notify JQuery upon an Applet action, for instance a timer in the applet stops and a file system change occurs, and i want to make some process upon this file change in JQuery part as soon as the change occurs. Any suggestions / solutions? Thanks.
You can start with short article: Java - Javascript interaction.
And then see Java-to-Javascript Communication and JavaScript to Java Communication (Scripting) for more info.
