Internet Explorer 3.0 can invoke the public methods of Java applets and can read and write the values of public fields of Java applets, in much the same way that Navigator 3.0 can. Although the underlying mechanism is different, the basic syntax is the same:
The data conversion that occurs when Internet Explorer passes values back and forth to Java follows ActiveX's rules, and is not documented here.
There are a couple of restrictions on IE 3.0 interactions with applets. First, note that it does not support the applets array of the Document object. So if you want to read or write properties or invoke methods of an applet, you must call the applet by name, and you must assign a name to the applet with the NAME attribute of the <APPLET> tag.
Third, Internet Explorer can only invoke the public instance methods of an applet. It has no mechanism for invoking with Java class methods.
