I mean.... I don't know myself, but it's a pretty general question.

You need to call a remote function on a different page via ajax?

What's a class file?

Do you mean a .js file?

If so, as long as the file is available to the page, you may use its functions. You can also use the DOM to make the file available. There are scripts here on DD (and probably elsewhere) that (among other things) 'load' .js files on a page.

See:

These scripts do this by creating a script tag element, assigning the .js file as its src attribute, and attaching it to the head element of the page. Although these actions are used with scrips that also use AJAX to load content, this part (loading a script) is purely a DOM operation.

What's a class file?

A class file is a file containing a Java class.

melvinoyh: Is it a server-side or a client-side class? Should it be used in an applet, or a servlet?

Geez, I knew that. I got so used to folks saying java and meaning javascript, I thought this was the case here. After all, this is the javascript forum.

Unfortunately, we haven't a Java forum.

Anyways, the OP may still be able to write a tag for the class using the DOM. In fact, with IE these days, any sort of object/embed is best done that way or with innerHTML or document.write (for this, all of these are best run from an external .js file) to avoid the 'click to activate this control' 'security feature' that MS recently added - not their finest hour.

Not if it's a server-side JSP page, to which I believe s/he is referring. There is no other reason to use AJAX, or to want to simply call a function and do nothing with the result, of which I can think.

Not their lowest, either

Well, let's not get too excited until we find out what the reason(s) is/are and what type the class is.

its a java class file that contain java function.
yes, its a server side JSP page that have AJAX use POST method to post data to server and call the function in the java class file to perform some processing and return back the processed info back to jsp page...
how to do so?
