I recall an old thread where people stated that some blogging platforms (WordPress?) didn't allow using Java applets in the article, but they might have found workarounds.
If you have access to the source of your article, open the .html file generated by the export function, and copy the whole part between <div id="content"> and the last </div> (including these tags) in the article at the location where you need the applet. You might want to change the id if it conflicts with the page (eg. rename it "Processing_content" or "my_sketch_name_content").

PS.: that's not a syntax question (not the syntax of Processing at least!), you should have put it in the Integration section instead).

I would be wary of sending people to a blog with loads of java applets running on it. It would choke your machine as soon as you visited it and the user would wonder what the hell was going on with their machine whilst the page is taking ages to load.

I would recommend using javascript to write the applet to the page when you click a link, which would be much more user friendly.

I tried out such a method here:

But applet object by fjen should be able to do the same as well.
