HTML Exports from Version 4.2
• In GeoGebra 4.2, html exports went to a file
on your local computer. This one file included
everything needed to run the applet.
• Security problems with Java have led to
updates for it. Under the newest Java, the
older GeoGebra html files may not work.
• GeoGebra 4.4 addresses these concerns by
using HTML 5
GeoGebra 4.4 for Desktops and
Notebooks
• Html exports now go to GeoGebraTube
• Links on local web pages point to your pages
on GeoGebraTube
• Java is not needed on the client computer (on
some networks, Java is either disabled or
security settings prevent its working with old
local html exports).
An Example
Here’s a web page with examples that illustrate
the key points:

m-2014-links.html
Try each one and give them time to load (or not
load).
Error Message from 4.2 Unedited Export
This appears under Tarleton’s network security settings for IE.
Message with the Edited 4.2 Export
This appears before the GeoGebra applet loads and runs.
The third example will load without any warnings. Allow
some time. A newer/updated browser is needed (I used IE
10 and Firefox 10.0.4).
BUT WAIT, THERE’S MORE…
If you have a tablet with a browser that supports HTML 5,
you can run the third example.
In the next slide, we show a screenshot from a Kindle Fire
HD running its native browser Silk. This browser does not
support flash.

JUST ONE MORE THING …
The 4.4 Export Works on Smart Phones
• Android (Moto X)
• iPhone 4S
And… (wait for it)…
the html file produced in GeoGebra 4.4 has
also been observed to successfully load and
work on an iPad Air.
