I've been experimenting with embedding Google Gadgets in Jive with mixed results and thought I'd share my findings.
I began by looking at the gadgets offered by Google and found two "versions" available. The first is those intended to be used with iGoogle (Add gadgets to your homepage - Google) and the second is those usable in your own web pages (Google Gadgets For Your Webpage).
You can find lots of interesting gadgets intented for iGoogle and some of them are usable directly withing Jive and some do not work at all. It's very hit and miss. I simply viewed the source of the Google page and found the XML file link. You just copy that link and paste it into the dev console to see if it'll run or not. The NY Times is one that works very well in Jive; You can then deploy it to your users like you'd normally do.
Many of the others do not work this way as they seem to have a higher dependancy of Google. Google Calendar is a good example of this type of gadget. I could not get it to work directly using the XML file technique. But Google provides a version of that intended to be embedded in your own webpage. Following the "Get the Code" link for the Google Calendar; it'll generate the code below you can embed in your own webpage.
Looking at that code it appears that the gmodules section provides the extra magic ingredient that is necessary to run the Gadget ourside the iGoogle framework. Would it be possible to take that code and use it in Jive? You bet!
Create a simple Jive app and simply embed that line of code in it. Here is the "home.html" file; it's that easy.
<link rel="stylesheet" href="stylesheets/main.css" type="text/css" media="screen" />
And if by magic, you can get Google Calendar and Docs running as Jive Apps.
I should note that these gadgets pick up your Google login information through the session so you must have been logged into Google for it to work for you.
Try it our and post how it works for you and what interesting gadgets you got working.
