AEM - Connection pooling for SQL Server

So, I am attempting to use the Day Commons JDBC Connection Pool feature of AEM to hit my SQL Server instance. I am getting the impression, based on the thread I have linked in (below) that it is not really possible?

http://help-forums.adobe.com/content/adobeforums/en/experience-manager-forum/adobe-experience-manager.topic.html/forum__tj7e-hi_im_tryingto.html

So, on my local instance I am getting the following error (on startup) even though I have the class in question loaded to the environment as part of an OSGi bundle.  Any ideas what might be going on and/or how to fix it?
