So why when I specify a factory do I get an error. So I added the jar and now it works but I would like to have some information as to what on earth is going on because I am using the newest tomcat version.
So then I did a little bit of research on SO and found a post saying that you need to add this jar to your lib folder if you have an older version of tomcat. The reason I want to make sure that I have it is because in the apache tomcat tutorial it says factory is required, and the value should be .pool.DataSourceFactory This error only comes up when I have this statement in my context.xml file.

I am using this tutorial to set up pooling for JDBC. So I've figured out my error, now I'm just looking for some insight as to what is going on exactly.
