This week's book giveaway is in the Mac OS forum. We're giving away four copies of a choice of "Take Control of Upgrading to Yosemite" or "Take Control of Automating Your Mac" and have Joe Kissell on-line! See this thread for details.
You will find it in the commons-dbcp-1.x.x.jar file avaialable here.
Having said that, it is my strong belief that it is not a good idea to use the Struts DataSource utility. You are better off defining your DataSource as a JNDI resource using Tomcat's interface and then doing a JNDI lookup for the DataSource in your code.
