title: There are similar projects to Java libraries like Apache Commons?
body: <p>I want to know if there are another projects to provide libraries for Java like the Apache Commons project. I got some useful things like Logging, ConnectionPool, Configurations, etc. from it, but maybe there is something that it won't cover.</p>
  
  <p>At the moment, I don't need anything specific, but only want to know if there are similar projects. I want to know this because I can be wasting my time in things that are already done.</p>
