title: How to install Java SDK on CentOS?
body: <p>I have <a href="http://en.wikipedia.org/wiki/CentOS" rel="noreferrer">CentOS</a> 5, but I don't know the steps to install Java SDK on Linux.</p>
  
  <p>Where to download the RPM file and what can I do next to fully install that?</p>
  
  <p>Then I need to install <a href="http://en.wikipedia.org/wiki/Apache_Tomcat" rel="noreferrer">Tomcat</a>.</p>
  
  <p>Or is there any ready-made package for all?</p>
