title: Dynamic Web Module option in Eclipse
body: <p>Could someone please explain the purpose of this option and what exactly it is for. </p>
  
  <p>It looks like the default is on my eclipse installation is 3.0 but it wont run on a Tomcat 5.5 server and probably not Tomcat 6.0
  Is it related to the servlet spec that the Tomcat server supports? If so which version do i need to use for Tomcat 5.5 and Tomcat 6.0? </p>
  
  <p>And also, i think there is a link between the compiler version that i use and the web module version selected. Is there some kind of documentation that explains what this relationship is? </p>
  
  <h2>Edit</h2>
  
  <p>And also, why is it that if i select v2.4 web module, it defaults to JDK 1.4?</p>
  
  <p>Thanks</p>
