title: Java EE capabilities into Eclipse-Classic or Flex Builder 4.6
body: <p>There is a Flex lib which only compiles within FB4.6.
  I tried using FB4.6 Eclipse plugin, but It doesn't compile within Eclipse 3.6.x or 3.7.</p>
  
  <p>So I installed Java EE plugins (not exactly sure) into FB4.6.
  But it doesn't give exact Java EE capabilities within FB4.6 (It doesn't behave as Eclipse-Java EE). 
  For example I couldn't install the JSP editor.</p>
  
  <p>Is there a way to upgrade FB4.6 to Java EE? </p>
  
  <p>OR </p>
  
  <p>Eclipse-Classic to Eclipse-Java EE?</p>
