I recently downloaded Eclipse IDE for Java Developers. But i actually require Eclipse IDE for Java EE Developers. Is there anyway to convert the existing IDE to Java EE Developer's IDE without downloading the entire Java EE Developer's IDE?
Have a look at the Compare Eclipse Packages chart. The first column shows what is included in Eclipse for Java, the second is for the JEE package. I would start from adding (installing with the Update Manager using an update site) WTP and Datatools.
