Lei tu mensaje pero no logre ver si sabes Java SE o no.
Esa seria la primer pregunta, ¿Tienes conocimiento de Java SE? Necesitas eso primero ya que Java EE (ya no se llama J2EE) es una extension de Java SE, asi como Java ME es un subconjunto de Java SE.
Java SE es la base para los desarrollos en Java.
Cita: The name of the Java platform for the enterprise has been simplified. Formerly, the platform was known as Java 2 Platform, Enterprise Edition (J2EE), and specific versions had "dot numbers" such as J2EE 1.4. To strengthen the association with the Java platform, the short name is now Java EE, and to simplify the version number, the leading "1." is dropped. So the latest version of the Java platform for the enterprise is Java Platform, Enterprise Edition 6 (Java EE 6).
