The term J2EE is deprecated since 2006. The meaning has never changed: it’s still Java for the enterprise. But, it’s officially rebranded:
“The platform was known as Java 2 Platform, Enterprise Edition or J2EE until the name was changed to Java Platform, Enterprise Edition or Java EE in version 5.”
So it’s J2EE only until 1.4, but Java EE from 1.5 onwards, dropping the “1.” prefix.
