What is the main advantage that J2EE has over other languages?
Technically J2EE is not a language; it is a group of specifications, frameworks, technologies, etc. for building distributed enterprise systems. J2EE is comprised of a number of programming and scripting languages including Java, XML, JSP, HTML, SQL, and others. Some of the advantages of J2EE include cross-platform portability, availability of open-source libraries, a huge server-side deployment base, and coverage for most W3C standards.
