Isso não é verdade!!! existem alguns benchmarks (esqueci aonde)
indicando que java (utilizando HotSpot) pode ser mais rápido do que apps
em Visual C ou Visual Basic.

É mentira tb. Seu cellular provavelmente roda Java ! se não seu
cellular, no futuro sua geladeira.

Tem, a sua portabilidade e a sua standardização. Java em sua maioria são
especificações (JCA, J2EE, JDBC, JAXP e muito mais).

Então vc não procurou bastante, Q vc acha de DB2 ou Oracle.. Não são
produtos sérios ????

Se vc não quer uma solução escalavel, vai com PHP ou ASP se vc quer uma
coisa sério, use J2EE assim como 80% dos fortune 500 (sim 80% do fortune
500 use j2ee (weblogic).

Poizz eh, e Solaris ?? HP-UX ?? Tru-64 ?? AS400 ?? tem delphi ou VB para
estes maquinas ??? A e, falando nisso... www.itauseguros.com.br
(weblogic personalization server),. Trocou de ASP para j2ee pq os
corretores não aceitaram mais que o site ficou sempre fora do ar ...

Procura e vc achará !!!! usuários J2ee...

O Bill Gates falou em 87 "Ninguém nunca precisará mais do que 640 K de
ram" ae a especificação de Win XP 128 MEGA de RAM.
Java não necessariamente é a melhor linguagem para criar UI pois o swing
certamente é lento Mas o que precisa depende dos requisitos de projetos.
Amazon troucou para Java porque asp não aguentou.
