Java Me mimarisinin ilk katmanı olan profil katmanı,çeşitli konfigürasyon ayarları üzerinde çalışan farklı cihazların yazılımsal gereksinimlerini tamamlayan bir yapıdır.Java Me mimarisinde daha önceden bahsedilen konfigürasyon kavramı,cihazların donanımsal özelliklerine göre geliştirilen bir katman yapısı iken,profil katmanı ise daha çok cihazların yazılımsal gerekensinimlerine bağlı olarak geliştirilmiş bir katman yapısıdır.

Aşağıda Java Me mimarisinin katman yapısı gösterilmiştir.

Java Me Mimarisi

Java Virtual Machine
Operating System
Profil katmanı,bir Java me programına çeşitli kütüphaneleri,API'leri ve uygulamaları tedarik eder.CLDC(Connected Limited Device Configuration) ve CDC(Connected Device Configuration) konfigürasyonları için temelde 2 profil sağlayıcısı göze çarpmaktadır.

1.MIDP(Mobile Information Device Profile)
2.Personel Profile

MIDP profili CLDC konfigürasyonu üzerinde çalışan cihazlar için sağlanırken,Personel profili ise CDC üzerinde çalışan cihazlar için geliştirilmiştir.
