Contoh Java Web Program Servlet Membuat Form Registrasi
SERVLET
Servlet merupakan dasar dari teknologi java web, yaitu
sebuah class java yang memiliki kemampuan sebagai server. Servlet bekerja
berdasarkan model request-respone, dan dasar dari teknologi bersama JSP,
Seperti dilihat dari J2EE, Servlet termasuk komponen web container. Siklus hidup
sevlet terdiri atas 3 tahap , yaitu init(), service(), dan destroy()
Tahap init merupakan tahap awal dimana init() dipanggil web
container setelah servlet
diinisialisasi, kemudian web container memanggil metode servlet(). Pada tahap
ini servlet siap menunggu request untuk melakukan proses mengirim respon ke
client. Dan terakhir metode destroy , merupakan metode yang dipanggil , ketika
web container dimatikan
