Tugas kedua Pemrograman Jaringan adalah membuat aplikasi mengirim dan menerima SMS menggunakan Sun Java Wireless Toolkit 2.5.2 .
Jika Anda belum punya Sun Java Wireless Toolkit 2.5.2, silahkan download disini .
Ikuti langkah - langkah dibawah ini :
1. Kita jalankan dulu Sun Java (TM) Wireless Toolkit 2.5.2_01 for CLDC. Setelah itu, klik New Project,di ProjectName kita ketikkan nama project kita, misalnya KirimSMS, di MIDlet Class Name ketikkan tulisan yang sama, Lalu klik Create Project.
2. Kita buka notepad++, ketikkan source code. (bisa dilihat setelah langkah-langkah ini) kemudian simpan sebagai .java .
3. Di sini, kita klik Build untuk mengetahui apakah program yang kita buat sudah benar atau belum. Jika masih terdapat kesalahan maka perhatikan kesalahannya pada baris kesalahan dan lokasi kesalahan yang ditunjukan pada layar konsul. Perbaiki kesalahan program tersebut hingga selesai simpan dan ulangi Build kembali. Setelah proses build selesai jika tidak terdapat kesalahan, klik Run. Kita bisa coba jalankan aplikasi buatan kita.
Langkah selanjutnya adalah membuat Package. Untuk menjalankan aplikasi ini di handphone kita harus membuat file .jad , file inilah yang nantinya akan kita pindahkan ke handphone dan kita instal di handphone.
Langkah-langkah pembuatan file .jad
1. pilih Project
2. pilih Package
3. pilih Create Package
Maka file .jad akan tercipta, dan file tersebut disimpan di dalam direktori bin.
