Laporan Praktikum II | Membuat inventory barang menggunakan maven ecplise

Pada praktikum kali ini saya akan membuat aplikasi sederhana yaitu inventory barang menggunakan maven eclipse.

Sebelum kita menginstall eclipse, pastikan Sistem Operasi Linux kita telah terinstall jdk. Jika telah terinstall, Eclipse versi terbaru dapat di download di 

http://eclipse.org/ Berikut langkah-langkah instalasi Eclipse IDE. Download Eclipse, pilih versi sesuai dengan sistem operasi yang digunakan. Gunakan Eclipse IDE for Java EE Developer.

 

Setelah proses download selesai extract paket yang telah terdownload (instalasi Eclipse IDE tidak menggunkan wizard sama sekali). Kemudian jalankan Eclipse (secara umum eclipse.exe pada windows atau eclipse pada linux).

  Pilih workspace yang akan digunakan sebagai tempat penyimpanan proyek

 

Kemudian klik OK, maka eclipse IDE siap digunakan.

langkah selanjutnya menginstall lampp. perhatikan berikut ini

Download aplikasi lampp di http://dl-lokal.info

Setelah proses download selesai extrak paket lampp ke direktori /opt/. Caranya menggunakan perintah sudo tar xvfz Downloads/xampp-linux-1.7.3a.tar.gz -C /opt/ di terminal.

  Dan untuk menjalankan lampp tersebut kita menggunakan perintah sudo /opt/lampp/lampp start di terminal.

Sebagai permulaan, kita akan membuat cimande project untuk menampilkan form Admin Cimande, dengan langkah – langkah sebagai berikut :
Buat sebuah database dengan nama gampang.

• Buat Maven project dengan cara File → New → Other
• Pilih Maven → Maven Project, kemudian klik Next 
• Kemudian akam tampil New Maven Project, Klik Next 
  Klik Add Archetype untuk penambahan plugin cimande. Ketik sesuai gambar di bawah ini :
   
  • kemudian klik OK. Maka secara otomatis Eclipse akan mendownload plugin dari cimande.
  • Jika prosesnya telah selesai, Pada field Catalog pilih All Catalogs kemudian pada field Filter ketik org.blueoxygen sehingga otomatis GroupId, ArtifactId dan Version akan tampil. 
  • Pilih versio 2.0, kemudian klik Next
    Masukkan Group Id dan Artifact Id. Sebagai contoh:
    GroupId : org.blueoxygenArtifactId : myproject
    • Kemudian klik Finish
      Maka akan terbentuk struktur direktory dari cimande tersebut.
      
       Notice : Jika struktur direktory dari project cimande seperti gambar diatas maka pembuat project kita berhasil. Tetapi jika tidak maka tunggu beberapa saat karena eclipse tersebut sedang mendownload file – file yang dibutuhkan. Proses kita bisa lihat di Progress.
      
      

      • Buka file hibernate.properties kemudian edit sesuai dengan username, password, database yang telah kita buat tadi.

      
      

      

      •  Masukkan perintah untuk menggenerate table schema dengan cara klik kanan project → Run As → Maven Build. Isi Goals dengan perintah hibernate3:hbm2ddl
      • Untuk mengimport data table kedalam database gunakan  perintah
        initialize dbunit:operation
      • jalankan perintah tomcat:run, maka secara otomatis Maven akan mendeploy aplikasi ke dalam server serta menjalankan server. 
      • Setelah server berhasil dijalankan, proyek dapat dibuka melalui url http://localhost:8080/(namaproject). Masukkan username admin dan password blueoxygen untuk dapat masuk ke halaman wokspace administrator.
    
    
    
    langkah selanjutnya Buatlah 4 Package di folder src/main/java dengan nama sebagai berikut
