IGOS Nusantara dan Sun Java

Beberapa aplikasi berbasis web yang memakai Java tidak dapat jalan jika memakai OpenJDK, sehingga harus memasang Sun Java JDK atau JRE.

Unduh JRE

Unduh Sun Java JDK atau JRE (saat ini JDK 6 Update 18) dari http://java.sun.com/javase/downloads/index.jsp

Unduh berkas rpm.bin (contoh jdk-6u18-linux-i586-rpm.bin).

Pasang

Misal berkas disimpan pada direktori /tmp

# cd /tmp
# chmod 755 jre-6u18-linux-i586-rpm.bin
# ls -l jre*
  -rwxr-xr-x  1 jr   jr    20505673 Des 22 00:23 jre-6u18-linux-i586-rpm.bin
# ./jre-6u18-linux-i586-rpm.bin

Ubah OpenJDK ke Sun JDK

Jika sebelumnya telah memasang OpenJDK, maka sistem harus diubah agar memakai Sun JDK, lakukan:

alternatives --install /usr/bin/java java /usr/java/jdk1.6.0_18/bin/jre/java 20000
alternatives --install /usr/bin/javaws javaws /usr/java/jdk1.6.0_18/bin/jre/javaws 20000
alternatives --install /usr/lib/mozilla/plugins/libjavaplugin.so libjavaplugin.so /usr/java/jdk1.6.0_18/jre/lib/i386/libnpjp2.so 20000

Jika memasang JDK, sesuaikan javac

alternatives --install /usr/bin/javac javac /usr/java/jdk1.6.0_18/bin/javac 20000

Konfigurasi Google Chrome

# mkdir /opt/google/chrome/plugins
# cd /opt/google/chrome/plugins
# ln -s /usr/local/jre1.6.0_18/lib/i386/libnpjp2.so .

atau:

# ln -s /usr/java/jre1.6.0_18/lib/i386/libnpjp2.so /opt/google/chrome/plugins/

$ google-chrome --enable-plugins %U 

Control Panel

# /usr/java/jre1.6.0_18/bin/ControlPanel
