IGOS Nusantara dan Sun Java versi 1.6

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

Unduh Sun JDK atau JRE

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

Unduh berkas rpm.bin

• jre-6u18-linux-i586-rpm.bin ukuran 20.505.673 byte
• jdk-6u18-linux-i586-rpm.bin ukuran 80.314.190 byte

Pasang Sun JRE

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 ke Sun JRE

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

# alternatives --install /usr/bin/java java /usr/java/jre1.6.0_18/bin/java 20000
# alternatives --install /usr/bin/javaws javaws /usr/java/jre1.6.0_18/bin/javaws 20000

Plugin ke Firefox

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

Plugin ke Google Chrome

# mkdir /opt/google/chrome/plugins
# cd /opt/google/chrome/plugins
# ln -s /usr/java/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

Pasang Sun JDK

Misal berkas disimpan pada direktori /tmp

# cd /tmp
# chmod +x jdk-6u18-linux-i586-rpm.bin 
# ls -l jdk*
  -rwx--x--x 1 jr jr 80314190 Des 22 00:23 jdk-6u18-linux-i586-rpm.bin
