Saya telah menginstal Oracle Java 7 sesuai dengan panduan ini.
Ketika saya menjalankan sudo update-java-alternatives -s java-7-oracle , itu memberi saya :

update-alternatives: error: no alternatives for xulrunner-1.9-javaplugin.so.
update-alternatives: error: alternative /usr/lib/jvm/java-7-oracle/jre/bin/jexec for jexec not registered, not setting.
update-alternatives: error: alternative /usr/lib/jvm/java-7-oracle/jre/lib/amd64/libnpjp2.so for mozilla-javaplugin.so not registered, not setting.
update-alternatives: error: no alternatives for xulrunner-1.9-javaplugin.so.

Ada apa?
Saya menggunakan ubuntu12.04 amd64.

Jawaban yang Diterima:

Properly installing Oracle java 7 JDK and JRE on Ubuntu 64Bits and beased distributions.

Menginstal Oracle java 7 JDK dan JRE dengan benar di Ubuntu 64Bits dan distribusi beased.

OPSI 1:Langkah demi Langkah

BUKA JENDELA TERMINAL (uxterm atau emulator terminal lainnya)

Jalankan sebagai root

sudo -i

cd /

Menjamin bahwa perintah “apt-add-repository” berfungsi (bug yang diketahui di beberapa 64bit Ubuntu, dan distribusi berbasis)

aptitude update

aptitude install python-software-properties

Instal Oracle java PPA

apt-add-repository ppa:webupd8team/java

Instal Oracle java

aptitude update

aptitude install oracle-java7-jdk oracle-java7-set-default oracle-java7-installer oracle-java7-plugin

Perbaiki masalah Oracle java:bagian 1. Buat direktori “/usr/lib/xulrunner-addons/plugins/”

mkdir -p /usr/lib/xulrunner-addons/plugins

Perbaiki masalah Oracle java yang diketahui:bagian 2. Daftarkan alternatif yang hilang

update-alternatives --install /usr/lib/mozilla/plugins/libjavaplugin.so mozilla-javaplugin.so /usr/lib/jvm/java-7-oracle/jre/lib/amd64/libnpjp2.so 1

update-alternatives --set mozilla-javaplugin.so /usr/lib/jvm/java-7-oracle/jre/lib/amd64/libnpjp2.so

update-alternatives --install /usr/lib/xulrunner-addons/plugins/libjavaplugin.so xulrunner-1.9-javaplugin.so /usr/lib/jvm/java-7-oracle/jre/lib/amd64/libnpjp2.so 1

update-alternatives --set xulrunner-1.9-javaplugin.so /usr/lib/jvm/java-7-oracle/jre/lib/amd64/libnpjp2.so

Perbaiki masalah Oracle java yang diketahui:bagian 3. Perbaiki lokasi file “jexec” di “/usr/lib/jvm/.java-7-oracle.jinfo”

sed -i '[email protected] jexec /usr/lib/jvm/java-7-oracle/jre/bin/[email protected] jexec /usr/lib/jvm/java-7-oracle/jre/lib/[email protected]' /usr/lib/jvm/.java-7-oracle.jinfo

Perbarui alternatif java untuk membuat Oracle java menjadi java default pada sistem

update-java-alternatives -s java-7-oracle

Copot pemasangan file java OpenJDK

aptitude purge openjdk-7-jre openjdk-7-jre-headless openjdk-7-jre-lib default-jre default-jre-headless icedtea-7-jre-jamvm

Logout dari pengguna “root”

exit

Tutup jendela terminal

exit

OPSI 2:SKRIP SATU KALI

BUKA JENDELA TERMINAL (uxterm atau emulator terminal lainnya)

sudo -i

cd /

aptitude update

aptitude install python-software-properties

apt-add-repository ppa:webupd8team/java

aptitude update

aptitude install oracle-java7-jdk oracle-java7-set-default oracle-java7-installer oracle-java7-plugin

mkdir -p /usr/lib/xulrunner-addons/plugins

update-alternatives --install /usr/lib/mozilla/plugins/libjavaplugin.so mozilla-javaplugin.so /usr/lib/jvm/java-7-oracle/jre/lib/amd64/libnpjp2.so 1

update-alternatives --set mozilla-javaplugin.so /usr/lib/jvm/java-7-oracle/jre/lib/amd64/libnpjp2.so

update-alternatives --set xulrunner-1.9-javaplugin.so /usr/lib/jvm/java-7-oracle/jre/lib/amd64/libnpjp2.so

sed -i '[email protected] jexec /usr/lib/jvm/java-7-oracle/jre/bin/[email protected] jexec /usr/lib/jvm/java-7-oracle/jre/lib/[email protected]' /usr/lib/jvm/.java-7-oracle.jinfo

update-java-alternatives -s java-7-oracle

aptitude purge openjdk-7-jre openjdk-7-jre-headless openjdk-7-jre-lib default-jre default-jre-headless icedtea-7-jre-jamvm
