Oracle keeps on making it hard to install java directly. On gentoo system if you do:
Which means you need to hit their webpage directly and download the "exact" version of the jdk, then copy it to the specified directory, to proceed with the installation.
This is really pain. Alternativley you can download the JDK directly, and place it any where you want. Now to make it avaialble through "java-config", there's additional work needs to be done.

- cd to /usr/share/java-config-2/vm
- Create a file indicating the name and version of the jdk you want to manage through java-config. For example oracle-jdk-1.7
- Copy the following into the file:
VERSION="Oracle JDK 1.7.0_67" JAVA_HOME="/opt/jdk1.7.0_67" JDK_HOME="/opt/jdk1.7.0_67" JAVAC="${JAVA_HOME}/bin/javac" PATH="${JAVA_HOME}/bin:${JAVA_HOME}/jre/bin" ROOTPATH="${JAVA_HOME}/bin:${JAVA_HOME}/jre/bin" LDPATH="${JAVA_HOME}/jre/lib/i386/:${JAVA_HOME}/jre/lib/i386/native_threads/:${JAVA_HOME}/jre/lib/i386/xawt/:${JAVA_HOME}/jre/lib/i386/server/" MANPATH="${JAVA_HOME}/man" PROVIDES_TYPE="JDK JRE" PROVIDES_VERSION="1.8" # Taken from sun.boot.class.path property BOOTCLASSPATH="${JAVA_HOME}/jre/lib/resources.jar:${JAVA_HOME}/jre/lib/rt.jar:${JAVA_HOME}/jre/lib/jsse.jar:${JAVA_HOME}/jre/lib/jce.jar:${JAVA_HOME}/jre/lib/charsets.jar" GENERATION="2" ENV_VARS="JAVA_HOME JDK_HOME JAVAC PATH ROOTPATH LDPATH MANPATH" VMHANDLE="oracle-jdk-1.7" BUILD_ONLY="FALSE"
you will need to modify the path to point to your JDK. - cd /usr/lib/jvm/
- Create a symbolic link to the home of you JDK. The link name should be exactely the same as in the field "VMHANDLE" in the file. For example:
neptune jvm # ln -s /opt/jdk1.7.0_67/ oracle-jdk-1.7 - Test it with java-config -L. You should see your new JDK installed and you can select it with "java-config -S 1", then java -version.
