You can install the free icedtea jdk or Oracle's version.
Jdk is {{package|dev-java/oracle-jre-bin}} & additional software for java development.
Therefore we have a virtual package called ''virtual/jdk''. By default it will install the Oracle version.  Jdk is {{package|dev-java/oracle-jre-bin}} & additional software for development.


== Installation ==
=== Installation ===
{{console|body=
{{console|body=
###i## emerge -a virtual/jdk
###i## emerge dev-java/oracle-jdk-bin
}}
}}


If you receive a message similar to the following, you will have to accept the Oracle java license to emerge the {{c|oracle-jdk-bin}}:
=== Configuration ===
==== JVM ====
list java virtual machines:
{{console|body=
{{console|body=
###i## emerge virtual/jdk
###i## eselect java-vm list
Calculating dependencies... done!
}}

[##g##ebuild  N    ##!g##] ##g##app-admin/eselect-java-0.1.0 ##!g##
[##g##ebuild  N    ##!g##] ##g##dev-java/java-config-2.2.0-r1000  ##!g## PYTHON_ABIS="##r##2.7 3.3##!r## ##bl##-2.6 -3.1 -3.2 -3.4 (-3.5)##!bl##"
[##g##ebuild  N    ##!g##] ##g##dev-java/oracle-jdk-bin-1.8.0.11 ##!g## USE="##r##X alsa fontconfig nsplugin##!r## ##bl##(-aqua) -derby -doc -examples -jce -pax_kernel (-selinux) -source##!bl##"


The following ##r##license changes##!r## are necessary to proceed:
set java virual machine os oracle jdk:
(see "package.license" in the portage(5) man page for more details)
{{console|body=
# required by oracle-jdk-bin (argument)
###i## eselect java-vm set system oracle-jdk-bin-1.7
##g##>=dev-java/oracle-jdk-bin-1.8.0.11 Oracle-BCLA-JavaS##!g##
}}
}}


To accept the required license, create the directory {{c|/etc/portage/package.license}} if it does not already exist.
==== Browser Plugin ====
list java browser plugins:
{{console|body=
{{console|body=
###i## mkdir /etc/portage/package.license
###i## eselect java-nsplugin list
}}
}}


After we create this directory, portage will read files that we create inside of it to see that we have accepted licenses required to install certain packages. To accept the license for {{c|oracle-jdk-bin}}, create a file called something like {{c|/etc/portage/package.license/oracle-jdk-bin}} and add the line {{c|dev-java/oracle-jdk-bin Oracle-BCLA-JavaS}} to it:
set java browser plugin to oracle jdk:
 
===== 32bit =====
{{console|body=
{{console|body=
###i## tee /etc/portage/package.license/oracle-jdk-bin <<< "dev-java/oracle-jdk-bin Oracle-BCLA-JavaS"
###i## eselect java-nsplugin set 32bit oracle-jdk-bin-1.7
}}
}}


Now you can emerge {{c|oracle-jdk-bin}}
===== 64bit =====
{{console|body=
{{console|body=
###i## emerge virtual/jdk
###i## eselect java-nsplugin set 64bit oracle-jdk-bin-1.7
}}
}}


After the installation finishes, you may want to check and see if you can use the jdk. You can do so by issuing the following command:

After the installation finishes, you may want to check and see if you can use the jre components of jdk. You can do so by issuing the following command:

Jdk is dev-java/oracle-jre-bin & additional software for java development.

Installation

root # emerge dev-java/oracle-jdk-bin

Configuration

JVM

list java virtual machines: 

root # eselect java-vm list

set java virual machine os oracle jdk: 

root # eselect java-vm set system oracle-jdk-bin-1.7

Browser Plugin

list java browser plugins: 

root # eselect java-nsplugin list

set java browser plugin to oracle jdk:

32bit
root # eselect java-nsplugin set 32bit oracle-jdk-bin-1.7
64bit
root # eselect java-nsplugin set 64bit oracle-jdk-bin-1.7

Runtime

After the installation finishes, you may want to check and see if you can use the jre components of jdk. You can do so by issuing the following command: 

user $ java -jar file.jar
