65The way Java is handled on Gentoo has recently seen many changes and
66improvements. This has only happened very recently, and as a result, all the
67packages related to it are marked with testing keywords, ie ~x86. This
68document assumes you are using the new system.

78If you are using the stable tree, i.e. x86, ppc, or amd64 as opposed to ~x86,
79~ppc, or ~amd64, you will need to add some entries to your

530<p>
531If you are running a mixed 64-bit and 32-bit multilib system (for example, on
532AMD64), you can use 64-bit and 32-bit Java plugins. Unless you have a pressing
533need to run 32-bit Java applications, we recommend using native 64-bit plugins
534on 64-bit web browsers.
535</p>
536
537<p>
538There are several native 64-bit browser plugins available. The default JDK/JRE
539pair, <c>sun-jdk</c> and <c>sun-jre-bin</c>, both include browser plugins. Just
540emerge one of them with the <c>nsplugin</c> USE flag enabled.
541</p>
542
543<pre caption="Installing a 64-bit plugin">
544# <i>echo "dev-java/sun-jre-bin nsplugin" >> /etc/portage/package.use</i>
545# <i>emerge sun-jre-bin</i>
546</pre>
547
548<p>
549To use a 32-bit plugin on a 32-bit browser, you will need to emerge
550<c>emul-linux-x86-java</c> with the <c>nsplugin</c> USE flag enabled.

555# <i>emerge emul-linux-x86-java</i>
556</pre>
557
558<p>
559Next, check which plugins are available:
