109The default is Blackdown for both the JRE and the JDK, as it is freely ("free
110as in beer") available without any registration fuss.

114Both the Sun and the IBM are generally faster, but getting them is a bit more
115hassle, as you are required to read and accept their license before downloading
116(IBM additionally requires you to register).

254will then be used when running the <path>/usr/bin/{java,javac,..}</path>

476<p>
477You can install a Java plugin for your web browser by emerging a Java VM with
478the <c>nsplugin</c> USE flag set.
479</p>
480
481<note>
482<c>nsplugin</c> is not available for all architectures. Check for available
483plugins on your arch before trying to install a VM by running <c>emerge -pv
484&lt;java-vm&gt;</c>.
485</note>
486
487<p>
488Portage will allow you to install multiple versions of Java plugins, though
489only one will be used by your browser. You can check the list of available
490plugins by running:
491</p>
492
493<pre caption="Viewing available plugins">
494# <i>eselect java-nsplugin list</i>
495 [1] sun-jre-bin-1.6
496 [2] icedtea6-bin
497</pre>
498
499<p>
500In this example, <c>sun-jre-bin</c> is selected for the browser plugin.
501</p>
502
503<pre caption="Selecting a plugin">
504# <i>eselect java-nsplugin set sun-jre-bin-1.6</i>
505</pre>
506
507<p>
508Verify that the correct plugin was selected:

518Java.com also provides a link to <uri
519link="http://java.com/en/download/installed.jsp">verify your installed
520plugin</uri>. Additionally, if you are using a Mozilla-based browser, you can
521verify your Java plugin by typing <c>about:plugins</c> into the address bar.

527<title>Plugins on multilib systems</title>
528<body>
529
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.
551</p>
552
553<pre caption="Installing a 32-bit plugin">
554# <i>echo "app-emulation/emul-linux-x86-java nsplugin" >> /etc/portage/package.use</i>
555# <i>emerge emul-linux-x86-java</i>
556</pre>
557
558<p>
559Next, check which plugins are available:
560</p>
561
562<pre caption="Viewing available plugins">
563# <i>eselect java-nsplugin list</i>
564Available 32-bit Java browser plugins
565 [1] emul-linux-x86-java-1.5

567Available 64-bit Java browser plugins
568 [1] icedtea6-bin
569 [2] sun-jre-bin-1.6
570</pre>
571
572<p>
573Now select the right plugin for your browsers:
574</p>
575
576<pre caption="Selecting plugins">
