<p><i>From Allen Hopkins' notes at <a href="http://www.gigascale.org/infrax/faq/138.html">How to install java</a></i>

<p>The "Java 2 Platform Enterprise Edition" is required to support
servlets and JavaServer Pages (JSP) on our website.

<p>Go to <a href="http://www.oracle.com/technetwork/java/javaee/downloads/index.html">http://www.oracle.com/technetwork/java/javaee/downloads/index.html</a> and download the most recent version of GlassFish.</p>

<p>As of January, 2016, this was <code>Oracle GlassFish Server 3.1.2.2</code>.

<p>Download the "Linux/Unix/Mac Zip", which was <code>ogs-3.1.2.2.zip</code>.</p>

<p>Unzip it in <code>/usr/local</code>

<p>Stop the everything, make a link and restart</p>

Download the J2EE SDK version 1.3.1 (or the latest) from 
<a href="http://www.oracle.com/technetwork/java/index.html">http://www.oracle.com/technetwork/java/index.html</a> and install it,
per their instructions.  
<br/>Oct, 2012: For linux, I downloaded 
Java EE 6 SDK with JDK 7 U7 &gt; <code> java_ee_sdk-6u4-jdk7-linux-x64.sh</code>
<br/>I had to install the Oracle version of Java and do
<pre>
export JAVA_HOME=/usr/lib/jvm/jdk1.7.0_07
</pre>

If the installation ends up in /usr with a non-version-specific name,
rename it to include its version number, and make "/usr/j2ee" be a
symbolic link pointing to it.
<h3>Java EE 5 SDK Update 5 Notes</h3>
<p>12/08: I downloaded "Java EE 5 SDK Update 5 (with JDK 6u7) for Solaris SPARC, English", which was <code>java_ee_sdk-5_05-solaris-sparc.bin</code>.
To install, I ran:
<pre>
/export/home1/root/tools/downloads/java_ee_sdk-5_05-solar
is-sparc.bin -console
</pre> 
<p>Make the following changes:
<dl>
<dt><code>Installation Directory</code>
<dd>Use <code>/usr/j2ee-5_05</code>.
We will make a link later
<dt><code>User Name</code> and <code>Password</code>
<dd>Use the <code>admin</code> User Name and the
same passwd as <code>www</code>
<dd>I chose to save the password
<dt>Port names
<dd>I stuck with the defaults:
<pre>
Admin Port [4848] {"<" goes back, "!" exits}: 
   HTTP Port [8080] {"<" goes back, "!" exits}: 8080
   HTTPS Port [8181] {"<" goes back, "!" exits}: 
</pre>
<dd>I chose to enable update center
<dd>I chose not to update a previous version
</dl>

Fix up links:
<pre>
cd /usr
rm j2ee
ln -s j2ee-5_05 j2ee
cd /usr/jdk
rm latest
ln -s /usr/j2ee/jdk latest
</pre>
