With this Plugin for [http://www.jspwiki.org JSPWiki] you can enter mathematical formulas in Latex syntax directly in the Wiki and display them as Gifs in a similar way like it is possible with the famous [http://www.wikipedia.org Wikipedia]. Everything happens in Java - you do not need Latex or other non-java binaries.

The visualization of the formulas is most of the work. This is done by [http://www.atp.rub.de/VCLab/software/HotEqn/HotEqn.html HotEnq], a Java Component of the Ruhr University Bochum, specialist area automatic control engineering and process computer science. Thank you at Professor Dr. Dr.-Ing. Christian Schmid for friendly permission.

For the generation of the GIF images the ACME.jar of the [http://www.acme.com ACME Laboratories] is used (Freeware).

====Example====

[[Math Aligncenter Fontsize162sum I1n A I Int Ab F Ixg Ix Dx|{Math align='center' fontsize='16'

2\sum_{i=1}^n a_i \;\int_a^b f_i(x)g_i(x)\,dx
}]]

is created by the following syntax:

<pre><code>
[{Math align='center' fontsize='16'

2\sum_{i=1}^n a_i \;\int_a^b f_i(x)g_i(x)\,dx
}]
</code></pre>

====Installation====

1. The following jars must be copied to {JSPWiki}/WEB-INF/lib:

* [[SBaltes Plugins SBaltes Plugins Jar|SBaltesPlugins.jar]]
* [[Math Plugin Hot Eqn Jar|HotEqn.jar]]
* [[Math Plugin Acme Jar|Acme.jar]]

2. The following must be added to {JSPWiki}/WEB-INF/web.xml:

<pre><code>
<servlet>
<servlet-name>DownloadJobServlet</servlet-name>
<servlet-class>
com.ecyrd.jspwiki.plugin.DownloadJobServlet
</servlet-class>
</servlet>

<servlet-mapping>
<servlet-name>DownloadJobServlet</servlet-name>
<url-pattern>/downloadJob</url-pattern>
</servlet-mapping>
</code></pre>
<br />

3. Under Linux/Unix you may enable the awt headless mode (see [http://forum.java.sun.com/thread.jsp?forum=20&thread=132877 Headless-Mode in JDK 1.4]). You can do it in two ways:
* Edit Wiki.jsp and append <tt>System.setProperty("java.awt.headless", "true");</tt> in the init-method
* edit the catalina.sh and append <tt>CATALINA_OPTS='-Djava.awt.headless=true'</tt> at the head of the file

The source code is part of the SBaltesPlugins.jar.
