+=====================
+Use Pygments in Java
+=====================
+
+Thanks to `Jython <http://www.jython.org>`_ it is possible to use Pygments in
+Java.
+
+This page is a simple tutorial to get an idea of how this works. You can
+then look at the `Jython documentation <http://www.jython.org/docs/>`_ for more
+advanced uses.
+
+Since version 1.5, Pygments is deployed on `Maven Central
+<http://repo1.maven.org/maven2/org/pygments/pygments/>`_ as a JAR, as is Jython
+which makes it a lot easier to create a Java project.
+
+Here is an example of a `Maven <http://www.maven.org>`_ ``pom.xml`` file for a
+project running Pygments:
+
+.. sourcecode:: xml
+
+    <?xml version="1.0" encoding="UTF-8"?>
+
+    <project xmlns="http://maven.apache.org/POM/4.0.0"
+             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
+             xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
+                                 http://maven.apache.org/maven-v4_0_0.xsd">
+      <modelVersion>4.0.0</modelVersion>
+      <groupId>example</groupId>
+      <artifactId>example</artifactId>
+      <version>1.0-SNAPSHOT</version>
+      <dependencies>
+        <dependency>
+          <groupId>org.python</groupId>
+          <artifactId>jython-standalone</artifactId>
+          <version>2.5.3</version>
+        </dependency>
+        <dependency>
+          <groupId>org.pygments</groupId>
+          <artifactId>pygments</artifactId>
+          <version>1.5</version>
+          <scope>runtime</scope>
+        </dependency>
+      </dependencies>
+    </project>
+
+The following Java example:
+
+.. sourcecode:: java
+
+    PythonInterpreter interpreter = new PythonInterpreter();
+
+    // Set a variable with the content you want to work with
+    interpreter.set("code", code);
+
+    // Simple use Pygments as you would in Python
+    interpreter.exec("from pygments import highlight\n"
+        + "from pygments.lexers import PythonLexer\n"
+        + "from pygments.formatters import HtmlFormatter\n"
+        + "\nresult = highlight(code, PythonLexer(), HtmlFormatter())");
+
+    // Get the result that has been set in a variable
+    System.out.println(interpreter.get("result", String.class));
+
+will print something like:
+
+.. sourcecode:: html
+
+    <div class="highlight">
+    <pre><span class="k">print</span> <span class="s">&quot;Hello World&quot;</span></pre>
+    </div>
