| minimal footprint by selecting the minimal set of jars. Typically it is |
| best to use something like Maven to manage jars, however this tutorial |
| uses an aggregate Jar that contains all of the Jetty classes in one Jar. |
| You can manually download the aggregate jetty-all Jar and the servlet api |
| Jar using <a class="link" href="http://www.gnu.org/software/wget/" target="_top">wget</a> or |
| similar command (for example, <a class="link" href="http://curl.haxx.se/" target="_top">curl |
| </a>) or a browser. Use wget as follows:</p><div class="screenexample"><pre class="screen">mkdir Demo |
| cd Demo |
| wget -O jetty-all.jar -U none http://repo1.maven.org/maven2/org/eclipse/jetty/aggregate/jetty-all/9.0.0-RC1/jetty-all-9.0.0-RC1.jar |
| wget -O servlet-api.jar -U none http://repo1.maven.org/maven2/org/eclipse/jetty/orbit/javax.servlet/3.0.0.v201112011016/javax.servlet-3.0.0.v201112011016.jar</pre></div></div><div class="section"><div class="titlepage"><div><div><h3 class="title"><a name="writing-helloworld-example"></a>Writing a HelloWorld Example</h3></div></div></div><p>The <a class="link" href="">Embedding Jetty</a> section |
| contains many examples of writing against the Jetty API. This tutorial |
| uses a simple HelloWorld handler with a main method to run the server. You |
| can either <a class="link" href="http://git.eclipse.org/c/jetty/org.eclipse.jetty.project.git/plain/examples/embedded/src/main/java/HelloWorld.java" target="_top">download</a> |
