| Since Jetty can be incredibly simple to embed, many people choose to create a small | |
| <code class="code">main</code> | |
| method which they can launch directly within Eclipse in order to more easily debug their entire application. | |
| The best place to get started on this approach is to look through | |
| <a class="xref" href="embedding-jetty.html" title="Embedding Jetty">Embedding Jetty</a> | |
| and the | |
| <a class="xref" href="embedded-examples.html" title="Embedded Examples">Embedded Examples</a> | |
| sections. | |
| </p><p> | |
| Once you have a main method defined in order to launch your application, right-click on the source file and | |
| select<span class="bold"><strong>Debug As -> Java Application</strong></span>. In your | |
| <span class="bold"><strong>Console</strong></span> | |
| tab within Eclipse you should see your application startup and once it has completed startup you should be | |
| able to configure breakpoints and hit the Jetty instance as normal via your web browser. | |

| You can easily configure logging through a | |
| <code class="filename">jetty-logging.properties</code> | |
| file. If this file is on your classpath then Jetty will use it for configuring logging, we use this | |
| approach extensively throughout Jetty development and it makes life ever so much easier. You can see | |
| this in action in the | |
