+# Repro project for SPR-14971
+
+## Deploying
+
+It is possible to deploy your application directly from the command-line
+using maven. You can use either [cargo](http://cargo.codehaus.org/) or
+the [jetty plugin](http://www.eclipse.org/jetty/documentation/current/jetty-maven-plugin.html)
+to run on a wide range of containers.
+
+### Cargo
+
+By default Cargo is configured to start `Tomcat7` and can be invoked by
+running `mvn package cargo:run`. Cargo can also run a [wide range of other
+containers](http://cargo.codehaus.org/Containers) and you can easily add
+yours by editing the `pom.xml`. For instance, a `tomcat8` profile
+has been added and can be invoked via `mvn package cargo:run -Ptomcat8`.
+
+You can remote debug the application, in your IDE, by using the following command:
+ `mvn package cargo:run -Ptomcat8 -Pdebug`. Note that you can customize the debug
+ port used with the `cargo.jvm.debug.port` maven property.
+
+### Jetty
+
+To deploy your application to jetty9, simply invoke `mvn jetty:run`. It
+is possible to tune the exact jetty9 version you want to use by specifying
+the version of the command line, e.g. `mvn jetty:run -Djetty.version=9.0.6.v20130930`
+
+To run a different version of jetty, please fallback to cargo as the
+coordinates of the maven plugin have changed. A sample `jetty8` profile is
+created for reference and can be tuned to suit your needs. To deploy your
+sample application to jetty8 run `mvn cargo:run -Pjetty8`
+
+## Logging
+
+This project contains a `log4j.properties` file in `src/main/resources` that you
+may wish to configure to emit more detailed logging.  The root logger is set to
+`INFO` and a custom `org.springframework.web` logger is set to `DEBUG`.
