wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.

You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or

reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.

5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work

incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the

work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.

9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
on Your own behalf and on Your sole responsibility, not on behalf
of any other Contributor, and only if You agree to indemnify,
defend, and hold each Contributor harmless for any liability
incurred by, or claims asserted against, such Contributor by reason
of your accepting any such warranty or additional liability.

# Example Web App Using Asynchronous Servlets #

This web app demonstrates using asynchronous servlet techniques to reduce server resources.

The code for this tutorial is here: [https://github.com/GoogleCloudPlatform/java-docs-samples/managedvms/async-rest](https://github.com/GoogleCloudPlatform/java-docs-samples/managedvms/async-rest).


## Initial Setup ##

First, complete the following steps:

- [Create your project](https://developers.google.com/appengine/docs/managed-vms/) and have it enabled for Managed VMs.
- Obtain an app key for the Google Places WebService API.
- Download and install [the Beta build of the Google Cloud SDK](https://developers.google.com/cloud/sdk/#Quick_Start).
- Install the Cloud SDK `app-engine-java` component.
- Authenticate wth the gcloud SDK: gcloud auth login.
- Install [Maven](http://maven.apache.org/download.cgi) if you haven't already.



## Providing your Google Places API key ##

You will need to edit the pom.xml file and replace YOUR_PLACES_APP_KEY with the value of your key:

<places.appkey>YOUR_PLACES_APP_KEY</places.appkey>

You then have several options of how to run it:

## Running locally without the AppEngine environment ##

The application does not use any AppEngine specific services, so you can run it simply on your local machine by doing:

mvn jetty:run

Go to http://localhost:8080 to see the webapp.


## Running locally using Docker ##

The project also builds a docker image based on the jetty9 image for [Google Container Engine](https://cloud.google.com/container-engine/). The WAR file is installed in the webapps directory and the resulting image can be run locally with:

docker run --rm -it -p 8080:8080 jetty9-async-rest --exec -Dcom.google.appengine.demos.asyncrest.appKey=YOUR_PLACES_APP_KEY

Where you replace YOUR_PLACES_APP_KEY with the key you obtained in the initial setup.


## Deploying to the cloud as an AppEngine ManagedVM ##

To automatically stage and deploy the webapp to your project in the cloud do:

mvn gcloud:deploy

See here for more information on the [GCloud Maven Plugin](https://github.com/GoogleCloudPlatform/gcloud-maven-plugin).
