// joynrConfig.setProperty(MessagingPropertyKeys.BOUNCE_PROXY_URL,
// "http://localhost:8080/bounceproxy/");
// joynrConfig.setProperty(MessagingPropertyKeys.DISCOVERYDIRECTORYURL,
// "http://localhost:8080/discovery/channels/discoverydirectory_channelid/");
// Each joynr instance has a local domain. It identifies the execution
// device/platform, e.g. the
// vehicle. Normally, providers on that instance are registered for the
// local domain.

// 2) Or set them in the static persistence file (default:
// joynr.properties in working dir) at
// runtime. If not available in the working dir, it will be created
// during the first launch
// of the application. Copy the following lines to the custom
// persistence file to set a
// certain joynr server instance.
// NOTE: This application uses a custom static persistence file
// provider-joynr.properties.
// Copy the following lines to the custom persistence file to set a
// certain joynr server
// instance.
// joynr.messaging.bounceproxyurl=http://localhost:8080/bounceproxy/
// joynr.messaging.discoverydirectoryurl=http://localhost:8080/discovery/channels/discoverydirectory_channelid/
// 3) Or set them in Java System properties.
// -Djoynr.messaging.bounceProxyUrl=http://localhost:8080/bounceproxy/
// -Djoynr.messaging.capabilitiesDirectoryUrl=http://localhost:8080/discovery/channels/discoverydirectory_channelid/

// Programmatically set configuration properties override properties set
// in the static persistence file.

// them on the JoynApplicationModule.
