Maven will download all the other dependencies. 13 | 14 | 15 | ## Deploying 16 | 17 | To build, run: 18 | 19 | mvn package 20 | 21 | 22 | ## Local deployment 23 | 24 | Make sure the `demo` database exists on the local MySQL server. 25 | 26 | To start the app, use the [App Engine Maven Plugin](http://code.google.com/p/appengine-maven-plugin/) that is included in this demo. Just run the command: 27 | 28 | mvn appengine:devserver 29 | 30 | 31 | ## App Engine deployment 32 | 33 | In `pom.xml` update the following properties: 34 | 35 | * `appengine.app.appId` to point to your App Engine application ID 36 | * `cloudsql.url` to point to your Cloud SQL instance by replacing `your-instance-name` with the full name of your instance (this looks either like `my_project:my_instance` for non-domain specific instances or like `my_domain:my_project:my_instance` for the domain-specific ones). 37 | 38 | Make sure the `demo` database exists on the Cloud SQL instance. 39 | 40 | To deploy the app run the following command: 41 | 42 | mvn appengine:update 43 | 44 | 45 | ## Contributing changes 46 | 47 | * See [CONTRIB.md](CONTRIB.md) 48 | 49 | 50 | ## Licensing 51 | 52 | * See [LICENSE](LICENSE) 53 | -------------------------------------------------------------------------------- /eclipse-launch-profiles/DevAppServer.launch: -------------------------------------------------------------------------------- 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 | 14 | -------------------------------------------------------------------------------- /eclipse-launch-profiles/UpdateApplication.launch: -------------------------------------------------------------------------------- 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 | 14 | -------------------------------------------------------------------------------- /nbactions.xml: -------------------------------------------------------------------------------- 1 | 2 | 3 | 4 | CUSTOM-appengine:devserver 5 | appengine:devserver 6 | 7 | appengine:devserver 8 | 9 | 10 | 11 | CUSTOM-appengine:update 12 | appengine:update 13 | 14 | appengine:update 15 | 16 | 17 | 18 | CUSTOM-appengine:rollback 19 | appengine:rollback 20 | 21 | appengine:rollback 22 | 23 | 24 | 25 | CUSTOM-appengine:update_cron 26 | appengine:update_cron 27 | 28 | appengine:update_cron 29 | 30 | 31 | 32 | CUSTOM-appengine:update_dos 33 | appengine:update_dos 34 | 35 | appengine:update_dos 36 | 37 | 38 | 39 | CUSTOM-appengine:update_indexes 40 | appengine:update_indexes 41 | 42 | appengine:update_indexes 43 | 44 | 45 | 46 | CUSTOM-appengine:update_queues 47 | appengine:update_queues 48 | 49 | appengine:update_queues 50 | 51 | 52 | 53 | -------------------------------------------------------------------------------- /pom.xml: -------------------------------------------------------------------------------- 1 | 2 | 3 | 4 | 4.0.0 5 | war 6 | 1.0 7 | 8 | com.google.appengine.demos 9 | native-mysql-hibernate-jpa 10 | 11 | 12 | your-app-id 13 | 1 14 | 1.9.48 15 | UTF-8 16 | jdbc:google:mysql://your-instance-name/demo?user=root 17 | jdbc:mysql://localhost/demo?user=root 18 | 19 | 20 | 21 | 22 | 23 | com.google.appengine 24 | appengine-api-1.0-sdk 25 | ${appengine.target.version} 26 | 27 | 28 | javax.servlet 29 | servlet-api 30 | 2.5 31 | provided 32 | 33 | 34 | jstl 35 | jstl 36 | 1.2 37 | 38 | 39 | mysql 40 | mysql-connector-java 41 | 5.1.25 42 | 43 | 44 | org.hibernate 45 | hibernate-entitymanager 46 | 4.2.0.Final 47 | 48 | 49 | 50 | 51 | com.google.appengine 52 | appengine-testing 53 | ${appengine.target.version} 54 | test 55 | 56 | 57 | com.google.appengine 58 | appengine-api-stubs 59 | ${appengine.target.version} 60 | test 61 | 62 | 63 | 64 | 65 | 66 | 67 | org.apache.maven.plugins 68 | 2.5.1 69 | maven-compiler-plugin 70 | 71 | 1.7 72 | 1.7 73 | 74 | 75 | 76 | 77 | org.apache.maven.plugins 78 | maven-war-plugin 79 | 2.3 80 | 81 | true 82 | 83 | 84 | 85 | ${basedir}/src/main/webapp/WEB-INF 86 | true 87 | WEB-INF 88 | 89 | 90 | 91 | 92 | 93 | 94 | com.google.appengine 95 | appengine-maven-plugin 96 | ${appengine.target.version} 97 | 98 | 99 | 100 | 101 | 102 | -------------------------------------------------------------------------------- /src/main/java/com/google/appengine/demos/Greeting.java: -------------------------------------------------------------------------------- 1 | /** 2 | * Copyright 2012 Google Inc.
