What is This? ============== This Liftweb application will demonstrate how to manage owned One-to-Many relation on Google App Engine for Java through the JDO2 interface. The code has been based on Derek Chen-Becker's JPADemo. How to Try ========== Before the compilation, a step is needed to be done. 1. Set your application name on GAE/J to 'src/main/webapp/WEB-INF/appengine-web.xml' file. Now, you are ready to run or upload this liftweb application to GAE/J. $ mvn gae:deploy or $ mvn gae:run See http://www.kindleit.net/maven_gae_plugin/plugin-info.html for more info. Notes ===== * Entity models are defined in com.jcraft.lift.model package. * This program defines two models; Author and Book, and they are detachable. Refer to those source code. * Author includes many instances of Book. * DetachOnClose and DatachOnCommit has been enabled by the default. Refer to 'src/main/webapp/WEB-INF/classes/META-INF/jdconfig.xml' * Without definitions for indexes, objects in One-to-Many relation must not be persisted. Refer to 'src/main/webapp/WEB-INF/datastore-indexes.xml' * The package org.scala_libs.jdo is the scala wrapper for JDO2 APIs. TODO ==== * org.scala_libs.jdo package should be independently released and provided as scalajdo.
