Dan Haywood resolved ISIS-322.
------------------------------
Resolution: Fixed
> Allow JDO objectstore to run on the Google App Engine
> -----------------------------------------------------
>
> Key: ISIS-322
> URL: https://issues.apache.org/jira/browse/ISIS-322
> Project: Isis
> Issue Type: New Feature
> Components: Objectstore: JDO
> Affects Versions: objectstore-jdo-1.0.0
> Reporter: Dan Haywood
> Assignee: Dan Haywood
> Fix For: objectstore-jdo-1.2.0
>
> Attachments: DataNucleusApplicationComponents.patch
>
>
> Following info provided by Maurizio Taverna...
> We have (with some provisos) successfully deployed a version of the quickstart_wicket_restful_jdo on GAE.
> Below the information collected :
> 1. DataNucleusApplicationComponents.java
> 61:persistenceManagerFactory = JDOHelper.getPersistenceManagerFactory(props);
> replaced with :
> 61:persistenceManagerFactory = JDOHelper.getPersistenceManagerFactory("transactions-optional");
> See official Google documentation :
> https://developers.google.com/appengine/docs/java/datastore/jdo/overview-dn2#Getting_a_PersistenceManager_Instance
> 66:createSchema(props, classesToBePersisted);
> replace with :
> // 66:createSchema(props, classesToBePersisted);
> This feature is for RDBMS, it raise exception using DN Google implementation.
> 2. PersistenceSession.java
> 894:if (adapter.getVersion() == null) {
> 895: throw new ObjectPersistenceException("Object to be ... " + adapter);
> 896:}
> replaced with:
> 894://if (adapter.getVersion() == null) {
> 895:// throw new ObjectPersistenceException("Object to be ... " + adapter);
> 896://}
> We could not understand why the version is null, during the fixture installation ( removeAllToDosForCurrentUser ).
> 3. jdoconfig.xml
> The Google App Engine keep the Jdo configuration in /WEB-INF/classes/META-INF/jdoconfig.xml.
> We changed :
> <property name="datanucleus.appengine.autoCreateDatastoreTxns" value="false"/>
> This is a workaround, more information available here:
> https://developers.google.com/appengine/docs/java/datastore/jdo/overview-dn2#Disabling_Transactions_and_Porting_Existing_JDO_Apps
> With the changes above, the quickstart_wicket_restful_jdo is possible install the fixtures and list the items,
> but there are still errors accessing to an item.
> At https://docs.google.com/file/d/0B-Ekm92XLvTAcGxHNTJyRDA3bkk/edit?usp=sharing please find the zip of the project, including the ant build script , a live version is available here: http://isis-gae.appspot.com/.
> In order to run the example you need to install the GAE SDK and point the appengine.sdk property
> to the GAE SDK installation path.
> In addition please check in {gae.sdk}lib/tools/orm contains the datanucleos 3.1.1 jars. If not remove all the jar files (in default installation I found datanucleus 1.5 jars) and replace with jars available in {gae.sdk}/lib/opt/user/datanucleus/v2.
