Introduction
The Tynamo Tapestry-JDO module allows you to work with a JDO2 (www.oracle.com/technetwork/java/index-jsp-135919.html) backed persistence layer, similarly to the way you would work w/ a JPA or Hibernate based persistence layer. JDO's main appeal is in its extensive support for ORM into relational databases (e.g. MySQL) as well as non-relational data stores (e.g. MongoDB through Datanucleus MongoDB Support, Google AppEngine JDO API, etc)
Configuration
In order to have a working configuration, the following are required:
- A dependency on org.tynamo:tapestry-jdo
- A JDO implementation (we use datanucleus in our examples, but others such as Apache JDO should work as well). The implementations typically have some way of integrating the JDO Enhancement process into the build; although not absolutely necessary (e.g. you could probably do that manually after you run your build and before packaging your app), it would probably be a good idea
- A properly configured jdoconfig.xml
Add dependency on Tapestry-JDO
Just adding this dependency will bring transitive dependency on jdo2.
Maven dependency for tapestry-jdo
Add your JDO implementation
Add your own dependencies for your JDO implementation if you're using something different:
JDO Implementation Dependencies
Configure build to instrument your JDO classes:
JDO Enhancer Configuration in Maven
Add your persistence store driver :
JDBC Driver Dependency
Setup your JDO configuration (jdoconfig.xml):
jdoconfig.xml
Contribute the PersistenceManagerFactory name to your AppModule:
Contribute Persistence Manager Factory name
Usage
Inject PersistenceManager into your pages:
Injecting JDO Persistence Manager
Auto-Commit in your pages
@CommitAfter in pages
Configure service transactional behavior
Service transactions
Use JDO object as page contex
Classes that use a simple primary key (e.g. Long, String, etc) can be used as an acitvation/passivation context directly
Activate/Passivate
