Fabric8 + E-OSGi managed persistence (Aries + Hibernate) + REST service demonstration code.

Pre-requisites

• JDK 7
• Maven 3.1.0 or newer

Build and install

mvn clean install

Provisioning

Installation and initial configuration

• Download latest build for fabric-karaf and extract it. (tested on fabric8-karaf-1.0.0.redhat-348)
• Extract it
• cd to the newly extracted folder
• Define default administrative user (login: admin, password:admin) by uncommenting the last line of etc/user.properties
• Start Fabric

bin/fusefabric

If everything goes well, you should get a Fabric shell that looks like this:

Please wait while Fabric8 is loading...

Type 'help' to get started
and 'help [cmd]' for help on a specific command.
Hit '<ctrl-d>' or 'osgi:shutdown' to shutdown this container.

Create a new Fabric via 'fabric:create'
or join an existing Fabric via 'fabric:join [someUrls]'

Start Fabric Ensemble

fabric:create --clean --wait-for-provisioning

Define our own profile

profile-create --parents example-quickstarts-rest persistence-example
profile-edit --repositories mvn:com.github.pires.example/feature-persistence/0.1-SNAPSHOT/xml/features persistence-example
profile-edit --features persistence-aries-hibernate persistence-example
profile-edit --bundles mvn:com.github.pires.example/datasource-hsqldb/0.1-SNAPSHOT persistence-example
profile-edit --bundles mvn:com.github.pires.example/dal/0.1-SNAPSHOT persistence-example
profile-edit --bundles mvn:com.github.pires.example/dal-impl/0.1-SNAPSHOT persistence-example
profile-edit --bundles mvn:com.github.pires.example/rest/0.1-SNAPSHOT persistence-example

Create and run new container with newly created profile

container-create-child --profile persistence-example root test

Testing

In Hawt.io UI, go to API tab (in the parent container), check the host and port where UserService is available and point it down. Test the REST endpoint as you wish!

REST API (JSON)

Create new user

PUT /user

Example JSON:

{
    "name":"fferreira",
    "properties":{"value":"{\"string1\":{\"mandatory\":false,\"value\":\"teste\",\"type\":\"string\"},\"num1\":{\"mandatory\":false,\"value\":123,\"type\":\"number\"}}"}
}

Count users

GET /user/count

List users

GET /user

Troubleshooting

If rest bundle is waiting on UserService, it's because dal-impl bundle is waiting on hibernate-osgi to announce its availability. Restart hibernate-osgi bundle, et voilá!

Differences from original repository

• Working with postgreSQL
• Working with a JSON object as PostgreSQL column
