Hi,
The last days I spend some time on implementing a nice new feature in Texo: the JSONTexoResource.

With this EMF resource implementation it is possible to run your RCP in a standards compliant 3-tier architecture. This
new EMF resource allows you to retrieve/persist your EMF EObjects remotely from a JPA/JSON web server which stores its
data in a relational db. It uses JSON over HTTP as the communication protocol.

Other features:
- automatic remote EMF proxy resolving
- support for JPQL queries to load objects, cross referencing queries, refreshing objects on the client

For more information see these links here:

Martin,

That sounds really useful! My students often ask for JSON support,
particularly when communicating with web services and mobile clients.

Nice to hear Hallvard, by getting 2 plugins (org.eclipse.emf.texo/org.eclipse.emf.texo.json) you can do EMF <--> JSON
conversions and include the JSONTexoResource in a RCP.

Your students can connect their mobile web clients to the Texo generated server side quite easily:
http://martintaal.wordpress.com/2012/04/05/emf-texo-json-rest-web-service-support-connecting-your-client-to-an-emf-supporting-web-server/

The JSON server side support has quite some features especially for higher volume datasets.
