Hi All,
Here's my Use Case:

Intro:
We are using GXT (extjs with GWT) as a front-end. GXT UI widgets (grids,trees) naturally bind to any POJO that implements DataModel ( http://www.extjs.com/deploy/gxtdocs/com/extjs/gxt/ui/client/ data/BaseModelData.html).

We also have invested in using EMFT stack (Ecore models, Teneo, etc.) to build our models.

We would like to (at runtime) marshal/unmarshal OR serialize/deserialize between Ecore model instances and DataModel POJOs as described above.

Q1) Which tooling (approach) would support this use case?
Q2) We thought of creating a custom Resource that can mapping between these two models - is this the right approach?
Q3) We also thought of using Ecore -> XML -> XML/java binding to POJOS. Is this a wrong approach?
Q4) What about leveraging built in Ecore -> XML feature and making all data available via web services (idea similar to Servus - is this alive yet). And then have a front-end like GXT talk via web service interface.

I hope my questions make sense.

Mdu,

Please avoid cross posting the same question to multiple newsgroups.
