Need to update application schema, Please help. [message #74904]

Hi,

I am using XML Schema, EMF, Teneo and hibernate for managing the
application persistent layer.

I am new to these technologies.
Currently the code for the persistent layer is already generated from
the XML Schema (XML Schema -> Ecore -> Model) and Teneo is used for
integrating with Hibernate.

Now I need to modify the current schema, need to add some new fields in
the existing tables and need to add some new tables.

I can update these changes in the XML Schema (XSD file). But I don't
know how to generate the corresponding Ecore file from the updated xsd
file, or is there any other way of doing this.

Can someone please help me.

Regards,
Prashant

Hi,

You need to right click the .genmodel and hit "Reload...".

Cheers,
Marcelo

Hi Prashant,
If you right-click on the genmodel and choose reload then you can reload the xsd into the genmodel.
After reloading, regenerate the java classes (right-click on the epackage in the genmodel). Teneo
picks up the new ecore model automatically and will create a new mapping, hibernate will then update
the database (depends on the hbm2ddl setting). Note that hibernate in update mode add columns and
tables but does not add indexes.
