You'll have to write your own plug-in to do this. It''ll have the
following steps
1. Create a FeatureSchema definition for all the columns
2. Create a java.util.Map with the key being the ID column and the
value being a Feature instance
3. Open your three data sources in turn and loop
I can create a view only if i have some right in the database.
And it is not necessary the case.
It is dangerous in verry big compagny.
At this time i have only read rigth in some Database.

Of course all feature in layer share the same shema.
An exemple :
* I have some polygone in shape file :
GEOMETRY (MULTYPOILYGONE)
ID (INTEGER)
* I have in datasource (DS1) lot of generic attributes for this polygone
like
ID (INTEGER)
POPULATION (DOUBLE)
MENAGE (DOUBLE)
* in an other dat
Layers are tied to a feature collection and all features must share the
same schema.
If you create custom Java code to load the date from each of those
sources and populate the feature collection with that data then there is
no reason why you couldn't do what you want. But there is nothing out
Hi,
It possible to have more than one datasource by layer?
1 for Geo datasource (a data source for the géometry)
1..n data source for attributes
Exemple :
* shapeFile for the geometry
* a flat CSV file for some attribute
* MysQL database for some other
* PostgreSQL database for some others.
