Andrea,
I had a look in the code and by default it will try to enable joining if:
mappedSource instanceof JDBCFeatureSource || mappedSource instanceof
JDBCFeatureStore
Furthermore, the exception will only be thrown if joining is
*explicitly* enabled and the source does not support it. The default
behaviour is to quietly turn joining on for the above two sources and
off otherwise.
Kind regards,
Ben.

Hi Ben,
wondering, can the joining support logic in app-schema check the store
query capabilities (if it's using GeoTools joins), or check if
the store is indeed a JDBCDataStore?
Cheers
Andrea

Adrien,
app-schema is incorrectly guessing that your database is a JDBC database
that supports SQL JOIN and is trying to use this functionality for improved
performance. As this will not work for SOLR, you should turn joining off by
setting -Dapp-schema.joining=false at the JVM command line or in
WEB-INF/classes/app-schema.properties . See also:

Kind regards,
Ben.

Ok, so from solr plugin documentation, sourceType/layer seems to be the
collection in solR.
configuring app-schema like this, the exception disappear. We could
suppose
it's a success here!
but, one exception remains, request a GetFeature on this feature setup
with
app-schema and solR datastore raise this exception :

any idea?
