I’ve got an SRS-related question: how can a GeoServer datastore automatically obtain the SRS of a data set when creating a new Feature Type? From my point of view, the two possibilities are:
1.) I read the SRS directly from the data structure (the SRS is contained in the XML-based data structure).
2.) I hardcode the SRS somewhere in the datastore source (not my preference)
In other words, my question is: how can GeoServer automatically populate the “SRS” field in the “FeatureType Editor” dialog; i.e. which variable/parameter in the code does it read to do this?
Thanks for your advices already in advance,
Bernd.
I believe it uses the geotools DataStore to query the database schema
directly to obtain the SRS. So basically the SRS that shows up on the new
FeatureType screen is the SRS in which data in ur database is stored

Yes, it is dependent on the datastore being used and if the dataset in question properly declares its SRS information. If GeoServer can figure it out it will populate the SRS field, so if it is not it means it is having a problem finding the SRS of your dataset.
What is the backend datasource you are using? If it is a Shapefile does your shapefile have a .prj with it. And that does that .prj properly declare the EPSG code? Many do not.
For postgis, does your table have a geometry columns entry?
Let us know what backend you are using and we can probably better help.
