To add WFS feature types from named tables:
From above the feature types tree, click the Add Feature Types button .
From the dialog, select one or more named tables to add and click
The details page for the first named table you selected appears.
Note: By default,
the WFS feature type is created under the namespace you were located when you
added the feature type. You can drag and drop the feature type to move it under
a different namespace if needed.
Optional From the GetFeature Preview tab, select at least one
column to see a preview of the GetFeature request. The purpose of the preview
tab is to test the feature type using a DescribeFeatureType to retrieve the
columns, then performing a GetFeature request to show features. You may also set
Maximum Features to limit your results to a subset; the value in this field must
be at least 1 and cannot exceed the Maximum Features value on the WFS Settings
page. If left blank then there is no limit in number of features returned;
however, if you exceed the Maximum Features on the Settings page then you will
receive an error.
