Road layers appearing as points in GeoServer previews - both OpenLayers and GeoExp

Question

I am wondering why my roads layer keeps appearing as points when previewed inside GeoServer - layer preview using both the OpenLayers and GeoExplorer options. The data are imported from PostGIS.

I can't figure out where the problem might be originating from as I am also new to both PostGIS and GeoServer. In PostGIS, I have added a Geometry table using:

CREATE TABLE geometries (name varchar, geom geometry);
INSERT INTO geometries VALUES
  ('Point', 'POINT(0 0)'),
  ('Linestring', 'LINESTRING(0 0, 1 1, 2 1, 2 2)'),
  ('Polygon', 'POLYGON((0 0, 1 0, 1 1, 0 1, 0 0))'),
  ('PolygonWithHole', 'POLYGON((0 0, 10 0, 10 10, 0 10, 0 0),(1 1, 1 2, 2 2, 2 1, 1 1))'),
  ('Collection', 'GEOMETRYCOLLECTION(POINT(2 0),POLYGON((0 0, 1 0, 1 1, 0 1, 0 0)))');

SELECT Populate_Geometry_Columns();

SELECT name, ST_AsText(geom) FROM geometries;

However the geometry column in my tables is named "wkb_geometry". Could this be an error? Please help!

This is a bit confusing as the inset you show is clearly not a roads layer but a test geometries table. If you are really trying to display that layer via GeoServer then you will need to read up on mixed geometry SLD files.

However, I suspect that what is actually happening is that you have some other table with lines in it to represent roads and you have applied the default point style to it. So go to the publish tab of the layer's view in GeoServer and change the style to line.
