GeoServer Beginner's Guide

In the previous chapter, we explored the Layer list interface. All layers, publishing raster or vector data, are listed here. You can use Web Mapping Service (WMS) to publish them or the Web Feature Service (WFS) to deliver vector features. Using the Layers Preview panel you can easily check how your data looks:
As of GeoServer 2.2, the All Formats drop-down box on the Layer Preview page will still include options for WFS and WMS, even when they are not active. Due to security restrictions, when the respective services are disabled or when output formats don't apply, you'll get an error. If your layers seem to output incorrectly and display errors or are not being found, you might need to check your security settings.
