Any update to these instructions for creating new output
formats in WFS - don't see that these classes/interfaces exist in
the trunk source code:

http://geoserver.org/display/GEOSDOC/Create+your+own+Output+Format

Thanks,
Todd

Hi Todd,

My apologies, that page is sorely out of date for GeoServer 1.6.x and trunk. I will mark it as so.

The way currently to implement a WFS output format is to extend the class org.geoserver.wfs.WFSGetFeatureOutputFormat. Something like the following:

class MyOutputFormat extends WFSGetFeatureOutputFormat {

    public MyOutputFormat() {
      super( "foo" );
      // this is the string used to identify the format in a request
      // example: '&outputFormat=foo'
    }

     public String getMimeType(Object value, Operation operation)
         throws ServiceException {
        //return the mime type of your format
     }

    protected abstract void write(
     FeatureCollectionType featureCollection,
     OutputStream output, Operation getFeature) throws IOException, ServiceException;

     //write to output stream
   }

}

After that you need to register your output format in a spring 'applicationContext.xml' file. Like this:

<beans>
   <bean id="myOutputFormat" class="MyOutputFormat"/>
</beans>

Hope that helps. If you have any problems at all or anything is unclear please feel free to ask more questions.

How are you handling/compiling the schema( xsd ). I've used XMLBeans
in the past and then referenced the compiled classes. Is there a standard
in Geoserver Dev for how the output is mapped to the schema.

Thanks
