Not really, not anymore in any case. There are various ways to add a process,
but let me show you the quickest one, which we'll add the process among
the "gs" ones.
1) Code your process using the annotations and making it implement
the marker interface GeoserverProcess. For example:
http://svn.codehaus.org/geoserver/trunk/src/extension/wps/wps-core/src/main/java/org/geoserver/wps/gs/CollectGeometries.java
2) Declare the process in the Spring context, for example:
http://svn.codehaus.org/geoserver/trunk/src/extension/wps/wps-core/src/main/java/applicationContext.xml
see in particular:
<bean id="collectGeometriesProcess"
class="org.geoserver.wps.gs.CollectGeometries"/>
You can do that in your own module, provided you declare a dependency
to wps-core.
Ah, the annotations will eventually be moved back to GeoTools and thus change
package. Also the existing processes might change name, parameters and the like.
What we have today is mostly the result of my spare time coding (though lately
we started adding processes backed by real funding, yeah!), so interfaces and
class locations are still not definitive...
I think WPS will grow strongly over then next year, but the road may
be a little bumpy
