Editing GeoServer (section)

== Architecture ==
GeoServer uses the [[Spring Framework]], providing a request dispatch architecture for modules implementing OGC services. The web administration application uses wicket, allowing extensions to contribute additional configuration screens. The application provides a REST API implemented using the [[Spring Framework#Model–view–controller framework|spring-mvc-framework]].

GeoServer is a web application, supporting any common [[Java Servlet#Servlet containers|servlet container]] (a standalone distribution is available with the [[Jetty (web server)]] as an embedded server). [[GeoWebCache]], a Java-based caching component similar to [[TileCache]], is bundled with GeoServer, but available separately.<ref>{{cite web |url=http://geowebcache.org/trac |title=GeoWebCache |url-status=usurped |archiveurl=https://web.archive.org/web/20100405124130/http://geowebcache.org/trac |archivedate=2010-04-05 }}</ref> Similarly, GeoServer packages GeoTools as a Java library, but it is also available separately.<ref>{{cite web|url=http://geotools.org/|title=GeoTools}}</ref>

GeoServer is a longstanding application and has undergone several architectural changes. GeoServer 1.0 was built around the STRUTS framework, with the migration to Spring and Wicket taking place for GeoServer 2.0. Early versions of the REST API used restlet before migration to [[Spring Framework#Model–view–controller framework|spring-mvc-framework]].
