Currently there is no way to enable tiles validation and completion when using just Spring. I've tried using Tiles 1.x or Tiles 2.x in my app application but unless I include a struts-config.xml and reference that in my web.xml, IDEA will not enable tiles integration. We should be able to support Spring + Tiles by parsing the files location definitions in my spring-servlet.xml when using: <bean id="tilesConfigurer" class="org.springframework.web.servlet.view.tiles.TilesConfigurer"> <property name="factoryClass" value="org.apache.struts.tiles.xmlDefinition.I18nFactorySet"/> <property name="definitions"> <list> <value>/WEB-INF/tiles_config/tiles-defs.xml</value> </list> </property> </bean>
