Hi, I am in the process of upgrading from Tiles 1 to Tiles 2.2.2 combined with Struts 1.1.
I have the following configuration in struts-config.xml <controller processorClass="org.apache.struts.tiles.TilesRequestProcessor"/> <plug-in className="org.apache.struts.tiles.TilesPlugin" > <set-property property="definitions-config" value="/WEB-INF/tiles.xml"/> <set-property property="moduleAware" value="true" /> <set-property property="definitions-parser-validate" value="true" /> </plug-in> Below is the dtd configured in tiles.xml <!DOCTYPE tiles-definitions PUBLIC "-//Apache Software Foundation//DTD Tiles Configuration 2.0//EN" "http://tiles.apache.org/dtds/tiles-config_2_0.dtd"> I have the tiles2.2.2 related jars(tiles-jsp, tiles-servlet, tiles-template, tiles-api, tiles-core) in my classpath and I use maven to import jars in my project When I start tomcat and display my page, I get the following error, Mar 11, 2013 12:54:52 PM org.apache.catalina.core.ApplicationDispatcher invoke SEVERE: Servlet.service() for servlet jsp threw exception org.apache.tiles.template.NoSuchAttributeException: Attribute 'topmenu' not found. at org.apache.tiles.template.DefaultAttributeResolver.computeAttribute(DefaultAttributeResolver.java:49) at org.apache.tiles.template.InsertAttributeModel.resolveAttribute(InsertAttributeModel.java:187) at org.apache.tiles.template.InsertAttributeModel.start(InsertAttributeModel.java:107) It is not able to find any of the attributes in tiles.xml Any thoughts?
