Here you will find the steps to create reusable Tiles pieces and complete pages. * Create a template Let's take the <> page structure: [../../images/tiled_page.png] The "classic layout", a typical structure of a web page. Create a JSP page that acts as this layout and place it under <<>> file. ------------------------------- <%@ taglib uri="http://tiles.apache.org/tags-tiles" prefix="tiles" %> <tiles:getAsString name="title"/>

------------------------------- This template has five attributes: <<>> (of <<<string>>> type), <<<header>>>, <<<menu>>>, <<<body>>> and <<<footer>>>. * Create the composing pages In this phase, you have to create four JSP pages, that will take place of <<<header>>>, <<<menu>>>, <<<body>>> and <<<footer>>> attributes in the previously created template. You can put everything you want in this pages, they are just a test. * Create a definition Supposing that you configured Tiles, in <<<web.xml>>>, to startup using the <<<TilesServlet>>>, you need to specify what will be the files containing the Tiles definitions to load: ------------------------------------ <servlet> <servlet-name>tiles</servlet-name> <servlet-class>org.apache.tiles.servlet.startup.TilesServlet</servlet-class> <init-param> <param-name>org.apache.tiles.impl.BasicTilesContainer.DEFINITIONS_CONFIG</param-name> <param-value>/WEB-INF/tiles-defs.xml</param-value> </init-param> <load-on-startup>2</load-on-startup> </servlet> ------------------------------------ Create the <<</WEB-INF/tiles-defs.xml>>> file: ------------------------------------ <?xml version="1.0" encoding="ISO-8859-1" ?> <!DOCTYPE tiles-definitions PUBLIC "-//Apache Software Foundation//DTD Tiles Configuration 2.1//EN" "http://tiles.apache.org/dtds/tiles-config_2_1.dtd"> <tiles-definitions> <definition name="myapp.homepage" template="/layouts/classic.jsp"> <put-attribute name="title" value="Tiles tutorial homepage" /> <put-attribute name="header" value="/tiles/banner.jsp" /> <put-attribute name="menu" value="/tiles/common_menu.jsp" /> <put-attribute name="body" value="/tiles/home_body.jsp" /> <put-attribute name="footer" value="/tiles/credits.jsp" /> </definition> </tiles-definitions> ------------------------------------ * Render the definition After creating the definition, you can render it: * by using the <<<\<tiles:insertDefinition /\>>>> tag, inserting it in a JSP page: ------------------------------------- <%@ taglib uri="http://tiles.apache.org/tags-tiles" prefix="tiles" %> <tiles:insertDefinition name="myapp.homepage" /> ------------------------------------- * in other cases, you can render directly in the response, by using the Tiles container: ----------------------------------- TilesContainer container = TilesAccess.getContainer( request.getSession().getServletContext()); container.render("myapp.homepage", request, response); ----------------------------------- * by using {{{../advanced/utils.html}Rendering Utilities}} provided by Tiles. * by using a supporting framework. See {{{../integration/index.html}Integrations}} for a list of supporting frameworks.
