Subject [jira] [Commented] (WW-4161) Incorporate tiles3 into conventions, tutorial (and add code to tiles3 plugin)
Date Fri, 11 Jul 2014 08:42:04 GMT

    [ https://issues.apache.org/jira/browse/WW-4161?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14058556#comment-14058556

Christoph Nenning commented on WW-4161:
---------------------------------------

You need a tiles.xml which defines a layout:

--------------------------------------------
tiles.xml
--------------------------------------------
<tiles-definitions>
    <definition name=".default-layout" template="/WEB-INF/tiles/layout/layout.jsp">
        <put-attribute name="titleMsgKey" value=".titleMsgKey" />
        <put-attribute name="content" value=".content" />
    </definition>

    <!-- no more entries ! -->
    <!-- except you have several layouts -->
</tiles-definitions>



Then you can annotate actions. Annotations reference the layout and provide paramters:
--------------------------------------------
SampleAction
--------------------------------------------
@Result(name=SampleAction.INPUT, type="tiles-annotation")
@TileDef(
        extend=".default-layout",
        attributes={
                @TileAttribute(name="titleMsgKey", value="text.key.test"),
                @TileAttribute(name="content", value="/WEB-INF/tiles/test/test.jsp")
        }
)
public class SampleAction extends ActionSupport {
...
}


And an entry in web.xml is required:
--------------------------------------------
web.xml
--------------------------------------------

<!-- a parameter for TilesListener is required which I wrapped in a specialized context
listener -->
<!-- that parameter is:
		<param-name>org.apache.tiles.factory.TilesContainerFactory.MUTABLE</param-name>
		<param-value>true</param-value>
-->
<listener>
		<listener-class>
			org.apache.struts2.tiles.StrutsTilesAnnotationsListener
		</listener-class>
		<init-param>
				<param-name>org.apache.tiles.impl.BasicTilesContainer.DEFINITIONS_CONFIG</param-name>
				<param-value>/WEB-INF/classes/tiles.xml</param-value>
		</init-param>
</listener>

> There is a description found here: http://stackoverflow.com/questions/11161194/freemarker-and-struts2-tags
> It would be good if the struts2 website could turn the following into a tutorial, possibly
some of the code could be included into the tile3 plugin but I'm not convinced at this time
that should be done.
