You need to define the laytou of your pages? Did you define where Tiles
should put title and content? If not, he can't compose your page.
Take a look now in the path attribute.
<definition name="tiles.view" path="myLayout.jsp">
<put name="title" value="PAGE TITLE"/>
<put name="content" value="/tiles-test/index.jsp"/>
</definition>
The myLayout.jsp contents could be:
<%@ taglib uri="/WEB-INF/struts-tiles.tld" prefix="tiles" %>
<html>
<head>
<title><tiles:insert attribute="title" />
<body>
<tiles:insert attribute="content" />
</body>
</html>
Hope this helps.

Subject: Using tiles
This is a newbie question on using the Tiles with Struts (never tried it
before). I followed the instructions in the first half of Tiles 101/201,
linked from the Tiles documentation but am having no luck on the
Struts/Tiles integration front. I suspect I've simply missed a step
somewhere.
Here's what I've done:
* Ensured Tiles is enabled in struts-conf.xml (it was by default):
<plug-in className="org.apache.struts.tiles.TilesPlugin" >
<set-property property="definitions-config"
value="/WEB-INF/conf/tiles-defs.xml" />
<set-property property="moduleAware" value="true" />
<set-property property="definitions-parser-validate" value="true" />
</plug-in>
* added a tile definition to teils-defs.xml:
<definition name="tiles.view">
<put name="title" value="PAGE TITLE"/>
<put name="content" value="/tiles-test/index.jsp"/>
</definition>
* added an action mapping to struts-conf.xml pointing to the tile:
<action path="/tiles"
type="DummyTilesAction">
<forward name="view" path="tiles.view"/>
</action>
* created /tiles-test/index.jsp with some static text content
What I expected was that when I hit /tiles.do I'd get back the static
content from /tiles-test/index.jsp. What I actually get back is the
string '<html><body></body></html>', which I haven't defined anywhere.
I also tried implementing execute() in DummyTilesAction to do a 'return
mappings.findForward("view");' but no luck. Changing the name of the
view in struts-conf.xml or tiles-defs.xml makes no difference, and
generates no error messages when they don't match, which makes me
suspicious...
The tiles defs do seem to be read in on startup:
L4J 2004-03-15 19:22:47,801 DEBUG

path=/tiles.layout.basic.jsp, role=null, controller=null,
controllerType=null, controllerInstance=null, attributes={title=DEFAULT
TITLE, content=/tiles.content.default.jsp,
menu=/tiles.layout.basic.menu.jsp}}
, tiles.view={name=tiles.view, path=null, role=null, controller=null,
controllerType=null, controllerInstance=null, attributes={title=PAGE
TITLE, content=/tiles-test/index.jsp}}
}
L4J 2004-03-15 19:22:48,065 DEBUG

L4J 2004-03-15 19:22:48,065 INFO org.apache.struts.tiles.TilesPlugin
Tiles definition factory loaded for module ''.
and the action mapping was picked up correctly; when I hit /tiles.do I
get this logged:
L4J 2004-03-15 19:25:49,791 DEBUG
org.apache.struts.action.RequestProcessor Looking for Action instance
for class DummyTilesAction
But no Tiles related logging, and the page specified in the tile
definition isn't loaded. The taglib documentation at
http://jakarta.apache.org/struts/userGuide/struts-tiles.html says that I
have to call initComponentDefinitions or otherwise arrange to have Tiles
initialized. I thought the configuration in struts-conf.xml would make
that happen, but tried calling the tag in case. That didn't seem to help.
What am I doing wrong? If I've left any information out, please ask and
I'll post it.
Thanks,
L.
