Thanks to all who replied. I'll look into each suggested solution more
closely.

I don¹t know if it is possible to change a tiles definition at
runtime but
a solution to your problem could be solved by specifying a
definition that
uses a jsp file that does a conditional include according to a given
parameter?
definition name=choose.def extends=base.def
put name=header value=/header.jsp/
put name=body value=/choose.jsp/ -
put name=footer value=/footer.jsp/
/definition
choose.jsp

Re: [Tiles] Populating Tiles definition attribute at runtime
The cleanest thing to do here, likely, would be to have your 'content'
attribute have a value that maps to an Action (/search.do would work, I
think - Vic might be able to confirm this) and in the Action class,
define an attribute heading stored in request context, that pulls from
request parameters. The tiles-defs.xml isn't really a dynamic
mechanism in any way - its a config file that is loaded - it isn't
treated as a JSP that gets compiled into a .java and then compiled to a
.class servlet.
Alternately, just set your heading attribute in tiles-defs.xml to be
Search or whatever you want, and in the /search.jsp file, use JSTL to
prepend param.myValue. This would be pretty clean for simple scenarios.

Re: [Tiles] Populating Tiles definition attribute at runtime
Hi Robert..
I guess you could achieve the same using the controllerClass attribute and
building your class.. For instance, I have this definition in the
tiles-defs.xml file:
---
definition name=.layout
path=/common/layout.jsp
controllerClass='com.dars.XTileAction'
put name=title value=Encabezado primario/
put name=leftsidevalue=/common/leftside.jsp/
put name=rightside value=/common/rightside.jsp/
put name=header value=/common/header.jsp/
put name=footer value=/common/footer.jsp/
put name=bodyvalue=/common/body.jsp/
/definition
---
And I have this controllerClass
---
package com.dars;
import org.apache.struts.tiles.actions.TilesAction;
import org.apache.struts.tiles.ComponentContext;
import org.apache.struts.tiles.Controller;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.ServletContext;
import javax.servlet.ServletException;
import java.io.IOException;
public class XTileAction extends TilesAction implements Controller{
public void perform(ComponentContext tilesctx,
HttpServletRequest request,
HttpServletResponse response,
ServletContext servctx)
throws ServletException, IOException{
/* GetAttributes */
String titulo= (String)tilesctx.getAttribute(title);
String derecha= (String)tilesctx.getAttribute(rightside);
/* GetAttributes */
System.out.println( Titulo: +titulo);
System.out.println( Derecha: +derecha);
/* SetAttributes */
tilesctx.putAttribute(title, Titulo nuevo de esta vaina..);
tilesctx.putAttribute(rightside, /common/footer.jsp);
/* SetAttributes */
}
}
---
You can change the values of those attributes at runtime. I prefer to do
it using this method.

Re: [Tiles] Populating Tiles definition attribute at runtime
I modified the ActionServlet (might not be necessary - need to investigate the dynamic
module config stuff further), created a new TilesDefinitionFactory and changed a few
other bits and made tiles extract all of its definitions from a database. I also
implemented a cache mechanism as a Java servlet so that database access was minimal.
This was all because I need a site that was truly dynamic, whilst running on a cluster
of servers.
