[Tiles] Populating Tiles definition attribute at runtime
Greetings, I have a tiles definition in my tiles-defs.xml similar to below:
<definition name="search" extends="layout">
<put name="heading" value="{0}Search" type="string" />
<put name="content" value="/search.jsp" type="page" />
</definition>
which I would like to be able to modify the "heading" value such that
at runtime I could substitute a value for {0}.
For example, it would be ideal to use a JSTL type of syntax such as:
<definition name="search" extends="layout">
<put name="heading" value="${param.myValue}Search" type="string" />
<put name="content" value="/search.jsp" type="page" />
</definition>
but this does not work.

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.

Wow, that's pretty cool ... I'll have to check out the controllerClass
stuff sometime :)

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="leftside" value="/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="body" value="/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.
Atte.

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

Re: [Tiles] Populating Tiles definition attribute at runtime

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
<c:import url='/WEB-INF/com/website/tiles/choose/${request.choose}'/>
