Subject NoSuchDefinitionException when I try to display my page
Date Sat, 06 Oct 2007 11:16:13 GMT
Hi, i'm trying to use Tiles with a very simple sample, here is my 
configuration :

--- --- --- File WEB-INF/web.xml --- --- ---
...
...
        <!-- Tiles configuration -->
        <servlet>
                <servlet-name>tiles</servlet-name>
                
<servlet-class>org.apache.tiles.web.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>

...
...


--- --- --- File WEB-INF/tiles-defs.xml --- --- ---

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE tiles-definitions PUBLIC
       "-//Apache Software Foundation//DTD Tiles Configuration 2.0//EN"
       "http://tiles.apache.org/dtds/tiles-config_2_0.dtd">

<definition name="homepage" template="/index2.jsp">
        <put-attribute name="header" value="/header.jsp" />
        <put-attribute name="leftmenu" value="/leftmenu.jsp" />
        <put-attribute name="centerarea" value="/centerarea.jsp" />
        <put-attribute name="rightmenu" value="/rightmenu.jsp" />
        <put-attribute name="footer" value="/footer.jsp" />
</definition>


--- --- --- File index.jsp --- --- ---

<?xml version="1.0" encoding="UTF-8" ?>
<%@ taglib uri="http://tiles.apache.org/tags-tiles" prefix="tiles"%>
<tiles:insertDefinition name="homepage" />



When I try to acces the index.jsp page JBoss AS display me those errors :
...
...
12:55:17,212 INFO  [BasicTilesContainer] Initializing Tiles2 container. . .
12:55:17,248 INFO  [BasicTilesContainer] Tiles2 container initialization 
complete.
12:55:17,249 INFO  [TilesAccess] Publishing TilesContext for context:

        at 
org.apache.tiles.jsp.taglib.InsertDefinitionTag.render(InsertDefinitionTag.java:63)
...
...


If I delete everything in the file tiles-defs.xml and put those lines in 
index.jsp it works :
<tiles:insertTemplate template="/index2.jsp">
    <tiles:putAttribute name="header" value="/header.jsp" />
    <tiles:putAttribute name="leftmenu" value="/leftmenu.jsp" />
    <tiles:putAttribute name="centerarea" value="/centerarea.jsp" />
    <tiles:putAttribute name="rightmenu" value="/rightmenu.jsp" />
    <tiles:putAttribute name="footer" value="/footer.jsp" />
</tiles:insertTemplate>


So why a NoSuchDefinitionException appears when I'm using a tiles's 
definition ?

Thanks,


Baptiste GAILLARD
