Problem with Tiles

[Deepesh Nandal <de...@eth.net>]

Hi There,
   I am stuck at one place while working with tiles, please help.
I have my tiles-defs.xml as this:

<tiles-definitions>
 <definition name=".mainLayout" path="/WEB-INF/tiles/layout.jsp">
  <put name="title"  value="Welcome to Net Model"/>  
  <put name="pageheading"  value=""/>  
  <put name="header" value="/WEB-INF/tiles/header.jsp"/>   
  <put name="sider"  value="/WEB-INF/tiles/sider.jsp"/>
  <put name="body"   value=""/>
  <put name="footer" value="/WEB-INF/tiles/footer.jsp"/>
 </definition> 
 <definition name="index.page" extends=".mainLayout">
  <put name="pageheading" value="Login" />
  <put name="body"
   value="/WEB-INF/tiles/user-login.jsp" type="page"/>   
  </definition>
</tiles-definitions>

AND  /WEB-INF/tiles/layout.jsp  as this:
<%@ taglib uri="/WEB-INF/struts-tiles.tld" prefix="tiles" %>
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>
<html:html>
 <head> <title><tiles:getAsString name="title"/></title>
 <META http-equiv=Content-Type content="text/html; charset=UTF-8">
 <LINK href="style.css" type=text/css rel=stylesheet>
 </head>
 <body>
        <tiles:insert attribute="header" /><br>
 <tiles:insert attribute="sider" /><br>
 <tiles:insert attribute="body" /><br>
 <tiles:insert attribute="footer" />

 </body>
</html:html>

Now, I need to print the variable 'pageheading'( defined in definition '.mainLayout')  in "/WEB-INF/tiles/header.jsp" .
I cannot use <tiles:getAsString name="pageheading"/> inside "/WEB-INF/tiles/header.jsp"  as "pageheading" is valid in 
"/WEB-INF/tiles/layout.jsp" only . So how do I pass "pageheading" from "index.page" to header.jsp through .mainLayout ...

Please help .....

Many Thanks,
Deepesh Nandal.

There are 2 ways of doing it. 
1) Get the "pageheading" in the layout.jsp and pass it on to the header.jsp 

<tiles:insert attribute="header">
<tiles:put name="pageheading">
<tiles:getAsString name="pageheading" ignore="true"/>
</tiles:put>
</tiles:insert>

2) If you need the "pageheading" inside the heading.jsp, it's better to make 
the "header" a separate definition and use the "pageheading" directly in the 
header.jsp

<tiles-definitions>
<definition name=".mainLayout" path="/WEB-INF/tiles/layout.jsp">
<put name="title" value="Welcome to Net Model"/>
<put name="header" value=".header" type="definition"/>
<put name="sider" value="/WEB-INF/tiles/sider.jsp"/>
<put name="body" value=""/>
<put name="footer" value="/WEB-INF/tiles/footer.jsp"/>
</definition>

<definition name=".header" page="/WEB-INF/tiles/header.jsp">
<put name="pageheading" value=""/>
</definition>

<definition name=".login.header" extends=".header">
<put name="pageheading" value="Login"/>
</definition>

<definition name="index.page" extends=".mainLayout">
<put name="header" value=".login.header" type="definition"/>
<put name="body" value="/WEB-INF/tiles/user-login.jsp" type="page"/>
</definition>
</tiles-definitions>
