apache + tiles2 layout problem

Hi All,

First of all, pardon me if I'm asking a wrong question here.. new to the
mailing list

I have the following tiles configuration file



<tiles-definitions>
    <definition name="base" template="/includes/layout.jsp">
        <put-attribute name="header" value="/includes/header.jsp" />
        <put-attribute name="menu" value="/includes/menu.jsp" />
        <put-attribute name="footer" value="/includes/footer.jsp" />
    </definition>
    <definition name="home" extends="base">
        <put-attribute name="contentBody" value="/home/view.jsp" />
    </definition>
</tiles-definitions>
and to display "view.jsp" page I have another page called "home.jsp" and it
has the following code (only)

//home.jsp

<%@ taglib uri="http://tiles.apache.org/tags-tiles" prefix="tiles" %>
<tiles:insertDefinition name="home" />
and the problem here is, If i want to load "edit.jsp" page with same layout,
I need to repeat this part in tiles.xml

<definition name="editbase" extends="base">
            <put-attribute name="contentBody" value="/home/edit.jsp" />
</definition>
and create a file called "editbase.jsp" and call it. (repeating the above
code)

I'm just wondering is this the correct way or can I do something like

<tiles-definitions>
        <definition name="base" template="/includes/layout.jsp">
            <put-attribute name="header" value="/includes/header.jsp" />
            <put-attribute name="menu" value="/includes/menu.jsp" />
            <put-attribute name="footer" value="/includes/footer.jsp" />
        </definition>
        <definition name="home" extends="base">
            <put-attribute name="contentBody" value="/home/view.jsp" />
            <put-attribute name="contentBody" value="/home/edit.jsp" />
        </definition>
</tiles-definitions>
and load the page accordingly.. I think my question is clear

I'm using apache tiles 2.2.2

thanks in advance

Currently the only example I am aware of is tiles-test webapp, available in
Tiles distribution or here;
http://svn.apache.org/repos/asf/tiles/framework/trunk/tiles-test-pom
(it is a modularized Maven project with three modules, tiles-test contains
the "real" code you need)
<http://svn.apache.org/repos/asf/tiles/framework/trunk/tiles-test-pom>It has
a single link that uses the definition filter: "Test Tiles Definition
Filter" (yeah I know, there's a typo, not "definition" but "decoration").

Hi @Antonio

Thanks for the reply, I have been working with java web projects around 6
months and I think I can manage basics (JEE). :D.. And I'll be thankful if
you could direct me to some resources / examples of 'TilesDispatchServlet'
usage examples

thanks in advance

cheers

I am replying in the mailing list since it is more appropriate.

I suppose that the best thing to do is learning from a tutorial. If you are
new to Java at all, I suggest to start here:
http://www.roseindia.net/java/
<http://www.roseindia.net/java/>Better know the basics of Java and Java EE
(it's called "JEE 5" in the page linked above), after that you are ready for
Tiles.

You cannot put two attribute values to one attribute. Never tried, but I
think the last one wins.
So the first part of your code works.

Correct if I am wrong, but do you want a website that has the same layout
everywhere, with the exception of "contentBody" part?
If yes you might be interested in TilesDecorationFilter:
