Jason,
it just occurred to me (must have had my eyes shut) after a couple of
weeks that the last breadcrumb in the breadcrumb menu done with your
tiles method is actually a link to the page that you are already on.
Is this the way you have implemented it, or have I done it wrong?
Yes, it is a link to that page. Or at in some cases it has been the
link to the list page for some admin pages. Eg list of users, when they
select a user to edit i leave the breadcrumb as 'Users' and if they
click on it, it goes back to the user list.

Hi all,
Is there any slick way of putting breadcrumbs into a web app with
Struts? If so, what's the preferred way?
Thanks.

I did this using tiles. I have my tiles extending a base layout, then
each sub-menu item extends the parent tile definition
eg
(first level)
<definition name=".main.admin" extends=".layout">
...
</definition>
(second level)
<definition name=".main.admin.workflow.list" extends=".main.admin">
...
</definition>
Now, for breadcrumbs I would define breadcrumb0 in the first level. As
the second level extends the first, breadcrumb0 will be included. In
the second level I define breadcrumb1
eg
<definition name=".main.admin" extends=".layout">
<put name="title" value="admin.title" />
<put name="body" value="/WEB-INF/jsp/tiles/admin/admin.jsp" />
<putList name="breadcrumb0" >
<item value="admin.menu"
link="admin"
tooltip="admin.title"
classtype="org.apache.struts.tiles.beans.SimpleMenuItem" />
</putList>
</definition>
<definition name=".main.admin.workflow.list" extends=".main.admin">
<put name="title" value="workflow.list.title" />
<put name="body"
value="/WEB-INF/jsp/tiles/admin/workflow/list.jsp" />
<putList name="breadcrumb1" >
<item value="workflow.menu"
link="workflowlist"
tooltip="workflow.title"
classtype="org.apache.struts.tiles.beans.SimpleMenuItem" />
</putList> </definition>
I had originally wanted to just to be able to add an item to the
breadcrumb list, but that is not possible in xml. In my layout.jsp page
I then use
<tiles:useAttribute name="breadcrumb0" ignore="true" />
<tiles:useAttribute name="breadcrumb1" ignore="true" />
<tiles:useAttribute name="breadcrumb2" ignore="true" />
<!-- breadcrumbs -->
<div class="breadcrumbs">
<span class="breadcrumb mainnavitem"><html:link
forward="homepage" titleKey="homepage.title"><bean:message
key="homepage.menu" /></html:link></span>
</c:forEach>
<c:forEach items="${breadcrumb0}" var="crumb">
<span class="breadcrumb mainnavitem"><bean:message
key="breadcrumb.separator" /> <html:link forward="${crumb.link}"
titleKey="${crumb.tooltip}"><bean:message key="${crumb.value}"
/></html:link></span>
</c:forEach>
<c:forEach items="${breadcrumb1}" var="crumb">
<span class="breadcrumb mainnavitem"><bean:message
key="breadcrumb.separator" /> <html:link forward="${crumb.link}"
titleKey="${crumb.tooltip}"><bean:message key="${crumb.value}"
/></html:link></span>
</c:forEach>
<c:forEach items="${breadcrumb2}" var="crumb">
<span class="breadcrumb mainnavitem"><bean:message
key="breadcrumb.separator" /> <html:link forward="${crumb.link}"
titleKey="${crumb.tooltip}"><bean:message key="${crumb.value}"
/></html:link></span>
</c:forEach>
</div>
<!-- end breadcrumbs -->
Hope that make somes sort of sense. If not ask me a question and I will
try to explain better.
