Please Help With Simple Tiles Problem
I'm using struts 1.1 and having trouble with a simple Tile function. I've searched the archives and doc, but for some reason I just can't seem to get a grip on a lot of this tile stuff. All I want to do is embed a tile within a tile within a page. Here's what I have now:
tiles-defx.xml (snippet)
=================================
<definition name="layout.default" path="/tls/layout.jsp">
<put name="title" value="my title" direct="true"/>
<put name="header" value="/tls/header.jsp"/>
</definition>
<definition name="form.default" extends="layout.default">
<put name="body" value="/tls/wrapform.jsp"/>
</definition>
<definition name="form.user" extends="form.default">
<put name="title" value="form title" direct="true"/>
<put name="form-body" value="/tls/user_form.jsp"/>
</definition>
In layout.jsp (snippet)
===================================
<tiles:insert attribute="body"/>
In wrapform.jsp (snippet)
====================================
<tiles:insert attribute="form-body"/>
I get an error saying that my "form-body" attribute does not exist. And when I swap <tiles:insert> with <tiles:get>, I don't get an error, but I also don't get my form-body content. I can see that what I have defined doesn't make much sense, but I can't figure it out.
What I want is, when I call "form.user" for it to give me the folloing content structure....
(if these tags represented the content of JSP's)
<layout.jsp>
<wrapform.jsp>
<user_form.jsp/>
</wrapform.jsp>
</layout.jsp>
Could someone please show me how to do this?
Thank you

Download modelj from sourceforge and try it. Supply the path to your
j2ee.jar and build the sample app in 2 minutes. Modelj will create a
struts/ejb application for you from one single config file. Using JBoss,
all you have to do is setup a default data source and deploy your
sample.ear.

Maybe EJB should be used with JSF (and blue prints
http://java.sun.com/blueprints/code/index.html) instead of Struts.
Struts is more like this http://ibatis.com/jpetstore/jpetstore.html.

There are two implementations of Xpetstore, one that uses EJB and one
that just uses servlets. Check out the EJB one, it works great with JBoss.
Note, I personally don't think that using EJB is fundamentally different
from any other persistence layer, at least not in reference to Struts,
so you should be able to look at just about any sample code and figure
out some best practices. It all boils down to the fact that you have
Struts Actions, which receive HTTP requests from the client, and which
then delegate the work to other objects. Whether those objects are
session beans that perform some task by calling EJB or Hibernate
objects, or whether you're going the simple route (what I'm doing b/c my
needs are so trivial) and just having your Struts Actions directly
manipulate Data Access Objects which use JDBC business delegates, it's
not really much different.
The only big difference I've seen is that some people believe you should
abstract your model into a layer just beyond Struts Actions so that you
can switch from Struts to another framework if necessary. But the other
line of reasoning is that this is a lot of extra work if you have no
plans to leave Struts.
My 2 cents.
Erik

Thanks. I've seen that page and many other. Believe, I feel stupid from seeing so many examples and not being able to figure it out. But I'm getting a mental block somewhere that just isn't allowing me to grasp something.

Re: Please Help With Simple Tiles Problem
Posted by Terry Brick <te...@yahoo.com>.
Ok, I've finally gotten this to work. However, I
don't think it's the "right" solution and it's
certainly not one I'm happy with. But maybe by
showing how I'm getting it to work, that will better
communicate to people what I'm trying SO HARD to do.
This works:
<definition name="page" path="page.jsp"/>
<definition name="form1" extends="page">
<put name="body" value="form1a"/>
<definition>
<definition name="form1a" path="form_wrapper.jsp">
<put name="form-body" value="form1.jsp"/>
</definition>
So this gives me...
<page.jsp>
<form_wrapper.jsp>
<form1.jsp/>
</form_wrapper.jsp>
</page.jsp>
The problem is that "form1.jsp" will not always be
"form1.jsp". I want to be able to swap that for a
"form2.jsp", "form3.jsp", etc. Using this method, I
would have to add TWO definitions into the
tile-defs.xml for each new form I wanted! (form2,
form2a, form3, form3a, etc)
There must be a better way where I only have to add a
single definition for each new form. Any ideas?
Advice is much appreciated. Thanks.
