Tags as template parameters?
Hello list,
in Struts2 it is possible to do something like
<html>
<body>
<s:myMainNavigationMenu />
<h1>A page</h1>
<p>Some content</p>
</body>
</html>
This works ok, but my problem is that I have to change every single
page, if i would like to have a custom footer for every page, for example.
Now my question is: Is it possible to do something like this?
<s:useTemplate name="myCommonTemplate">
<s:setTemplateTag name="body">
<h1>A page</h1>
<p>Some content</p>
</s:setTemplateTag>
</s:useTemplate>
And as template definition say
<!-- Main menu -->
<table>...</table>
<s:insertTemplateTag name="body" />
<!-- Footer -->
<p>This is the footer</p>
I know it is possible to use parameters for templates, but they
obviously have huge limitations as I can't just put the tags there as I
did in my example.
Also, I could do something like
<s:myMainTemplate>
<s:param name="bodyPage" value="page1.jsp" />
</s:myMainTemplate>
which I also don't want because I would have an extra (unnecessary) page.
So, is it possible to pass whole XML-Structures to templates? Maybe you
have some reasons why I shouldn't want what I'm suggesting here, I would
be eager to hear them! :-)

Dave,
You're a valuable resource to the Struts board! Pascal should pay
attention to what you say.

Sitemesh doesn't build the entire page... it is a Filter that grabs the
response text (immediately before the servlet container sends it to the
client) and adds to it. Decorators contain what is added to the
response. I've found that if your decorators require a lot of run-time
logic then yes, it will take more time then if it were never modified.
(Exactly how much time depends on the decorator's logic.) Otherwise,
the time to decorate a page is negligible. Be smart when writing your
decorators... for instance, mapping different decorators to the
diverging URI patterns is an easy way to avoid the time penalty
associated with logic in decorators.

I just had a look at Sitemesh and it looks like what I want. There is one
thing that disturbs me, though, it looks as if sitemesh will build the page
every request, which causes quite some overhead, or am I mistaken there?

I'm on my phone so I only skimmed your message. If I read correctly,
you should take a look at sitemesh.
