template:put and get
I've got a situation where I want to include a header file with
<template:insert template="/share/inc_header.jsp">
<template:put name="header_image" content="/media/h_modify.gif" direct="true"/>
</template:insert>
and then in the header file have
<html:img page="/media/h_modify.gif" width="315" height="23" border="0"/>
but replace the page="" with the <template:get/>. Trouble is you can't nest
tags. One options is to do the html without the jsp, and have
<img src="<%= request.getContextPath() %>/media/h_modify.gif" width="315" height="23" border="0"/>
but that doesn't look great, but I can't think of anything else. The <template:put/>
seems to hide the content away somewhere away in the request, and I don't want to
create 20 little html/jsp pages for the different headers that I have.
Any ideas?

So far we have access to the values of template placeholders only via
template:get. You can write your own tag to define registered
template placeholders as page scope beans and
access such values via bean:write tags or use it in html:img tag. I
think it will be good template mechanism enhanesment.

You can place whole html:img tag to the template:put tag as its
content and cut content and direct attributes.

I think <template:put> tag puts the contents (="/media/h_modify.gif)in some
hashtable on the stack . and <template:get> tag retrieves that content from
hashtable and includes in the pageContext which displays it . so I think u
can put anything in the header.jsp
