Quick question (nesting tags)

[Greg Lehane <gl...@h5technologies.com>]

Hello all,


  In my JSP I'm iterating through a vector I've stored in my ActionForm
bean, I write out information from the vector to the JSP and the end
result is a populated table on the JSP. What I would like to do is add a
form to each row on the table (as I iterate through), however, I need to
grab info from the form in order to populate the action= part of the
<html:form ...> tag.

  So, I attempt to write something like this for each iteration:

    <html:form action="/browseRec?action=open&recset=<bean:write
name="resultSetVO" property="title" filter="true"/>"> <html:submit
property="submit" value="open"/>

  However, compilation throws up a "Non matching extension tags error"
on the JSP. Presumably because have the nested <bean:write ...> tag.

  I know that this nesting works using regular HTML, but I would rather
use the custom tags. Hopefully this simply involves adding commas or
something!

  Thanks,

- Greg

Off-topic: JSP documents (Was: nesting tags)

[John Yu <jo...@scioworks.com>]

This raises an interesting question.

"JSP documents", the XML verion of JSP, is defined in JSP spec 1.2 (Let's 
call them xJSP.) I think Tomcat 4.0 implements it.

In xJSP, expressions like <%= blah %> are represented as

   <jsp:expression>blah</jsp:expression>

So, does a JSP 1.2 compliant JSP container handles an xJSP containing 
something like:

   <html:form action="<jsp:expression>blah</jsp:expression>">

which is equivalent to this in normal JSP:

   <html:form action="<%= blah %>">

Or, is there a different approach to acheive the same effect?

Everyone wants to do this.  Unfortunately JSP syntax doesn't allow it. 
 The best you can do in a tag attribute is a scriptlet (<%= ... %>).
