maybe running Java within an XSL?

[Noah Mittman <na...@mac.com>]

What would be the best way to approach this functionality?

I have an XML which acts as source data for a multi-framed web 
application.
At some point I want a FORM in one of those HTML pages to send email -- 
take the to: and from: addresses but use a set of parameters which are 
nodes in the XML.

So basically I want, upon submission, for Cocoon to take the parameters, 
take the necessary nodes  from the XML, send email via javax.mail, and 
then style a result page based on the success/fail of the send, also 
using parameters in the source XML.

Here's an example of what I'd thought I'd do:

a) Create an XSP by pulling in what is needed from the source XML and 
the items from the FORM into a <xsp:page> root and a new <apputil:mail> 
element:

	<map:match pattern="sendmail.xsp"><!-- the action of the FORM -->
		<map:generate src="sourcedata.xml" /><!-- our source data -->
		<map:transform src="sourcedata-to-sendmail.xsl">
			<map:parameter name="use-request-parameters" value="true"/>
		</map:transform>
		<map:serialize type="xml"/>
	</map:match>

So a doc that is like this:
	<source>
		<name>Foo</name>
		<style>bar.css</style>
		<message>Thanks for making Foo #1 in Lichtenstein.</message>
	</source>
Becomes this:
	<xsp:page>
		<apputil:mail>
			<!-- form bits -->
			<name>Foo</name>
			<style>bar.css</style>
			<message>Thanks for making Foo #1 in Lichtenstein.</message>
		</apputil>
	</xsp:page>

b) have apputil logicsheet ready, which will turn apputil:mail into a 
<result> element

c) Execute the XSP and style the result

	<map:match pattern="mail.xsp">
		<map:generate type="serverpages" src="cocoon:/sendmail.xsp" />
		<map:transform src="mail.xsl"/><!-- xsl logic based on the 
result element -->
		<map:serialize type="html"/>
	</map:match>

It seems like it should be much easier than this, however. Is there a 
better way?
Thanks!
