java template emailer

["Chad Smith" <csmith@cimaconsulting.com>]

I'm trying to create a marketing campaign emailer  for a client that
will let me send out a template JSP file that i will populate with data
from a data source.
For example, I have a TreeSet of data where each index holds personal
information about a user (name, email address, city, etc.)
I want to send out an HTML/JSP email as follows:
 
Hello <%=NAME%>,
 
Thank you for purchasing <%=PRODUCT%>.
Please let us know if you are satisfied with the product:
 
<HERE IS A DROPDOWNLIST>
Very Satisfied
Satisfied
Not Satisfied
You're Awful
<END LIST>
 
<SAVE>
 
Now the problem i'm having is ...I know how to display this information
for each person in the TreeSet (using a forward or include), but
how do i send the completed jsp/html email to that person?
 
 I know that I can do the following:
 
URL thePage = new URL("http://www.yoursite.com/yourjsp.jsp";);
URLConnection conn = thePage.openConnection();
InputStream is = conn.getInputStream();
 
 // read from this InputStream
Then you can direct the data from that InputStream into the e-mail body.
 
But i'm pretty sure this will send out the jsp without having first
compiled it.
I need to figure out a way to either compile the jsp and then send it,
or compile it to some sort of .html file and send it.
I also need to find the most efficient way of doing this since  the
client could be sending large campaigns of emails.
 
Thanks for your time!
