Saving the output from a JSP request

Question

I have developed a decision support web site that amongst other things generates a "report" page. Now my client would like to add the ability for users of the site to have that report emailed out to them.
Sending the email obviously isn't a problem, but getting the content into it is. I really don't want to have to duplicate all the JSP code from the report page (there's a lot, including calls to beans etc), and reformat the entire thing with hundreds of out.write("<table>") like statements, or nasty plain-text formatted equivalents.
So...is there a way to "save" the output generated by the server before it gets sent back to the user - ideally to a local file that I can then just dump straight into the email message. I can't just call the page (internally on the server) to see its output, as it's user-specific and uses a lot of session-related information.
Cheers for any advice...

Answer 1

It's actually possible to do what I want to do by getting the server to call the page internally (I didn't think it was).
A simple URLConnection to the appropriate page with the jessionid appended gives me back the page as the user would see it. I can then just stream the response from that to file/email/whatever.
When the user clicks on their "email" link, I just call a jsp file (or a servlet) with the following code:
     URLConnection uc;
        BufferedInputStream fin;
     BufferedOutputStream fout;
     String location = "http://localhost:8080/blah/report.jsp"
          + ";jsessionid=" + session.getId();
     String filename = "C:\\output.html";
     try
          uc = new URL(location).openConnection();
          fin  = new BufferedInputStream(uc.getInputStream());
          fout = new BufferedOutputStream(new FileOutputStream(filename));
          int byteRead = fin.read();
          while (byteRead != -1)
               fout.write(byteRead);
               byteRead = fin.read();
          fout.close();
          fin.close();
     catch (Exception e) {}Now all I have to do is go learn how to write multipart emails using JavaMail...
