Java - Return jsp paramaters to another machine

01-26-2004, 03:08 PM

Good afternoon!
I am working with Apache and Tomcat in two different machines, and I
can access jsp pages in the Apache machine (connector mod_jk). The
problem is: I want to separate the HTML code(Apache machine) and de
JSP code (Tomcat machine). Its possible returns parameters from jsp to
the other machine (Apache)? And how can I do this?

theres a example for view the problem:

Machine (Apache)

Example.html

<html>
<body>
<h1>users list</h1>
<table>
<tr>

</tr>
</table>
</body>
</html>

Machine (Tomcat)

users.jsp

for (int i=0; i<users.length; i++) {
uilizador = (String) users[i];
out.println("<td>" + users + "</td>");
}
I would like to return the users list to the apache machine, and there
make the print.

P.S.- I am sorry, my English is not very good. In case of any question
please contact.

No, I don't think that what you want is possible. I'm also unsure why
you'd want to do it. The whole point of a JSP is to contain HTML with
some dynamic content. There's absolutely nothing wrong with placing
HTML in JSP files. (In fact, if you're all-out avoiding HTML in your
JSPs, then it's kinda wasteful to use JSPs at all; may as well stick
with servlets.)

Hello Chris.
What I want to do is connect many web servers (apache) to one web
server (tomcat), and every web server (apache) have a different site,
but just in look and feel, the functionalities are the same and they
must be in the tomcat machine. Because just that machine can access to
BD and make operations, and security is very important.

Thanks. Márcia Elias

Okay. I would very strongly consider a different approach. What you've
got going there is one of the least flexible and most difficult means of
achieving this task. Off-hand, here's a strategy that I'd look into
instead, were I in your place.

Have your back-end process return data in something other than an HTML
fragment. The HTML fragment is one the least understandable (and
therefore hardest to customize) forms you could possibly choose for that
data. If it's important to you that it be easy to convert the data to
HTML, then an XML-based format might work well, and XSL could be used to
format the presentation layer.

(As I said earlier, I cannot think of a clean way to do what you
originally asked.)

Hello Chris.
Tanks for your suggestion, I think I would use XML format, so I can
interpret the results.
