Thanks Marcello, To accomplish this goal, it seems to me you should be caring about the *response*, not the *request*, right? After all, it is the response that contains the markup that was generated by the server. The request will only contain the request parameters for this form, in the standard format defined by the HTML specification. If my assumption is correct, you should look at technologies that use a Servlet Filter to be able to capture a copy the rendered output, in addition to sending it to the browser. Using a Filter has the advantage of being something you can add without modifying the actual code that creates the HTML output, and then removed when you are finished with your testing. As to details of the technology, the SiteMesh[1] package has to do exactly what you are talking about ... buffer up the generated response, and then do something with it. SiteMesh is about transforming the generated output, which you are likely not interested in ... but examining the source code of the filter that SiteMesh uses should give you a big head start on figuring out how to implement something like this.

HTTP requests should not contain any HTML at all, so I'm not sure what you were expecting to read from the request. I'm starting to think that Dave Newton was on the right track, although it seemed like a hideous hack ;) So, correct me if I'm wrong, but it sounds like you want to put some server-side checks /outside/ your HTML-generating code in order to perform some quality-assurance on the outgoing HTML code. I think this is best done with a filter. - -chris -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.6 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFFv4B89CaO5/Lv0PARAm0DAKDD/MaKU+ZhVKsK7hziU8nSRVHSmQCgmrsQ vElcEzZcruaNNlTifc9gOqI= =b4U+ -END PGP SIGNATURE- - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Can you explain with a little example ?
http://www.phptr.com/articles/article.asp?p=26119seqNum=7rl=1
http://java.sun.com/developer/Books/javaserverpages/cservletsjsp/index.h
tml has a link (PDF) to the chapter about creating custom tags which
might also help.
In a nutshell, look at the tag's doAfterBody method (this is from the
first link):
public class FilterTag extends BodyTagSupport {
public int doAfterBody() {
BodyContent body = getBodyContent();
String filteredBody =
ServletUtilities.filter(body.getString());
//...etc.
body.getString() gives you the rendered contents of the tag's body.

R: [OT] RE: Error : request.getReader()
I've read what you suggested but the problem is that i need a submit tag in
other words, i need to process the request content after the user press a
specific button (the others are handled in a LookupDispatchAction subclass).
I think i need some more info to built this kind of tag. Do you know where i
can get more information to obtain the result ?
Thanks
