Reading generated html

Hi all.
I need to read in a Bean the generated html (i mean the one interpreted
by the browser).
Let me explain further:
In a jsp file i've this piece of code:

[...]
<html:form action="/someAction">
[...]
<jsp:useBean id="myObj" class="util.Test" scope="request">
<jsp:setProperty name="myObj" property="html"
value="<%=request%>"></jsp:setProperty>
</jsp:useBean>
[...]
</html:form>
[...]

This is the bean:

package util;
import javax.servlet.http.HttpServletRequest

Source code of javax.servlet.http.HttpServletRequest

;
import javax.servlet.ServletInputStream

Source code of javax.servlet.ServletInputStream

;
import java.io.InputStreamReader

Source code of java.io.InputStreamReader

;
import java.io.BufferedReader

;;
public class Test {

public Test(){
}
public void setHtml(HttpServletRequest request){
StringBuffer HTMLStr=new StringBuffer("");
ServletInputStream content=request.getInputStream();
BufferedReader br = new BufferedReader(new
InputStreamReader(content));
HTMLStr.append(br.readLine());
}
}

But i get no HTML string, always get a null string !
I suppose the bean method is invoked before tha page was rendered, but i
can figure out how invoke the bean after.
Even an alternative approach will be intersting for me.

Any help will be greatly appreciated
Thanks in advance
