How to implement jsp:forward...

Question

I included a <jsp:forward...> directive in my jsp page.
How do I tell that it has only to be executed when
a 'submit' button is pushed ?
Can I add it to the 'action' attribute of a form?

sudhabharathi, yes I tried but remember, I want to create a html-jsp-servlet-jsp environment following the MVC2 rules. Thus jsp with only Beans, servlet which changes the info inside the Bean and forward request to another JSP which display's the info, etc...
When I change the code as :
<FORM action="com.clipper.beans.FQController" method=post target=_parent>
the servlet loads but I cannot get the bean-data into the servlet.
The code in servlet is as follows:
try
     FreightQuotation fq = (FreightQuotation) req.getAttribute("FQ");
     System.out.println("fq object created");
     System.out.println("fq.getGoodsDescription =" + fq.getGoodsDescription());
     FreightQuotationCBean fqc = (FreightQuotationCBean) req.getAttribute("FQC");
     System.out.println("fqc object created");
     System.out.println("fqc.aAS400data.getGoodsDescription() value =" + fqc.aAS400data.getGoodsDescription());
     getServletConfig().getServletContext().
          getRequestDispatcher("../jsp/quotagentdetail.jsp").
          forward(req, res);
catch (Exception e)
     System.out.println("FQController ended abnormally");
     e.printStackTrace();
where executions stops after the message 'fq object created'. The servlets fails at statement:
System.out.println("fq.getGoodsDescription =" + fq.getGoodsDescription());and prints the "FQController ended abnormally" message.
The fq.getGoodsDescription() is a valid getter!
This leads me to the fact that the servlet doesn't receive the bean...
