How to forward data from one jsp A to jsp B and then all data to final servlet?

I have two JSP pages A and B and also a Servlet.

The flow is like this:

User fill in some information in page A

Then the user fill in some other information in page B

After the user finishes B, he/she will click a button and submit all data (from both A and B) to the Servlet.

How should I design this?

My plan is

In A's next button, it is actually a <a> tag with link to the href of B. All information from A should be passed to B via that link. I don't know how to do this step.

In B's finish button, it is a form input submit button. I don't know whether I can or how I add A's data into this form.

Anyone can help me out?

Thanks

In your A.jsp create a link, for e.g.: <a href="B.jsp?param1=value1&param2=value2">Go to B</a> Pass your parameters from URL.

In B.jsp use expression language to get parameters values:

<form action="FinalServlet" method="post">

   <input type="text" name="p" value="your value"/>

   <input type="hidden" name="p1" value="${param.param1}"/>
   <input type="hidden" name="p2" value="${param.param2}"/>

   .......

   <input type="submit" value="Finish"/>

</form>

Hope this helps.

EDIT:

If you want to use a form with input fields in A.jsp:

<form action="B.jsp" method="post">

   <input type="text" name="param1" value="value1"/>
   <input type="text" name="param2" value="value2"/>

   .......

   <input type="submit" value="Finish"/>

</form>

You will receive parameters in B.jsp using the same EL.
