How to Send current Textfield values through URL?

Question

I want to send values of my textfields of JSP/HTML page through URL like this:

<a href="some.jsp?uname=Somnath&dob=02/02/89&gender=male"></a>

But instead of static value I need to send the value which is putted currently.
Actually I want to receive the value of all fields by getParameter() method. But we can not use:

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

Because there is anothere URL attached with the form.Actual Situation is:

<form action="someAnother.jsp" method="post">
  <input type='text' name='uname'/>
  <input type='password' name='password'/>
  <input type='text' name='dob'/>
  <input type='text' name='contact'/>
  <a href="some">
    <input type='button' value='Upload Image'/>
  </a>
  <input type='submit' value='Register'/>
</form>

UploadImage Button call a servlet & make some operations and forward to this page again. And I need to fill all fields again which was filled by the user before hit the Upload Image Button.
So I think only way to get those values in that servlet is through URL.Please give me your suggestion.

Remind that we can get all the field values in a JSP/Servlet only if we make the action through form tag & also remind the nested form is not allowed.
So only way to call another servlet/jsp within a form tag again is a tag but it Carries no data with it.If i want to send some data with a tag then we have to use URL like firs Example.

Add upload button outside of form tag( before or after
) or use ajax — Navnath Godse, Apr 22 '13 at 09:12

Alternative 1:

Change

method="post"

to

method="get"

Alternative 2: Submit the above form data to a servlet (BasicInfoServlet). In this servlet, save the received data in session and the redirect/forward the user to image upload page. Submit the image upload form to a second servlet (ImageInfoServlet). In the second servlet write code to save/process the image and initial data from session.

I want to Receive all fields in "some" servlet not in "someAnother.jsp". – Somnath Kayal Apr 22 '13 at 09:22
To receive all the fields in `some` servlet, specify the name of `some` servlet in the form's action attribute. – Apurv Apr 22 '13 at 09:23
I mean change `
` to `
`. This will send all the parameters to the `someServlet`

In this page two action is required (1) For Registration (2) For Upload a File. Please read the question again. – Somnath Kayal Apr 22 '13 at 09:44

Use "get" method.

Code :-

<form action="/servleturl_mappingpath" method="get">
  <input type='text' name='uname'/>
  <input type='password' name='password'/>
  <input type='text' name='dob'/>
  <input type='text' name='contact'/>
  <a href="some">
    <input type='button' value='Upload Image'/>
  </a>
  <input type='submit' value='Register'/>
</form>

If you method is get, the requested data will be visible on URL.

When you click on Register Button, the request will go to the given servlet ( /servleturl_mappingpath) .

Now, you can get in servlet as below :

String namee=request.getParameter("uname"); 
String pass=request.getParameter("password"); 
String dobb=request.getParameter("dob"); 
String contactt=request.getParamenter("contact");

Use the above code in your servlet. And finally redirect your response to any given JSP.

Hope it will help you.

Use POST method and the enctype attribute of the form has to be set to "multipart/form-data"
