You just have to include following script.

<script language="javascript" type="text/javascript">  
        var xmlHttp  
        function showState(str)
        {
            //if you want any text box value you can get it like below line. 
            //just make sure you have specified its "id" attribute
            var name=document.getElementById("id_attr").value;
            if (typeof XMLHttpRequest != "undefined")
            {
              xmlHttp= new XMLHttpRequest();
            }
            var url="forwardPage.jsp";
            url +="?count1=" +str+"&count2="+name";
            xmlHttp.onreadystatechange = stateChange;
            xmlHttp.open("GET", url, true);
            xmlHttp.send(null);
        }
        function stateChange()
        {   
            if (xmlHttp.readyState==4 || xmlHttp.readyState=="complete")
            {   
                document.getElementById("div_id").innerHTML=xmlHttp.responseText   
            }   
        }
      </script>

So if you got the code, let me tell you, div_id will be id of div tag where you have to show your result. By using this code, you are passing parameters to another page. Whatever the processing is done there will be reflected in div tag whose id is "div_id". You can call showState(this.value) on "onChange" event of any control or "onClick" event of button not submit. Further queries will be appreciated.

I am trying to Understand your Question and it seems that you want the values in the first JSP to be available in the Second JSP    It is very bad Habit to Place Java Code snippets Inside JSP file  so that code snippet should go to a servlet  Pick the values in a servlet ie   String username   request getParameter  username    String password   request getParameter  password     Then Store the Values inside the Session   HttpSession sess   request getSession     sess setAttribute  username   username   sess setAttribute  password   password    These values Will be available anywhere in the Application as long as the session is valid   HttpSession sess   request getSession false     use false to use the existing session sess getAttribute  username     this will return username anytime in the session sess getAttribute  password     this will return password Any time in the session    I hope this is what you wanted to know  but please do not use code snippets in the JSP  You can always get the values into the JSP using jstl in the JSPs      username   this will give you the username in the JSP    password    this will give you the password in the JSP

I dont exactly know what you want to do But you cant send data of one form using a submit button of another form   You could do one thing either use sessions or use hidden fields that has the submit button  You could use javascript jquery to pass the values from the first form to the hidden fields of the second form Then you could submit the form   Or else the easiest you could do is use sessions    lt form gt   lt input type  text  class  input-text   value    size  32  name  user data firstname   id  elm 6  gt   lt input type  text  class  input-text   value    size  32  name  user data lastname   id  elm 7  gt   lt  form gt    lt form action     gt   lt input type  text  class  input-text   value    size  32  name  user data b firstname   id  elm 14  gt   lt input type  text  class  input-text   value    size  32  name  user data s firstname   id  elm 16  gt    lt input type  submit  value  Continue  name  dispatch checkout update steps   gt   lt  form gt       input type submit    click function        elm 14   val     elm 6   val         elm 16   val     elm 7   val           This is the jsfiddle for it http   jsfiddle net FPsdy 102

You could do it in either of this ways   triggering an onclick on a form button like this    lt form id  myform  name  myform  method  post  action  demo2 jsp  gt       lt input type  text   name  usnername    gt       lt input type  text  name  password   gt               lt input type  button  value  go  onclick  submitForm    gt   lt  form gt    And using javascript           function submitForm                                 document forms 0  submit                return true              or you could also try Ajax to post your page   here is the link jQueryAjax  And also nice startup examples using Ajax and here  Hope this helps
