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

You just have to include following script    lt script language  javascript  type  text javascript  gt            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   amp 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                                      lt  script gt    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
