You can always do this

<form action="page2.jsp" method="post">
<input type="text" name="Text1">
<input type="submit">
</form>


in your page2.jsp, you do this to get the text value
    request.getParameter("submit");

to print out the text, you do this

out.println(request.getParameter("Text1));

You will have to resubmit the page and retreve the parameter.

for example:

<%
  if (request.getParameter("myTextField") != null) {
%>   alert('Parameter found: <%=request.getParameter("myTextField")%>');
<%}
%>

<form method="post" name="myform" action="#">
  <input type="text" name="myTextField" onBlur="this.form.submit();">
</form>

For the same page, you can always use METHOD=get and submit to the same page.
To retrieve it, you do the same thing.

no it's not, since javascript is executed on the client, while all jsp code is processed on the server. That is why you have to submit the page so the server gets the values.
