jsp query: Viewing the processing status in same page

[kiranmayi_p1]

hi friends

I want to know how to get a value from a form, process data from backend using this value, and display results in the same form. That means, I want to submit the form to itself and write jdbc in js function and alert the results.How is it possible. Kindly suggest

Kiranmayi,

If you want to use javascript to pass data to server for further processing/storing data, you may need to take help of AJAX. It is what exactly AJAX does.

But if you want to use pure JSP technology, then it is possible by submitting the page to server and getting the response back. Sample code may look like this -

<%
String name = request.getParameter("name");
if(name!=null or name!="")
out.writeln("Welcome : " +name);
%>
<form name=test action=selftest.jsp>
<input type=text name="name">
</form>

Thanks,
Krishna
