Call a Servlet from a jsp

Can we call a servlet from a JSP, come back and display the response data we get from the servlet in the same JSP? Is it possible to do that?

Basically, I have a pop up in which the user gives some input. I pass this to the servlet and the servlet gives me an acknowledgement number. I would like to display this acknowledgement number in the same pop up.

In the meantime, during which the servlet gives the response, I can display an hour glass in the pop up. Is this possible?

Someone please help me with an example please.


Option 1 You can submit form in your popup jsp and then forward to the same JSP from servlet. Option 2 You can use ajax and call servlet and then send response (e.g. JSON) back from servlet and update what you need using javascript, jquery.

Yes we can call servlet from jsp.

To call servlet from jsp use,

<form action="../Your_servlet_name_in_web.xml_file">

And to call JSP from servlet use,
