Question:
How to transfer a file from the server side to a client browser with a JSP or a servlet?.

You can include the file in the JSP using the <jsp:include> tag with the file type and location parameters.

The simplest solution is to use the forward() method of the RequestDispatcher class.
RequestDispatcher rd = request.getRequestDispatcher(url); // url to the file
rd.forward(request, response);

Uploading a file to a client browser is not allowed by Java security model

You can use the <jsp:file> tag for this task with proper parameters of the file type and location.

This is a multiple-step task.
You will need to set the MIME content type and length of the file in the response object.
Then, you will need to read a file and write its data to the respose output stream
