In this example, one evaluation tests the variable $$button. If it has a value from activating one of the buttons in

the form, this is used to specify a return format type and passed to a function, GeneralContent. The Mathemat 

ica code  for this  function  is placed  into a separate  package  to be loaded  when  the variable  is set. GeneralCon 

tent calls a function that creates a very simple notebook, MakeNotebook. MakeNotebook generates a notebook

using  the  Mathematica  Notebook  API  and  the  J/Link  function  UseFrontEnd.  In  a  real  life  situation  a  more

interesting notebook would probably be generated. 

MSPReturn

 returns the representation  of the notebook to the

server  with  the  content  type.  This  is  then  returned  to  the  browser,  which,  if  suitably  configured,  will  deploy  the

necessary helper application.

In  a  more  advanced  example,  the  dynamically  generated  notebook  would  probably  use  information  sent  with  the

request from the client. 

If you wish to return special content and also set a filename to be used with this content, then you may wish to use

the three argument form of 

MSPReturn

. This is described in the 

MSP Function Reference

 section. 

Another way to set the content returned from an MSP script is to use 

MSPPageOptions

. The topic of returning

general content is discussed later.
