3.9 Applets: TextApplet.jsp

This  example  demonstrates  how  to  call  on  the  services  of  a  Mathematica powered  web  site  from  an  applet.  This

shows a combination of client and server programming. The section involves some programming in Java.

If  you  installed  webMathematica  as  described  

above

,  you  should  be  able  to  connect  to  this  MSP  via

http://localhost:8080/webMathematica/Examples/TextApplet.jsp.  (You  may  have  some  other  URL  for  accessing

your  server.)  The  source  for  this  page  is  in  webMathematica/Examples/TextApplet.jsp  and  web 

Mathematica/WEB INF/src/ExampleApplets/TextApplet.java.

First, here is the JSP source.

<%@ page language="java"  %>

<%@ taglib uri="/webMathematica taglib" prefix="msp" %>

Here is an applet that gets a result from Mathematica:

If[ MSPValueQ[ $$Compute],

MSPReturn[ "Date[] returns " <> ToString[ Date[]], 

"text/plain"]]

code="TextApplet" 
archive = 
" $WebApplication <> 
"/Resources/applets/MSPExamples.jar""  
width="400"
height="30" >

Hitting refresh will cause the page to update.

Here is the source for the applet TextApplet.java.
