RE: How to trigger events from tomcat?
It seems the best way to do it is in a process or a thread, running
aside the regular web-application. This indeed uses an infinite loop to
check on times. You should be able to set this process as a low-priority
process, so it doesn't consume too much processor time.
I don't know if there is anything like a Timer in Java which you could
use, where it triggers on a timer interrupt. This should make it even
more lightweight.

Sjoerd

Subject: How to trigger events from tomcat?
hi,
I am developing a web based appointment sheduler. the data is stored in
xml format. i am using tomcat/jsp/servlet
for example if i added a new appointment , the program will ask for a
reminder time. I am giving 08/08/2003 10:30
so at 08/08/2003 10:30 an email should be sent to me saying that u have
an appointment.
how can i trigger for appointments. ie some method should be ther to
check if the appointment time is due on each second. Can i put an
infinite loop some how?
thanks n regds

JSP 2.0 XML Syntax Problem

RE: Tomcat 5 and well-formed XHTML
Posted by Sjoerd van Leent <sv...@wanadoo.nl>.
OK I'm baffeled, I did use:
<jsp:directive.page language="java"
contentType="text/html ; charset=ISO-8859-1"
pageEncoding="ISO-8859-1" />
But reading the example it says that the ";" sign between text/html and
charset must contain no spaces at the front, so you'll get:
<jsp:directive.page language="java"
contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1" />
Why always such a stupidity?
