<P>This package has the timer related function.

<H3>Required jars</H3>
<P>The jar commonj-twm.jar contains these interfaces.

<H2>Timers</H2>
<P>Both Java<SUP>TM</SUP> 2 Standard Edition 1.3 (J2SE) and Java<SUP>TM</SUP>
2 Enterprise Edition 1.4 (J2EE) provide a timer mechanism. The J2SE
timer mechanism does not utilize Java interfaces and is very
difficult to manage and extend from a J2EE perspective. The EJB 2.1
Timer service does not address transient timers and does not provide
a way for Servlets to create persistent timers.</P>
<P>This package could form the basis of a generic timer service that
is used by J2SE, and J2EE (servlets and EJBs). The timers created
with this service are transient and have application scope (all
components in an application can look it up in JNDI).
