do I make my service startup with the rest of the application, rather than
lazily?</h3>
+
+<p>Tapestry services are designed to be <em>lazy</em>; they are only fully
realized when needed: when the first method on the service interface is
invoked.</p>
+
+<p>Sometimes a service does extra work that is desirable at application
startup: examples may be registering message handlers with a JMS
implementation, or setting up indexing. Since the service's constructor (or <a
shape="rect" class="external-link"
href="http://tapestry.apache.org/current/apidocs/org/apache/tapestry5/ioc/annotations/PostInjection.html";>@PostInjection</a>
methods) are not invoked until the service is realized.</p>
+
+<p>The solution is the <a shape="rect" class="external-link"
href="http://tapestry.apache.org/current/apidocs/org/apache/tapestry5/ioc/annotations/EagerLoad.html";>@EagerLoad</a>
annotation; service implementation classes marked with this annotation are
loaded when the Registry is first startup, rather than lazily.</p>
