     <h1>StatefulContainer Configuration

         <div style="float: right; position: relative; bottom: -10px; ">
             <a onclick="javascript:gpshare()" class="gp-share sprite" title="Share on Google+">share [gp]</a>

         </div>
     </h1>
 </div>

 <p>A StatefulContainer can be declared via xml in the <code>&lt;tomee-home&gt;/conf/tomee.xml</code> file or in a <code>WEB-INF/resources.xml</code> file using a declaration like the following.  All properties in the element body are optional.</p>

 <pre><code>&lt;Container id="myStatefulContainer" type="STATEFUL"&gt;
     accessTimeout = 30 seconds
     bulkPassivate = 100
     cache = org.apache.openejb.core.stateful.SimpleCache
     capacity = 1000
     frequency = 60
     passivator = org.apache.openejb.core.stateful.SimplePassivater
     timeOut = 20
 &lt;/Container&gt;
 </code></pre>

 <p>Alternatively, a StatefulContainer can be declared via properties in the <code>&lt;tomee-home&gt;/conf/system.properties</code> file or via Java VirtualMachine <code>-D</code> properties.  The properties can also be used when embedding TomEE via the <code>javax.ejb.embeddable.EJBContainer</code> API or <code>InitialContext</code></p>

 <pre><code>myStatefulContainer = new://Container?type=STATEFUL
 myStatefulContainer.accessTimeout = 30 seconds
 myStatefulContainer.bulkPassivate = 100
 myStatefulContainer.cache = org.apache.openejb.core.stateful.SimpleCache
 myStatefulContainer.capacity = 1000
 myStatefulContainer.frequency = 60
 myStatefulContainer.passivator = org.apache.openejb.core.stateful.SimplePassivater
 myStatefulContainer.timeOut = 20
 </code></pre>

 <p>Properties and xml can be mixed.  Properties will override the xml allowing for easy configuration change without the need for ${} style variable substitution.  Properties are not case sensitive.  If a property is specified that is not supported by the declared StatefulContainer a warning will be logged.  If a StatefulContainer is needed by the application and one is not declared, TomEE will create one dynamically using default settings.  Multiple StatefulContainer declarations are allowed.</p>

 <p><a name="accessTimeout"></a></p>

 <h2>accessTimeout</h2>

 <p>Specifies the maximum time an invocation could wait for the
 <code>@Stateful</code> bean instance to become available before giving up.</p>

 <p>After the timeout is reached a <code>javax.ejb.ConcurrentAccessTimeoutException</code>
 will be thrown.</p>

 <p>Usable time units: nanoseconds, microsecons, milliseconds,
 seconds, minutes, hours, days.  Or any combination such as
 "1 hour and 27 minutes and 10 seconds"</p>

 <p>Any usage of the <code>javax.ejb.AccessTimeout</code> annotation will
 override this setting for the bean or method where the
 annotation is used.</p>

 <p><a name="passivator"></a></p>

 <h2>passivator</h2>

 <p>The passivator is responsible for writing beans to disk
 at passivation time. Different passivators can be used
 by setting this property to the fully qualified class name
 of the <code>PassivationStrategy</code> implementation. The passivator
 is not responsible for invoking any callbacks or other
 processing, its only responsibly is to write the bean state
 to disk.</p>

 <p>Known implementations:</p>

 <ul>
 <li>org.apache.openejb.core.stateful.RAFPassivater</li>
 <li>org.apache.openejb.core.stateful.SimplePassivater</li>
 </ul>

 <p><a name="timeOut"></a></p>

 <h2>timeOut</h2>

 <p>Specifies the time a bean can be idle before it is removed by the container.</p>

 <p>This value is measured in minutes. A value of 5 would
 result in a time-out of 5 minutes between invocations.
 A value of -1 would mean no timeout.
 A value of 0 would mean a bean can be immediately removed by the container.</p>

 <p>Any usage of the <code>javax.ejb.StatefulTimeout</code> annotation will
 override this setting for the bean where the annotation is used.</p>

	<h1>StatefulContainer Configuration

	</div>

	<p>A StatefulContainer can be declared via xml in the <code><tomee-home>/conf/tomee.xml</code> file or in a <code>WEB-INF/resources.xml</code> file using a declaration like the following. All properties in the element body are optional.</p>

	<pre><code><Container id="myStatefulContainer" type="STATEFUL">
	accessTimeout = 30 seconds
	bulkPassivate = 100
	cache = org.apache.openejb.core.stateful.SimpleCache
	capacity = 1000
	frequency = 60
	passivator = org.apache.openejb.core.stateful.SimplePassivater
	timeOut = 20
	</Container>
	</code></pre>

	<p>Alternatively, a StatefulContainer can be declared via properties in the <code><tomee-home>/conf/system.properties</code> file or via Java VirtualMachine <code>-D</code> properties. The properties can also be used when embedding TomEE via the <code>javax.ejb.embeddable.EJBContainer</code> API or <code>InitialContext</code></p>

	<pre><code>myStatefulContainer = new://Container?type=STATEFUL
	myStatefulContainer.accessTimeout = 30 seconds
	myStatefulContainer.bulkPassivate = 100
	myStatefulContainer.cache = org.apache.openejb.core.stateful.SimpleCache
	myStatefulContainer.capacity = 1000
	myStatefulContainer.frequency = 60
	myStatefulContainer.passivator = org.apache.openejb.core.stateful.SimplePassivater
	myStatefulContainer.timeOut = 20
	</code></pre>

	<p>Properties and xml can be mixed. Properties will override the xml allowing for easy configuration change without the need for ${} style variable substitution. Properties are not case sensitive. If a property is specified that is not supported by the declared StatefulContainer a warning will be logged. If a StatefulContainer is needed by the application and one is not declared, TomEE will create one dynamically using default settings. Multiple StatefulContainer declarations are allowed.</p>

	<p><a name="accessTimeout"></a></p>

	<h2>accessTimeout</h2>

	<p>Specifies the maximum time an invocation could wait for the
	<code>@Stateful</code> bean instance to become available before giving up.</p>

	<p>After the timeout is reached a <code>javax.ejb.ConcurrentAccessTimeoutException</code>
	will be thrown.</p>

	<p>Usable time units: nanoseconds, microsecons, milliseconds,
	seconds, minutes, hours, days. Or any combination such as
	"1 hour and 27 minutes and 10 seconds"</p>

	<p>Any usage of the <code>javax.ejb.AccessTimeout</code> annotation will
	override this setting for the bean or method where the
	annotation is used.</p>

	<p><a name="passivator"></a></p>

	<h2>passivator</h2>

	<p>The passivator is responsible for writing beans to disk
	at passivation time. Different passivators can be used
	by setting this property to the fully qualified class name
	of the <code>PassivationStrategy</code> implementation. The passivator
	is not responsible for invoking any callbacks or other
	processing, its only responsibly is to write the bean state
	to disk.</p>

	<p>Known implementations:</p>

	<ul>
	<li>org.apache.openejb.core.stateful.RAFPassivater</li>
	<li>org.apache.openejb.core.stateful.SimplePassivater</li>
	</ul>

	<p><a name="timeOut"></a></p>

	<h2>timeOut</h2>

	<p>Specifies the time a bean can be idle before it is removed by the container.</p>

	<p>This value is measured in minutes. A value of 5 would
	result in a time-out of 5 minutes between invocations.
	A value of -1 would mean no timeout.
	A value of 0 would mean a bean can be immediately removed by the container.</p>

	<p>Any usage of the <code>javax.ejb.StatefulTimeout</code> annotation will
	override this setting for the bean where the annotation is used.</p>
