<p>I´ve been testing using 1 Apache Http Server + 2 instances in cluster of tomcat7 and the "weld-jsf-numberguess"(weld-2.0.3.Final) modified to use conversation scope.</p>
<p>The apache using:<br/>
<Proxy balancer://testcluster stickysession=JSESSIONID></p>
<p>BalancerMember ajp://127.0.0.1:8019 route=node1 loadfactor=1<br/>
BalancerMember ajp://127.0.0.1:8029 route=node2 loadfactor=1 <br/>
</Proxy></p>
<p>Modify the class org.jboss.weld.examples.numberguess.Game to @ConversationScoped and add the method:</p>
<p>@Inject<br/>
Conversation conversation;</p>
<p>//Atribute used to test the state of conversation<br/>
private Integer testValue = 0 ;</p>
<p>public void beginConversation()<br/>
{<br/>
if (conversation.isTransient())</p>
{
conversation.begin();
}
<p>}</p>
<p> public void check() {</p>
<p> testValue = testValue + 1;</p>
<p> if (guess > number) </p>
{
biggest = guess - 1;
}
<p> else if (guess < number) </p>
{
smallest = guess + 1;
}
<p> else if (guess == number) </p>
{
FacesContext.getCurrentInstance().addMessage(null, new FacesMessage("Correct!"));
}
<p> remainingGuesses--;<br/>
}</p>
<p>Modify the home.xhtml add the code :</p>
<p><f:metadata><br/>
<f:event type="preRenderView" listener="#</p>
{game.beginConversation}
<p>"/><br/>
</f:metadata></p>
<p>and </p>
<p>//Just for to see the state of this attribute being saved by the conversation<br/>
<h:outputText id="testValue" value="#</p>
{game.testValue}
<p>" /></p>
<p>// The scenario:</p>
<p>1- Open the project and one instance of the cluster will be called.<br/>
2- Update the values of the testValue by clicking some times the button "Guess"<br/>
3- Stop instance of the cluster that is being called until here.<br/>
4- click the button "Guess"</p>
<p>5- Result >> the value of "testValue" fall back to the firt value "1". <br/>
That leads me to think that: the only time the conversation is replicated is when is created.</p></div>
