<div class="jive-rendered-content"><p>Hi all,</p><p>I need a little help in understanding how JBoss Invokers work. I am not sure I understood </p><p>whatever I've read, so please let me know when I am wrong.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>I use JBoss 4.2.3 in my project and have JAX-WS webservices deployed in it (Consider one of </p><p>these as WebService A). These WebServices are POJO based ones and form WebService clients to </p><p>EJB based WebServices that my vendor offers (Consider one of these vendor WebServices V). </p><p>Hence, I have WebService to WebService calls within same JVM, i.e., the invocation flow is:<br/>External system -> A -> V -> Database</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>When a new request comes in for A, where does the invoker come in ? I thought that the </p><p>internal WebService call from A to V uses the invoker as V is an EJB based WebService and I </p><p>have configured "Standard Stateless SessionBean" to use "stateless-rmi-invoker" which inturn </p><p>uses "jboss:service=invoker,type=pooled" (That was what I've configured in standardjboss.xml). </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>My jboss-service.xml for pooled invoker is: </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><pre class="jive-pre"><code class="jive-code jive-xml">

</code></pre><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>However, when I take a look at the threaddump (via the JMX console jboss.system:type=ServerInfo listThreadDump()), I don't find any PooledInvokerThread instances in the thread dump. Does that mean that I am not using pooled invokers ?</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>I am trying to see if there are any areas where I can tweak some parameters to improve the number of requests that JBoss can handle for my application.
