<div class="jive-rendered-content"><p>   I have read the docs about integrating JBPM5.4 on Tomcat, and tried to go throuth the steps.It seemed that a JMS implementation(such as HornetQ) should be needed, but when I tried to install HornetQ(2.3.0.Final) on Tomcat6, error messages appeared.  </p><p>   I tried to follow the source code of org.springframework.beans.factory.xml.BeanDefinitionParserDelegate.java and org.springframework.beans.factory.xml.DefaultNamespaceHandlerResolver.java, and it seemed that spring framework had to find a class that implements the interface NamespaceHandler, and should have been stored in a file(such as META-INF/spring.handlers). And then I followed the source code of hornetq-2.3.0.Final, and didn't find any class that had implemented the interface of NamespaceHandler.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>   Here are my questions:</p><p>   1. Must HornetQ(or some other JMS implementation) be installed? </p><p>   2. If HornetQ must be installed, where is the class that implements the interface NamespaceHandler ? or is there any documentation that describes the steps of integrating HornetQ with Tomcat?</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>  I posted a thread in the forum of HornetQ, but no one responded. So I came here for help, can anybody give some light? thanks a lot!</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p> The error messages are listed as below:</p><p>Exception sending
