The above contribution lost a few (rather critical) bits of XML. Hopefully i will do a little better (though I am not all all sure)


*JBoss Messaging Null Persistence Service*  

*Purpose:* To disable the Database Persistence Policy and introducing Null Persistence Service.

*Step 1:* we have to delete the existing {color:green}\server\default\deploy\messaging\hsqldb-persistence-service.xml{color}.

*Step 2:* delete the following *messaging* security policy from the {color:green}\server\default\deploy\messaging\messaging-jboss-beans.xml{color} file

{code:xml}
   <!-- messaging application-policy definition -->
   <application-policy xmlns="urn:jboss:security-beans:1.0" name="messaging">
      <authentication>
         <login-module code="org.jboss.security.auth.spi.DatabaseServerLoginModule" flag="required">
            <module-option name="unauthenticatedIdentity">guest</module-option>
            <module-option name="dsJndiName">java:/DefaultDS</module-option>
            <module-option name="principalsQuery">SELECT PASSWD FROM JBM_USER WHERE USER_ID=?</module-option>
            <module-option name="rolesQuery">SELECT ROLE_ID, 'Roles' FROM JBM_ROLE WHERE USER_ID=?</module-option>
         </login-module>
      </authentication>
   </application-policy>
{code}

*Step 3:* Include the messaging policy in the {color:green}\server\default\conf\login-config.xml{color} file as the follows,

{code:xml}
      <!-- A template configuration for messaging. This
defaults to the UsersRolesLoginModule the same as other and should be
changed to a stronger authentication mechanism as required.
-->
<application-policy name="messaging">
 <authentication>
   <login-module code="org.jboss.security.auth.spi.UsersRolesLoginModule" flag="required">
      <module-option name = "unauthenticatedIdentity">guest</module-option>
      <module-option name="usersProperties">props/messaging-users.properties</module-option>
      <module-option name="rolesProperties">props/messaging-roles.properties</module-option>
   </login-module>
  </authentication>
</application-policy>
{code}

And also place the following properties files in the directory {color:green}\server\default\conf\props{color}

{code}
1. messaging-users.properties
------------------------------
#
# user=password
#
guest=guest

2. messaging-roles.properties
-------------------------------
#
# user=role1,role2,...
#
guest=guest
{code}

*Step 4:* Place the null-persistence-service.xml file with the following contents under the directory {color:green}\server\default\deploy\messaging{color}

{code:xml}
<?xml version="1.0" encoding="UTF-8"?>

<!--
     Null persistence config.
     
     Use this if you don't actually want to persist anything
     
     $Id$
 -->

<server>

   <!-- Persistence Manager MBean configuration
       ======================================== -->

   <mbean code="org.jboss.messaging.core.jmx.NullPersistenceManagerService"
      name="jboss.messaging:service=PersistenceManager"
      xmbean-dd="xmdesc/NullPersistenceManager-xmbean.xml"/>
     
   <!-- Messaging Post Office MBean configuration
        ========================================= -->

   <mbean code="org.jboss.messaging.core.jmx.MessagingPostOfficeService"
      name="jboss.messaging:service=PostOffice"
      xmbean-dd="xmdesc/MessagingPostOffice-xmbean.xml">

      <depends optional-attribute-name="ServerPeer">jboss.messaging:service=ServerPeer</depends>
      <depends optional-attribute-name="TransactionManager">jboss:service=TransactionManager</depends>
      
      <!-- The name of the post office -->

      <attribute name="PostOfficeName">JMS post office</attribute>
     
      <!-- This post office is clustered. If you don't want a clustered post office then set to false -->

      <attribute name="Clustered">false</attribute>
 
   </mbean>

   <!-- Messaging JMS User Manager MBean config
        ======================================= -->

   <mbean code="org.jboss.jms.server.plugin.JDBCJMSUserManagerService"
      name="jboss.messaging:service=JMSUserManager"
      xmbean-dd="xmdesc/JMSUserManager-xmbean.xml">
        <depends optional-attribute-name="TransactionManager">jboss:service=TransactionManager</depends> 
   </mbean>

</server>
