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>
