Apache Rampart not working with JBoss 6 - web-services

Question

I'm using Axis 2 1.5.4 to deploy web services on JBoss 6.0.0 and using Apache Rampart 1.5.2 to implement UserName Token security for the web services. My services gets deployed successfully and I can see the web services policy in the WSDL.
But when I launch the web service through SOAP UI , it doesn't ask for any security information and directly calls my web service method and does not even invoke the PasswordCallBackHandler class. The same service and security works with Tomcat but not with JBoss.
Sample from my WSDL:
<?xml version="1.0" encoding="UTF-8" ?>
- <wsdl:definitions xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:ns1="http://org.apache.axis2/xsd" xmlns:ns="http://ws.apache.org/axis2" xmlns:wsaw="http://www.w3.org/2006/05/addressing/wsdl" xmlns:http="http://schemas.xmlsoap.org/wsdl/http/" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:mime="http://schemas.xmlsoap.org/wsdl/mime/" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:soap12="http://schemas.xmlsoap.org/wsdl/soap12/" targetNamespace="http://ws.apache.org/axis2">
- <wsp:Policy xmlns:wsp="http://schemas.xmlsoap.org/ws/2004/09/policy" xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd" wsu:Id="UsernameToken">
- <wsp:ExactlyOne>
- <wsp:All>
- <sp:SupportingTokens xmlns:sp="http://schemas.xmlsoap.org/ws/2005/07/securitypolicy">
- <wsp:Policy>
<sp:UsernameToken sp:IncludeToken="http://schemas.xmlsoap.org/ws/2005/07/securitypolicy/IncludeToken/AlwaysToRecipient" />
</wsp:Policy>
</sp:SupportingTokens>
</wsp:All>
</wsp:ExactlyOne>
</wsp:Policy>
Below is my services.xml:
<service>
<module ref="rampart" />
<parameter name="ServiceClass" locked="false">SimpleService</parameter>
<operation name="echo">
<messageReceiver class="org.apache.axis2.rpc.receivers.RPCMessageReceiver"/>
</operation>
<wsp:Policy wsu:Id="UsernameToken" xmlns:wsu=
"http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd"
xmlns:wsp="http://schemas.xmlsoap.org/ws/2004/09/policy">
<wsp:ExactlyOne>
<wsp:All>
<sp:SupportingTokens
xmlns:sp="http://schemas.xmlsoap.org/ws/2005/07/securitypolicy">
<wsp:Policy>
<sp:UsernameToken sp:IncludeToken="http://schemas.xmlsoap.org/ws/2005/07/securitypolicy/IncludeToken/AlwaysToRecipient"/>
</wsp:Policy>
</sp:SupportingTokens>
<ramp:RampartConfig xmlns:ramp="http://ws.apache.org/rampart/policy">
<ramp:passwordCallbackClass>MyHandler</ramp:passwordCallbackClass>
</ramp:RampartConfig>
</wsp:All>
</wsp:ExactlyOne>
</wsp:Policy>
</service>
Am I missing some configurations from JBoss? Please help me in resolving the issue as I am totally stuck.
