How to generate a non-secured response to a secured request?

In other words - how to avoid rampart being executed in the OutFlow of a particular service.

1. Add a new phase [NoSecurity] in global axis2.xml under OutFlow - just before the Security phase

<phaseOrder type="OutFlow">
        <phase name="soapmonitorPhase"/>
        <phase name="OperationOutPhase"/>
        <phase name="RMPhase"/>
        <phase name="PolicyDetermination"/>
        <phase name="MessageOut"/>
        <phase name="NoSecurity"/>
        <phase name="Security"/>
</phaseOrder>

2. Create a module [say, nosecuity] with handler having the following logic.

public InvocationResponse invoke(MessageContext msgContext) throws AxisFault {
    msgContext.setCurrentHandlerIndex(msgContext.getCurrentHandlerIndex() + 2);
    return InvocationResponse.CONTINUE;
}

You can download the eclipse project for this module from here.

3. Engage this module to the service you want to remove security frome OutFlow.

<module ref="nosecurity" />
