Engaging modules dynamically

Hi,

I am embedding Axis2 in an application and trying to engage Rampart
dynamically using the code below,

AxisService axisService = new AxisService();

axisService.setName(uri);
axisService.setClientSide(false);
axisService.setClassLoader(classLoader);
axisService.setEndpointURL(uri);

Parameter interfaceParameter =
    new Parameter(Constants.SERVICE_CLASS, serviceClass);
axisService.addParameter(interfaceParameter);

setMessageReceivers(wire, axisService);

AxisModule rampart = new AxisModule("rampart");
axisService.engageModule(rampart);

for (Element policyDefinition : pwsd.getPolicyDefinitions()) {
    axisService.applyPolicy(policyBuilder.buildPolicy(policyDefinition));
}

configurationContext.getAxisConfiguration().addService(axisService);

However, when I try to engage Rampart, I get the following exception,
any pointers would be highly appreciated.

Caused by: java.lang.NullPointerException

Many thanks

Hi,

I have managed to fix it by engaging the module after adding the
service to the configuration context. However, I am not sure whether
the module is being engaged succesfully. I have the following policy
applied to the service, however, the client is able to invoke the
service without any security credentials.

<wsp:Policy xmlns:wsp="http://schemas.xmlsoap.org/ws/2004/09/policy"

xmlns:sp="http://schemas.xmlsoap.org/ws/2005/07/securitypolicy">
    <sp:UsernameToken>
        <wsp:Policy>
            <sp:WssUsernameToken11/>
         </wsp:Policy>
     </sp:UsernameToken>
</wsp:Policy>

Ta
Meeraj
