Invoke Secured web service in wso2esb

Question

I have created a web service in WSO2 ESB. The security implements that only a particular user-role can access it.

Now, when I hit this service useing SOAP-UI, by providing username, password, password type, I m able to hit the service.

Now, I want to create a StandAlone Java Project that can access this SECURED WEB SERVICE.

I m trying to implement apache-rampart for this purpose, but the information I have is scattered.

Can anyone please help me on how to access this secured service.

Thanks and Regards.

Access to a secure web service in this way, I presume you use UT scenario:

String trustStore = null;  
ConfigurationContext ctx = null;
String policyFilePath = "[file_system_path]/secure_sample_policy.xml";

trustStore = "[file_system_path]/wso2carbon.jks";  
System.setProperty("javax.net.ssl.trustStore",trustStore);  
System.setProperty("javax.net.ssl.trustStorePassword","pass_store");  

ctx = ConfigurationContextFactory.createConfigurationContextFromFileSystem(null,
        null);
this.stub = new ProxyStub(ctx);
stub._getServiceClient().engageModule("rampart");
stub._getServiceClient().engageModule("addressing");

Options options = this.stub._getServiceClient().getOptions();
options.setUserName("user");
        options.setPassword("pass");

options.setProperty(RampartMessageData.KEY_RAMPART_POLICY, loadPolicy(policyFilePath));
this.stub._getServiceClient().setOptions(options);

the method loadPolicy:

private static Policy loadPolicy(String xmlPath) throws Exception {
    StAXOMBuilder builder = new StAXOMBuilder(xmlPath);
    return PolicyEngine.getPolicy(builder.getDocumentElement());
}

And an example policy file:

<?xml version="1.0" encoding="UTF-8"?>
