                    Web service calls to invoke secured services during mediation.

                <p>
                    In this sample, the Callout mediator does the service invocation to the Secured service
                    SecureStockQuoteService by encrypting the client request according to the defined policy.
                    And then received encrypted message is decrypted and after removing the wsse:Security header,
                    the message is sent back to the client using the send mediator.

                    Callout Mediator is configured to enable WS-Security as per the policy specified by 'policy_3.xml'.
                </p>
                <p>
                    Invoke the client as follows.
