I am using the below code for the proxy authentication

                HttpTransportProperties.Authenticator basicAuthentication = new HttpTransportProperties.Authenticator();
            HttpTransportProperties.ProxyProperties proxyProperties = new HttpTransportProperties.ProxyProperties();
            _operationClient.getOptions().setProperty(org.apache.axis2.transport.http.HTTPConstants.AUTHENTICATE,basicAuthentication);
            proxyProperties.setProxyName("proxy address");
            proxyProperties.setProxyPort(port);
            proxyProperties.setUserName("");
            proxyProperties.setPassWord("");
 _serviceClient.getOptions().setProperty(HTTPConstants.PROXY, proxyProperties);
    _getServiceClient().getOptions().setProperty( HTTPConstants.CHUNKED, "false" );

Thanks for the help in advance
