Beyond PSD2 for a Better Open Banking Expereince

PSD2 is acting as a catalyst in the digital transformation happening in the Banking industry. While meeting the compliance requirements of PSD2, financial institutes are excited to make use of the new business models and opportunities opened by this laid foundation. More the customers and partners we can reach, more the business activities and more the revenue. Making the banking functions more accessible and reactive will be a key enabler to provide a seamless experience to these parties, including internal banking staff whom directly affects the business efficiency.
IAM plays a critical role in improving business accessibility without compromising the system boundaries. PSD2 mandates strong customer authentication(SCA), setting the bar high for user authenticity, while keeping few exemptions, not to bother payment services user(PSU) with SCA for every little transactions. While adhering to this policy will make an institute PSD2 complaint, if they can react fast to the fraud rates…

Writing Axis2 Custom Deployers - hot deployment - WSO2 Carbon Products

Custom deployers is a concept introduced to Axis2 to increase it's flexibility and enhance the dynamic nature. With this article on Axis2 Custom Deployers, it's originator himself explains it's background and procedure in details. With this post, I'll just share the steps I followed in using this feature.
  • Following is the basic structure of a custom deployer. There needs to be a class that has implemented 'org.apache.axis2.deployment.Deployer' interface and a component.xml file that carries some required properties for the deployer.
  • Following is the basic structure of a CustomDeployer class.
public class CustomDeployer extends AbstractDeployer {

    private static Log log = LogFactory.getLog(CustomDeployer.class);
    private File userMgtConfigFile;
    private RealmConfigXMLProcessor realmConfigXMLProcessor = new RealmConfigXMLProcessor();

    public void init(ConfigurationContext configurationContext) {
        // Here goes all the initialization code.
    }

    public void deploy(DeploymentFileData deploymentFileData) throws DeploymentException {
        File file = deploymentFileData.getFile();
        // Here goes the processing code need to process the file
    }

    public void setDirectory(String s) {
        // if we need to know the subdirectory that the deployer has registered
    }

    public void setExtension(String s) {
        //extension of the file that the deployer has registered
    }
}
When there is a file addition in the subdirectory that we are interested in (file extension that the deployer has registered with) 'deploy' method is called. When a file is deleted 'undeploy' method is called. When a modification is done both the methods will be called accordingly. Directory and extension of the files to be deployed can be set by the relevant methods.
  • Following is a sample component.xml file written for a WSO2 Carbon product.
<component xmlns="http://products.wso2.org/carbon">
    <deployers>
        <deployer>
            <directory>userstore</directory>
            <extension>xml</extension>
            <class>org.wso2.carbon.identity.user.store.configuration.deployer.UserStoreConfigurationDeployer</class>
        </deployer>
    </deployers>
</component>
  • Finally in the pom.xml(of Maven module) we should define the deployer as follows,
<Axis2Deployer>CustomDeployer</Axis2Deployer> 
  •  We are done now. Finally one more thing worth to note is, we can enable hot update by setting 'true' for the parameter 'hotupdate' in axis2.xml. With this if we add a file of the given extension in the directory, the file will be get deployed at the moment itself.

    Cheers!
