· Developed application based on SOA by integrating the Spring MVC application managed beans with JSF-Prime Faces view for building the application.· Build web application using JSF Prime Faces by assembling reusable UI components in a page and wiring the client generated events to server-side event handlers.· Developed reusable components using JSF Prime Faces through XML file view templates.· Extensively used Java server Faces (JSF) Navigation rules and JSF tags for enhanced user Interface.· Injected the JSF Managed beans using Spring-managed beans by extending the Spring Bean Auto Wiring support to achieve the Dependency Injection.· Used Spring Bean Faces Resolver i.e., Spring Resolver to integrate the Spring MVC application with the JSF pages.· Managed Beans for handling JSF pages and include logic for processing of the data on the page.· Used Spring JPA to perform CRUD Operations and persist the data to the database.· Developed the code for asynchronous update to web page using JavaScript and Ajax.· Used XSL, XSLT pre-processors to transform, navigate and format XML documents.· Used Connection Pooling to get JDBC connection and access database procedures.· Extensive use of Collection Framework features like Map, Object, List to retrieve the data from Web Service, manipulate the data to incorporate Business Logic and save the data to Oracle database.

· Designed and developed web interfaces and business logic using Jakarta Struts Framework (MVC architecture).· Extensively used CSS and Bootstrap for styling the HTML elements.· Developed dynamic web pages using HTML5, CSS3, Bootstrap, Less, CSS3 (SASS) and AJAX.· Development of Action Forms, Action Servlets, Action and Validating Action Forms in Struts framework.· Implemented MVC pattern by using the Struts with controller servlet.
