Sr. Java/J2EE developer

ENVIRONMENT: WebLogic 11g, Spring 2.5 MVC, Eclipse 3.4, SQL Server 2010, XML, JSP, HTML, JUnit 3.8.1, UNIX, Hibernate 3.0, JavaScript, Windows XP.

Responsibilities:

• Used UML to design various data models including class diagrams, dataflow diagrams, workflow diagrams, sequence diagrams and interaction diagrams.
• Implemented various J2EE Design patterns like Business delegate, Data Access Object, MVC.
• Used Struts 2.1 MVC framework for previous implementations.
• Implemented the Action classes in Struts2 and configured the Application-resources-properties file for displaying the input validation error messages.
• Created Action-validation.xml file for validating the input actions for form validation and modified struts.xml file.
• Used Spring MVC 2.5.6 framework to develop the web services for the application. Configured Dispatcher Servlet in web.xml.
• Mapped the controller (abstract) to a URL in .servlet.xml file. The data was propagated into the JSP through the model and view object from the controller.
• Developed interfaces and bean implementations for the same for propagating data on the JSPs.
• Wrote Spring configuration files for the beans defined and properties to be injected into them using spring's Dependency Injection.
• Developed Hibernate.cfg.xml to define the connection pooling which was being provided by Hibernate, did mapping for the POJOs in the application for which tables existed in the back end DB and developed corresponding .hbm files.
• Configured JMS Template, connection factory in spring-jms.xml.
• Used spring’s AOP to implement logging and getting data source objects. Log4j was used to implement logging.
• Developed a stored procedure for achieving data validation. Developed configuration files corresponding to beans mapped and backend database tables.
• Eclipse 3.4 was used as the application development environment on windows XP operating system.
• Deployed the application on BEA WebLogic 11g Server. Used SQL Server 2010 as data base for creating stored procedures.
