Responsibilities:

• Provides users a web interface to create a particular order with user’s input into order fields, field validation is done both in client and backend inventory using CoreJava/HTML/JavaScript/JSP
• Retrofits lengthy JSP by dividing functionality among objects based on MVC to Struts framework.
• Implement a shopping cart which can hold multiple orders with different types using Java Bean, session object, cookies, JSP
• Cron jobs which periodically trigger processes to send XML requests through FTP to get automatic email logs from another system.
• Cron jobs which periodically trigger processes to pick order of specific type in queue and send it to inventory
• After getting order from shopping cart, save order to XML and populate Oracle DB fields using SQL/SP/JDBC
