Appreciate your kindness Ulf Dittmer and sorry for the very late reply! I know,the Servlet API along with JSP and JDBC enough to handle everything .But I would like to learn some frameworks and decided to use
Struts (used to implement the MVC Architecture),Spring(increasing development productivity),Hibernate/JPA (db) and extjs(extend the user friendliness)for the project .Like to know your ideas .Thanks for your help!
