Summarize the Complete J2EE Applications

What this episode covers

A Struts/JSP Application Creating Simple Login Procedure for web application using struts. The steps are to create a struts page flow, edit the jsp pages, run with the embedded j2ee container. Create a new application. Create a struts based page flow for the application. This application starts with a login page that activates a validation routine that can route to the applications menu or to a failure notice. Create struts form bean to pass parameter to the struts action. Then connect the struts action to the struts form bean. Next write code to implement the struts action. Run the application on the embedded j2ee container. That’s it. The only place where coding was needed was implementing the business logic that handles the actual user validation rule.
