Course Description:

This course covers all the skills necessary for effective Java web application development. It emphasizes portable code practices following J2EE standards, which will function correctly on any standards-compliant Java web application server. Participants will develop a complete web application, including client-side form validation with JavaScript, form processing with servlets and JSP and database integration with JDBC. This course is an accelerated combination of Servlet, JSP and JDBC courses.

You can learn to …

·       Perform HTML form processing with Java servlets

·       Create dynamic page content with Java Server Pages

·       Define custom JSP tags for rapid web development

·       Create and integrate JDBC-enabled business objects

·       Perform client-side form validation with JavaScript (extended-day version)
