JAVA WEB DEVELOPMENT USING JDeveloper

Duration: 5 days  (includes lecture and labs)

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)

Who Should to Attend:

This course is designed for programmers who want to develop web applications with servlets, JSP, JavaScript and JDBC. Prior experience with the core features of the Java language is required. We recommend that all attendees be fluent in HTML and have a prior knowledge of object-oriented or object-based programming, as well as some knowledge of SQL and relational databases.
