Developing Java Web Applications: Hands-On
Integrating Java Servlets and JavaServer Pages
You Will Learn How To
- Build data-driven Web applications with server-side Java technologies
- Add a Web interface to your databases using Java servlets
- Generate dynamic Web pages with JavaServer pages (JSP)
- Personalise content for users with cookies and sessions using the Java Servlet API
- Integrate JSP custom tags to minimise scriptlet code
- Create Web applications using the Struts framework
Course Benefits
Java servlets and JavaServer Pages allow developers to leverage the power of the Java platform and create object-oriented, scalable, n-tier applications. In this course, you learn how to integrate key components of the Java Enterprise Edition (Java EE), including servlets and JSP technologies to create dynamic data-driven Web applications.
Who Should Attend
Those involved in developing Web applications with Java. Knowledge of Java at the level of Course 471, "Java Programming Comprehensive Introduction", plus real-world Java programming experience, are assumed. Knowledge of Web technologies and HTML is helpful.
