JavaServer Pages™ (JSP™) technology and servlets are the key web-tier technologies defined in the Java™ Platform, Enterprise Edition (Java EE platform). In this course, experienced developers of Java technology applications will gain the knowledge and skills to quickly build web applications suited to any Java EE 6 application server using JSP and servlet technologies. You will be exposed to the current methods for analyzing, designing, developing, and deploying web applications with Java technologies. Lab exercises provide you with experience in constructing and deploying the small-to-medium scale web applications found in intranet and low-volume commercial sites. The course features the Java EE 6 technology and uses the Java EE 6 SDK and the Glassfish Application Server. You will perform the lab exercises using the NetBeans™ Integrated Development Environment (IDE). This course is excellent preparation for the Sun Certified Servlet and JSP Developer certification exam.
