Module 7 Duration
5 Days

What you will learn
JavaServer Pages(TM) (JSP(TM) page) technology and servlets are the key web-tier technologies defined in the Java(TM) Platform, Enterprise Edition (Java EE platform). The Web Component Development With Servlet and JSP(TM) Technologies, Java EE6 course provides experienced developers of Java technology applications the knowledge and skills to quickly build web applications suited to any Java EE 6 application server using JSP and servlet technologies. Students are exposed to the current methods for analyzing, designing, developing, and deploying web applications with Java technologies. Lab exercises provide students 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. This course is also an excellent method of preparing for the Oracle Certified Professional, Java Platform, Enterprise Edition 6 JavaServer Pages and Servlet Developer certification examination.
