5. What Exactly is Java? Java is 3 sets of specifications Language Spec Binary Format (VM Spec) Platform/API Specs J2SE J2EE Other Sun APIs

6. The Language Statically Typed and Dynamic Object-Oriented from the Start General Purpose You can write servlets with Java You can write a word processor with Java Multi-Threaded

7. Implementation Versus Specification Javas Web Stack Servlet JSP (Java Server Pages) JSTL (JSP Standard Tag Lib) JSF (Java Server Pages) Code and Knowledge are Portable

8. Implementations Open Source Apache Jakarta Tomcat (Servlet/JSP) Jetty Enhydra Commercial IBM Web Sphere BEA Web Logic Oracle 9iAS Caucho Resin Orion

9. J2EE Stack Java/J2SE J2EE Other Sun APIs 3 rd Party and OSS

10. Tomcat Implements Servlet Spec/JSP Spec Stable and Fast Enough Great Support HTTP Server Relationship to Apache Classic

11. Beyond Javas Web Stack From Servlet Only To JSP Only To Servlet -> JSP To Servlet -> Action -> JSP (MVC) Web Frameworks and Struts
