What are Java Servlets?
Java Servlets are alternatives to CGI and NSAPI/ISAPI web server extensions
Java Servlets are compiled code, but are loaded dynamically
- .java source file gets compiled to byte code .class file
Java Servlets are the core presentation-layer technology for J2EE
- JavaServer Pages (JSP) are built on Java Servlet “plumbing”
- Velocity template engine is a Java Servlet
- XML/XSLT transformation engines are implemented as servlets
Compiled Java Servlets (.class) are fully portable across J2EE servers and servlet/JSP engines
