A.1 Overview of Servlets and 

JavaServer Pages

Advantages of Servlets

  Efficient: threads instead of OS processes, one servlet copy, 

persistence

  Convenient: lots of high level utilities

  Powerful: talking to server, sharing data, pooling, persistence

  Portable: run on virtually all operating systems and servers

  Secure: no shell escapes, no buffer overflows

  Inexpensive: inexpensive plug ins if servlet support not bundled

Advantages of JSP

  Versus ASP: better language for dynamic part, portable

  Versus PHP: better language for dynamic part

  Versus pure servlets: more convenient to create HTML

  Versus SSI: much more flexible and powerful

  Versus JavaScript: server side, richer language

  Versus static HTML: dynamic features
