I am very new in Java web technologies. Previously I have worked with other languages to create web contents. My question is this book can give me some hints about what are the strengths of JSP compares with other web solutions?
One of the benefits of the Servlet/JSP technologies is scalability, especially compared to older technologies that spawned a new process for every HTTP request. A servlet instance stays in memory after the first invocation, waiting to serve other requests. Using Servlet/JSP also means you get all the benefits Java has to offer (cross-platform, extensive libraries, security, etc).
