61. HttpClient
By: aathishankaran : 2007-02-14
Description: An HttpClient can be used to send requests and retrieve their responses. An HttpClient is created through a builder. The builder can be used to configure per-client state, like: the preferred protocol version ( HTTP/1.1 or HTTP/2 ), whether to follow redirects, a proxy, an authenticator, etc. Once built, an HttpClient is immutable, and can be used to send multiple requests
62. Packaging Servlets
By: aathishankaran : 2007-02-14
Description: In a production environment, multiple programmers may be developing servlets for the same server. So, placing all the servlets in the top-level servlet directory results in a massive hard-to-manage directory and risks name conflicts when two developers accidentally choose the same servlet name. Packages are the natural solution to this problem. Using packages results in changes in the way the servlets are created, the way that they are compiled, and the way they are invoked.
63. Servlets
By: aathishankaran : 2007-02-14
Description: Servlets are Java technology's answer to Common Gateway Interface (CGI) Programming. They are programs that run on a Web server, acting as middle Layer between a request coming from a Web browser or other HTTP client and databases or applications on the HTTP server.

65. The Advantages of JSP
By: aathishankaran : 2007-02-14
Description: JSP has a number of advantages over many of its alternatives. Here are a few of them.
66. The Advantages of Servlets Over Traditional CGI
By: aathishankaran : 2007-02-14
Description: Java servlets are more efficient, easier to use, more powerful, more portable, safer, and cheaper than traditional CGI and many alternative CGI-like technologies.
67. The Servlet Life Cycle
By: aathishankaran : 2007-02-14
Description: You might know that only a single instance of a servlet gets created, with each user request resulting in a new thread that is handed off to doGet or doPost as appropriate. I'll now be more specific about how servlets are created and destroyed, and how and when the various methods are invoked. I'll give a quick summary here, then elaborate in the following subsections.
68. Combining Scriptlets with HTML
By: aathishankaran : 2007-02-13
Description: We have already seen how to use the "out" variable to generate HTML output from within a scriptlet in previous articles. For more complicated HTML, using the out variable all the time loses some of the advantages of JSP programming. It is simpler to mix scriptlets and HTML.
69. JSP Directives
By: aathishankaran : 2007-02-13
Description: In the previous article we had explained about the java.util.Date in the examples in the previous articles. Perhaps you wondered why we don't just import java.util.*; It is possible to use "import" statements in JSPs, but the syntax is a little different from normal Java
70. Form processing in JSP
