**************************Java Servlettutorial*******************

Servlets are most often used to process or store a Java class inJava EE that conforms to the Java Servlet API,[2] a standard forimplementing Java classes that respond to requests. Servlets couldin principle communicate over any client–server protocol, but theyare most often used with the HTTP protocol. Thus "servlet" is oftenused as shorthand for "HTTP servlet".[3] Thus, a software developermay use a servlet to add dynamic content to a web server using theJava platform. The generated content is commonly HTML, but may beother data such as XML. Servlets can maintain state in sessionvariables across many server transactions by using HTTP cookies, orrewriting URLs.

To deploy and run a servlet, a web container must be used. A webcontainer (also known as a servlet container) is essentially thecomponent of a web server that interacts with the servlets. The webcontainer is responsible for managing the lifecycle of servlets,mapping a URL to a particular servlet and ensuring that the URLrequester has the correct access rights.

The Servlet API, contained in the Java package hierarchyjavax.servlet, defines the expected interactions of the webcontainer and a servlet.[3]

A Servlet is an object that receives a request and generates aresponse based on that request. The basic Servlet package definesJava objects to represent servlet requests and responses, as wellas objects to reflect the servlet's configuration parameters andexecution environment. The package javax.servlet.http definesHTTP-specific subclasses of the generic servlet elements, includingsession management objects that track multiple requests andresponses between the web server and a client. Servlets may bepackaged in a WAR file as a web application.

Servlets can be generated automatically from Java Server Pages(JSP) by the JavaServer Pages compiler. The difference betweenservlets and JSP is that servlets typically embed HTML inside Javacode, while JSPs embed Java code in HTML. While the direct usage ofservlets to generate HTML (as shown in the example below) hasbecome rare, the higher level MVC web framework in Java EE (JSF)still explicitly uses the servlet technology for the low levelrequest/response handling via the FacesServlet. A somewhat olderusage is to use servlets in conjunction with JSPs in a patterncalled "Model 2", which is a flavor of themodel–view–controller.

After learn this app Java Servlet tutorial will be help you knowservlet and implement a servlet with java.

C++ tutorial 1.1 APK
SAM STORE
C++, pronounced "C plus plus," is aprogramming language that was built off the C language. The syntaxof C++ is nearly identical to C, but it has object-orientedfeatures, which allow the programmer to create objects within thecode. This makes programming easier, more efficient, and some wouldeven say, more fun. Because of the power and flexibility of thelanguage, most software programs today are written in C++.With This app you will get C plus from basic to Advantages.Thank everyone for support SAM STORE
JSP tutorial 1.1 APK
SAM STORE
JavaServer Pages (JSP) is a technology thathelps software developers create dynamically generated web pagesbased on HTML, XML, or other document types. Released in 1999 bySun Microsystems,[1] JSP is similar to PHP and ASP, but it uses theJava programming language.To deploy and run JavaServer Pages, a compatible web server with aservlet container, such as Apache Tomcat or Jetty, isrequired.With this app you can begin very easy with JSP.
Selenium tutorial 1.3 APK
SAM STORE
Selenium is a portable software testingframework for web applications. Selenium provides a record/playbacktool for authoring tests without learning a test scripting language(Selenium IDE). It also provides a test domain-specific language(Selenese) to write tests in a number of popular programminglanguages, including C#, Groovy, Java, Perl, PHP, Python, Ruby andScala. The tests can then be run against most modern web browsers.Selenium deploys on Windows, Linux, and OS X platforms. It isopen-source software, released under the Apache 2.0 license, andcan be downloaded and used without charge.With this app you will easy to learn Selenium offline.
