Servlets Certification
About Servlets
Servlets are Java classes that are used to extend the capabilities of servers that host applications accessed by means of a request-response programming model. They provide a way for developers to write Java code that runs on the server side and can handle HTTP requests and generate dynamic content for web applications.
A servlet receives an HTTP request, performs some processing, and generates an HTTP response. The processing can include interacting with a database, performing calculations, or calling other web services. The response can include HTML, XML, JSON, or other data formats.
Servlets are typically used in conjunction with a web server, such as Apache Tomcat or Jetty, which provides a runtime environment for servlets to execute and handle incoming requests. They can be invoked by a web browser or other HTTP client, and are often used to handle requests that are generated by web forms or other user interactions.
Servlets have been around since the late 90s and were the first standard for developing Java-based dynamic web content. Nowadays, JavaServer Faces (JSF), Spring MVC and other Java frameworks are more commonly used, but servlets are still widely used in many web applications.
Who should take the Servlets Certification exam?
A Servlets course would be beneficial for Java developers and web developers who want to create dynamic, interactive web applications. Servlets are Java classes that run on the server side of a web application and handle the request and response processing. The course would cover topics such as servlet lifecycle, request and response handling, and session management. It would also provide hands-on experience with developing and deploying servlets using popular Java web frameworks such as JavaServer Faces (JSF) and Spring MVC.
Servlets Certification Course Outline
A servlet is a Java programming language class that is used to extend the capabilities of servers that host applications accessed by means of a request-response programming model. Some common topics that might be covered in a course on servlets include:
The basics of the Java Servlet API and the Servlet interface
The structure of a servlet, including the init(), service(), and destroy() methods
The ServletRequest and ServletResponse classes, and how they are used to handle client requests and server responses
The HttpServlet class and how it extends the functionality of the basic Servlet class to handle HTTP requests
The ServletConfig and ServletContext classes, and how they are used to configure and manage servlets
Session management, including the HttpSession interface and cookies
Request forwarding and redirection
Servlet filters, including how to create, configure, and use filters to manipulate requests and responses
Servlet listeners, including how to create, configure, and use listeners to handle servlet-related events
Integrating servlets with other Java technologies, such as JavaServer Pages (JSP) and JavaBeans
Servlet best practices and performance optimization
Servlet security and how to protect against common attacks
