What Is Pre Initialization Of A Servlet? |
|
Answer» A container doesn't initialize the servlets when it starts up. It initializes a servlet when it receives a REQUEST for that servlet first time. This is called lazy loading. The servlet specification DEFINES the <LOAD-on-startup> ELEMENT, which can be specified in the deployment descriptor to make the servlet container load and initialize the servlet as soon as it starts up. The process of loading a servlet before any request comes in is called PRELOADING or pre initializing a servlet. A container doesn't initialize the servlets when it starts up.
