Context description

The context element represents a web application and runs on a specific VM. Each web application is based on a web application archive (WAR) file or a directory that contains the decompressed content of the war file. By matching the longest possible prefix of the request URI with the context path of each context, Catalina selects the corresponding web application to process HTTP requests. Once selected, according to the servlet ing defined in the Web application deployment descriptor file, context selects a correct servlet to process incoming requests. Servlet mappings must be defined in/WEB-INF/Web. XML in the Web application directory hierarchy. You can nest any number of context elements in a host element. The path of each context must be unique and defined by the path attribute. In addition, you must define a context whose path length is 0. This context is called the default web application of the VM and is used to process requests that cannot match any context path. In addition to nesting the context element in the host element, you can also store them in a single file. put XML in the $ catalina_home/CONF/[enginename]/[hostname]/directory. (Note: Catalina is the alias of Tomcat)
