webcontainer removes the servlet by calling destroy()
When a request is mapped to a JSP page, the web container first checks whether the JSP page’s servlet is older than the JSP page. If the servlet is older, the web container translates the JSP page into a servlet class and compiles the class. Transalated JSP is saved as jspName_jsp.java. After the page has been translated and compiled, the JSP page’s servlet mostly follows the servlet life cycle
