Question

Need to add a Java class (named HistoryBean in my project) to the ServletContext. I do not want to create new instance of the HistoryBean class in the different Servlets that I have inside my project. I want to get it from the ServletContext. Please help me with suggestions.

Answer 1

You can do that in a ServletContextListener:

public void contextInitialized(ServletContextEvent e) {
     e.getServletContext().setAttribute("historyBean", new HistoryBean());
}

Register your listener with @WebListener or with <listener>..</listener> in web.xml.
