What Is...every file format in the world - A through E. Keyboard shortcuts. This article lists keyboard shortcuts in Mozilla Firefox. The shortcuts only work if they are not used by the desktop environment or window manager. If you have enabled Emacs-style text editing shortcuts in GNOME, they will also work in Firefox. When an Emacs text editing shortcut conflicts with the default shortcuts (as occurs with Ctrl+K), the Emacs shortcut will take precedence if focus is inside a text box (which would include the address bar and search bar). In such cases you should use the alternate keyboard shortcut if one is listed below. These shortcuts require the tab bar to be “in focus”. Currently, the only way to do this is to focus an adjacent object and “tab into” the tab bar, for instance, by hitting Ctrl + Lcommand + L to focus the address bar, and then Shift + Tab repeatedly until the current tab gets a colored border.

You can also use keyboard shortcuts with developer tools in Firefox. Servlet and JSP development with Eclipse WTP. Apache Tomcat. Apache Tomcat includes tools for configuration and management, but can also be configured by editing XML configuration files. Components[edit] Tomcat 4.x was released with Catalina (servlet container), Coyote (a HTTP connector) and Jasper (a JSP engine). Catalina[edit] Catalina is Tomcat's servlet container.

Catalina implements Sun Microsystems' specifications for servlet and JavaServer Pages (JSP). In Tomcat, a Realm element represents a "database" of usernames, passwords, and roles (similar to Unix groups) assigned to those users. Different implementations of Realm allow Catalina to be integrated into environments where such authentication information is already being created and maintained, and then use that information to implement Container Managed Security as described in the Servlet Specification.[1] Coyote[edit] Coyote is Tomcat's HTTP Connector component that supports the HTTP 1.1 protocol for the web server or application container. Jasper[edit] Jasper is Tomcat's JSP Engine. Improve Your Google Search Skills [Infographic]
