Tomcat functions as a servlet container developed at the Apache Software Foundation. Tomcat implements the servlet and the JavaServer Pages (JSP) specifications from Sun Microsystems. That is to say, it provides an environment for Java code to run in cooperation with a web server. It also adds tools for configuration and management, but it can also be configured by editing configuration files that are normally XML-formatted. Because Tomcat includes its own HTTP server internally, it is also considered to be a standalone web server. Image File history File links Jakarta Tomcat Logo Source: http://jakarta. ...

Environment
Tomcat is a web server that supports servlets and JSPs. Tomcat comes with the Jasper compiler that compiles JSPs into servlets. The term web server can mean one of two things: A computer that is responsible for accepting HTTP requests from clients, which are known as web browsers, and serving them web pages, which are usually HTML documents. ...

The Tomcat servlet engine often appears in combination with an Apache webserver or other web servers. Tomcat can also function as an independent web server in itself. Earlier in its development, the perception existed that standalone Tomcat was only suitable for development environments and other environments with minimal requirements for speed and transaction handling. However, that perception is no longer true. Tomcat is increasingly being used as a standalone web server in high-traffic, high-availability environments. Apache HTTP Server is a free software/open source HTTP web server for Unix-like systems (BSD, Linux, and UNIX systems), Microsoft Windows, Novell Netware and other platforms. ...

Development status Members of the Apache Software Foundation and independent volunteers develop and maintain Tomcat. Users have free access to the source code and to the binary form of Tomcat under the Apache License. The initial Tomcat release appeared with versions 3.0.x. Tomcat 5.5.x, the latest production quality release as of 2005, implements the Servlet 2.4 and JSP 2.0 specifications. Versions 4.0 and later use the Catalina servlet container internally.

Directory structure The typical and default directory hierarchy of a Tomcat installation comprises the following: - bin - startup, shutdown and other scripts and executables
- common - common classes that Catalina and web applications can use
- conf - XML files and related DTDs to configure Tomcat
- logs - Catalina and application logs
- server - classes used only by Catalina
- shared - classes shared by all web applications
- webapps - directory containing the web applications
- work - temporary storage for files and directories
However, alternative configurations are possible. The documentation that ships with Tomcat contains more details.

History Tomcat started off as a servlet specification implementation by James Duncan Davidson who worked as a software architect at Sun. He later helped in making the project open source and in its donation by Sun to the Apache Software Foundation. James Duncan Davidson, born July 29th, 1970 in Lubbock Texas, raised in Oklahoma and Texas. ...

Open source refers to projects that are open to the public and which draw on other projects that are freely available to the general public. ...
Davidson had initially hoped that the project would become open-sourced, and since most open-source projects had O'Reilly books associated with them featuring an animal on the cover, he wanted to name the project after an animal. He came up with Tomcat, since he reasoned the animal represented something that could take care of and fend for itself. His wish to see an animal cover eventually came true, when O'Reilly published their Tomcat book with a tomcat on the cover. OReilly Media (formerly OReilly & Associates) is an American media company established by Tim OReilly that publishes books and web sites and produces conferences on computer technology topics. ...
Tomcat has several meanings, including: A male cat. ...
