Tomcat

Tomcat is the Apache Software Foundation ( Apache Software Foundation ) Jakarta project in a core project, by Apache, Sun and some other companies and individuals to develop and become. Because of the Sun participation and support, the new Servlet and JSP code can always be reflected in Tomcat Tomcat 5, support for the latest Servlet 2.4 and JSP 2 specification. Because Tomcat advanced technology, stable performance, and free, and thus by Java fans and got some software developers approbate, become current popular Web application server. The latest version is 7.
Tomcat is very popular with programmers love, because it runs system resource occupied by small, good scalability, load balancing and mail service support system development and application of commonly used functions; and it continues to improve and perfect, any one interested programmers can change it or in which add new function. Tomcat is a lightweight application server, in the small and medium systems and concurrent access to the user not many occasions to be widely used, is to develop and debug JSP program of choice. For a beginner, can think so, as in a machine to configure Apache server, we can use it to respond to a HTML page access request. In fact Tomcat part of Apache server extensions, but it is run independently, so when you run tomcat, it actually acts as a Apache independent processes separately run. The trick here is that, when properly configured, Apache HTML page service, but Tomcat actually running the JSP page and Servlet. In addition, Tomcat and IIS, Apache, Web server, HTML page with processing function, and it is a Servlet and JSP container, independent of the Servlet container Tomcat is the default mode. However, Tomcat static HTML as the Apache server. At present the latest version of Tomcat 7.0.22 Released.
Tomcat was originally developed by Sun software architect James Duncan Davidson development. He later helped to turn it into an open source project, and by the Sun contribution to the Apache software foundation. Since most open-source projects O 'Reilly are out of a book, and the cover is designed into an animal of the sketch, so he hopes will this project is named after an animal. Because he hoped that this animal can take care of themselves, ultimately, he will be named Tomcat ( English cat or other male cats ). But O Reilly published Tomcat introduce books cover was designed as a male image. While the Tomcat Logo and the mascot is also designed as a male cat.
Apache Tomcat 7.x is currently the development focus. It took Tomcat 6.0.x on the basis of merit, the Servlet 3, JSP 2.2 and EL 2.2 features such as support. In addition to this list is as follows: improvement of Web application memory leak detection and prevention enhanced management program and server management procedures for the safety protection of the general CSRF.
Apache Tomcat ( 18 ) to support web applications, external content in direct reference reconstruction ( connectors, lifecycle ) and many core code of the Apache Tomcat 6.x drawing on a comprehensive review of Tomcat 5.5.x on the basis of merit, implementation of the Servlet 2.5 and JSP 2.1 features such as support. In addition to improving list is as follows: memory usage optimization, greater capacity of IO, Apache Tomcat 5.x Apache Tomcat reconstruction of cluster 5.5.x and Apache Tomcat 5.0.x for Servlet and JSP support is the same. Large amounts of the underlying code in significant modifications, brings the performance, stability and the upgrading of the overall cost. Please refer to Apache Tomcat 5.5 update log. Apache Tomcat 5.0.x in Apache Tomcat 4.1 based on doing a lot of changes, including: performance optimization and to reduce the waste recovery action reconstruction program deploy, optionally via a separate deployment procedures, allowing the application of a web into the product verification and compilation of it based on the JMX server monitor and management of the web program to improve Taglibs supporting capacity, including improved data pool and tag plug-in improved platform integration, including Windows and Unix based on JMX embedded enhanced security management support integrated session cluster file extension.
Most commercial JavaEE server provides a powerful management interface, and mostly with easy to understand Web application interface. Tomcat according to his own way, also provides a sophisticated management tools, and in no way comparable to those of commercial competition. Tomcat Admin Web Application initially in the 4.1 version, the function includes the management of context, data source, user and group etc.. Of course, can also be managed like initialization parameters, user, group, role a variety of database management. In the subsequent versions of these functions will be, to a great expansion, but the existing function has a very practical. Admin Web Application is defined in the automatic deployment files: CATALINA_BASE / webapps / admin.xml. To edit this file, to determine the Context docBase parameter is the absolute path. That is to say, CATALINA_BASE / webapps / admin.xml path is the absolute path. As another option, can also remove the automatic deployment files, in an server.xml file to create a Admin Web Application context, the effect is the same as. Admin Web Application cannot manage this application, in other words, in addition to delete the CATALINA_BASE / webapps / admin.xml, could do nothing. If you use the UserDatabaseRealm ( default ), will need to add an user and a role to CATALINA_BASE / conf / tomcat-users.xml file. You edit this file, add a named" admin" role into the file, as follows: < role name =" admin" / > as the need for a user, and the user 's role is to " admin". As the user of the existence of such, add a user ( change the code to make it more safe ): < user name =" admin" password =" deep_dark_secret" roles =" admin" / > when completed these steps, please restart Tomcat, visit http: / / localhost: 8080 / Admin, will see a login interface. Admin Web Application based on the container management security mechanism, and using the Jakarta Struts framework. As soon as the" admin" role of the user to log in to the admin interface, will be able to use this configuration management interface Tomcat.
Manager Web Application let you through a than Admin Web Application more simple user interface, to perform some simple Web application tasks. Manager Web Application is defined in an automatic deployment file: CATALINA_BASE / webapps / manager.xml. To edit this file, to ensure that the context docBase parameter is the absolute path, that is to say the CATALINA_HOME / server / webapps / Manager absolute path. If you are using UserDatabaseRealm, you need to add a role and a subscriber to the CATALINA_BASE / conf / tomcat-users.xml file. Next, edit this file, add a "manager" role to the file: < role name =" manager" > also need to have a role as " manager" user. Like the existing users, add a new user ( change the code to make it more safe ): < user name =" manager" password =" deep_dark_secret" roles =" manager" / > and then restart Tomcat, visit http: / / localhost / Manager / list, will see a very simple text management interface, or visit http: / / localhost / Manager / HTML / list, will see a HMTL management interface. Either way it means you Manager Web Application has now started. Manager application may not have administrative privileges on the basis of system, the installation of a new Web application, for testing. If we have a new web application in the / home / user / hello in, and want to install it into / Hello, in order to test the application, can do so, the first file box" / Hello" ( as when accessing the path ), in the second text box input" file: / home / user / Hello" ( as Config URL ). Manager application also allows the stop, restart, removal and to deploy a web application. To stop an application so that it can not be accessed, when users try to access this is stopped when applied, will see a 503 error --" 503 - This application is not currently available". Removes a web application from Tomcat, refers only to run copy deleted this application, if the restart Tomcat, deleted applications will appear again ( i.e., removed and is not removed from the hard disk ).
There are two ways to deploy web services in the system. 1 > copy the WAR file or web application folder ( including the all the content of the web ) to $CATALINA_BASE / webapps directory. 2 > Web service establish a includes only the context content XML clip file, and the file in the $CATALINA_BASE / webapps directory. The application of web itself can be stored on the hard drive of any place. If there is a WAR file, want to deploy it, only need to put the file simply copy to CATALINA_BASE / webapps directory can be, the document must be" . War" as the extension. Once the Tomcat listening to this file, it will ( default) to the package as a subdirectory, and the WAR file file name as a subdirectory names. Next, Tomcat will be built in the memory of a context, as in server.xml document set. Of course, other essential content, from the server.xml DefaultContext access. Deploying a web application is another way to write a Context fragment of XML file, and then the files are copied to the CATALINA_BASE / webapps directory. A Context segment is not a full XML file, but a context element, as well as the application of the corresponding description. This clip file is cut out from the server.xml context element, so this episode was named" context fragments".
Once you have set the realm and validation of the method, needs to carry on the actual user login process. Generally speaking, the user login system is a very troublesome thing, must try to reduce the number of user login validation. As a default, when a user first requests a protected resource, every web application would require the user to login. If running a number of web application, and every application need for a separate user authentication, it looks a bit like the user. Users don't know how to get a plurality of separate applications are integrated into a single system, all users will not know they need access to many a same application, is very confused, why always keep log. Tomcat 4" single sign-on" feature allows users to access the same host all web applications, only need to log in once. In order to use this function, only need to add a SingleSignOn Valve Host elements can be, as follows: < Valve className =" org.apache.catalina.authenticator.SingleSignOn" debug =" 0" / > in Tomcat after initial setup, server.xml notes which include the SingleSignOn Valve configuration example, only need to take notes, can be used. Then, any user log on to an application, for the same hosting all applied equally effective. Use the single sign-on valve has some important limitations: 1 > value must be configured and nesting in the same.
The Tomcat server is a free open source Web application server, the latest version is 6.0.20( stop to 2009-03-20). Tomcat is the Apache Software Foundation ( Apache Software Foundation ) Jakarta project in a core project, by Apache, Sun and other companies and individuals to develop and become. Because of the Sun 's participation and support, the new Servlet code and JSP code can always be reflected in Tomcat Tomcat5, support for the latest Servlet 2.4and JSP 2norm . Because Tomcat technology advanced, stable performance, and free, so by the Java enthusiasts and has been the favorite part of software developers approbate, become the popular Web application server.

In fact part Tomcat is the Apache server extensions, but it is independent operation, so when you run tomcat, it actually as a Apache independent processes run separately. The trick is, when properly configured, Apache HTML page service, Tomcat actually run JSP pages and Servlet. surface and in addition, Tomcat and IIS, Apache and Web server. With HTML page, processing power, and it is a Servlet and JSP contai
