Tomcat 5 to run through the web browser configuration of the application is very easy to configure the server. The application known as the Tomcat Administration Web Application. However, Tomcat 5.5 after the installation of the core binary version is no longer available for Tomcat Administration Web Application. To install the latter requires a separate download and installation. Tomcat and Administration Web Application did not provide an automatic integrated installation process. This article about the installation and configuration process in detail.

The first step to confirm your Tomcat is installed in the Administration Web Application. First, determine the Tomcat Service is running. Then in a browser, type http://localhost:8080/admin, to see if the Tomcat Web Server Administration Tool page on Administration Web Application has been installed. You can save time, not a must-read below. If you see

The fourth step will be extracting download folder under \ conf \ Catalina \ localhost \ admin.xml the
admin.xml copies of documents to TomeCat installation directory \ conf \ Catalina \ localhost.'s folder. Attention must be placed on the correct path of the folder.

The fifth step, extracting download folder server \ webapps in the admin to copy the entire folder TomeCat under the installation directory server \ webapps folder.

The sixth step, with editing features, such as the notepad to open TomeCat installation directory conf \ in the tomcat-users.xml file. In </ tomcat-user> prior to the last line, add the following line
<user username="admin" password="tomcat" roles="admin, manager"/>
Attention to the username / password can be any combination you like, but the roles = "admin" can not be altered.

The seventh step, restart Tomcat Server, in the web browser, type http://localhost:8080/admin, this time to see if your Tomcat Server Web Administration Tool's login interface, you're done. If it still can not see the above page, check your browser's proxy settings to make it acceptable to localhost.
