Servlet Configuration
Servlet configuration follows the Servlet 2.2 deployment descriptors. Servlets generally belong in the WEB-INF/classes directory of the web application. The mapping from url to servlet is controlled by servlet mapping in the application configuration. For a complete, working example, see Servlet or experiment with the Hello, World demo.
web-app
servlet | Defines a servlet alias for later mapping.
web-app/servlet
servlet-name | Alias of the servlet
servlet-class | Class of the servlet
init-param | Initializes servlet variables.
load-on-startup | If present, starts the servlet when the server starts.
run-at | If present, executes the servlet at the specified times.
web-app
### servlet
Defines a servlet alias for later mapping.
servlet-name | The servlet's name (alias)
servlet-class | The servlet's class (defaults to servlet-name)
init-param | Initialization parameters
load-on-startup | Initializes the servlet when the server starts.
run-at | Times to execute the servlet automatically
The following example defines a servlet alias 'hello'
<caucho.com> <http-server> <servlet-mapping url-pattern='/hello.html' servlet-name='hello'/> <servlet servlet-name='hello' servlet-class='test.HelloWorld'> <init-param title='Hello, World'/> </servlet> <servlet servlet-name='cron' servlet-class='test.DailyChores'> <run-at>3:00</run-at> </servlet> </http-server> </caucho.com>
web-app/servlet
### servlet-name
Alias of the servlet
### servlet-class
Class of the servlet The CLASSPATH for servlets includes the WEB-INF/classes directory and all jars in the WEB-INF/lib directory.
### init-param
Initializes servlet variables. `servlet-param` defines initial values for `getServletConfig().getInitParameter("foo")`. The full servlet 2.2 syntax is supported and allows a simple shortcut
<caucho.com> <http-server> <servlet servlet-name='test.HelloWorld'/> <init-param foo='bar'/> <init-param> <param-name>baz</param-name> <param-value>value</param-value> </init-param> </servlet> </http-server> </caucho.com>
### load-on-startup
If present, starts the servlet when the server starts.
<caucho.com> <http-server> <servlet servlet-name='test.HelloWorld'> <load-on-startup/> </servlet> </http-server> </caucho.com>
### run-at | ### Resin 1.1
If present, executes the servlet at the specified times. <run-at> lets servlet writers execute periodic tasks without worrying about creating a new Thread. The value is a list of 24-hour times when the servlet should be automatically executed. To run the servlet every 6 hours, you could use
<servlet servlet-name='test.HelloWorld'/> <run-at>0:00, 6:00, 12:00, 18:00</run-at> </servlet>
If the hour is omitted, the servlet runs every hour at the specified minute. To run the server every 15 minutes, you could use:
<servlet servlet-name='test.HelloWorld'/> <run-at>:00, :15, :30, :45</run-at> </servlet>
