Configuring Struts

Struts framework use two related type of configuration file, which nust be configured properly before and application will work correctly. Both configration files are XML based. The first one is the web application deployment descriptor web.xml and the second one the Struts configuration file, it is comonly named struts-config.xml.

Configuring web.xml

There are few Struts-specific configuration options that you must configure within this file when using the struts framework.
Modify the web.xml file in /WEB-INF directory by adding the .tld file you want to use like if you are using struts-html.tld then

<taglib>
	<taglib-uri>/WEB-INF/struts-html.tld</taglib-uri> <taglib-location>/WEB-INF/struts-html.tld</taglib-location>
</taglib>

Configure the ActionServlet that will receive all the incoming request for the appliation. The two steps involved in configuring the Struts controller servlet in the web.xml are, first to use the servlet element to configure the servlet instance that can be latter mapped in the servlet mapping element. Using servlet element to configure the servlet class in web.xml

<web-app>
	<sertvlet>
		<servlet-name>some name</servlet-name>
		<servlet-class>the class name</servlet-class>
	</sertvlet>
</web-app>

Configure Servlet mapping

<web-app>
	<sertvlet>
		<servlet-name>some name</servlet-name>
		<servlet-class>the class name</servlet-class>
	</sertvlet>
	<sertvlet-mapping>
		<servlet-name>some name</servlet-name>
		<url-pattern>*.do </url-pattern>
	</sertvlet-mapping>
</web-app>
