JSF Pertanyaan dan Jawaban Wawancara

Question: How do I configure the configuration file?

Answer: The configuration file used is our old web.xml, if we use some IDE it will be pretty simple to generate but the contents will be something like below:


<?xml version="e;1.0"e; encoding="e;UTF-8"e;?>
<web-app version="e;2.4"e; xmlns="e;http://java.sun.com/xml/ns/j2ee"e;
xmlns:xsi="e;http://www.w3.org/2001/XMLSchema-instance"e;
xsi:schemaLocation="e;http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"e;>
<context-param>
<param-name>com.sun.faces.verifyObjects</param-name>
<param-value>false</param-value>
</context-param>


<context-param>
<param-name>com.sun.faces.validateXml</param-name>
<param-value>true</param-value>
</context-param>


<context-param>
<param-name>javax.faces.STATE_SAVING_METHOD</param-name>
<param-value>client</param-value>
</context-param>


<servlet>
<servlet-name>Faces Servlet</servlet-name>
<servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>


<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>/faces/*</url-pattern>
</servlet-mapping>


<session-config>
<session-timeout>
30
</session-timeout>
</session-config>


<welcome-file-list>
<welcome-file>
index.jsp
</welcome-file>
</welcome-file-list>
</web-app>

The unique thing about this file is ?servlet mapping?. JSF pages are processed by a servlet known to be part of JSF implementation code. In the example above, it has extension of .faces. It would be wrong to point your browser to http://localhost:8080/MyJSF/login.jsp, but it has to be http://localhost:8080/MyJSF/login.faces. If you want that your pages to be with .jsf, it can be done with small modification :-),

<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>*.jsf</url-pattern>
