JViews JSF application configuration

Required settings

The standard configuration needed by a JSF application in the web.xml of your application server is as follows.

<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>

The JViews JSF application needs two additional settings in order to execute correctly, namely:

JViews Controller Servlet

The JViews Controller Servlet is in charge of loading the various resources used by the JViews JSF application like JavaScript™ libraries, images and the like. But more importantly it provides clients with the latest state of their views capabilities as well as their dynamically generated images.

You must declare and map the JViews Controller Servlet. To do this, use the following code.

<servlet-name>Controller</servlet-name>

<servlet-class>ilog.views.faces.IlvFacesController</servlet-class>

<load-on-startup> 1 </load-on-startup>

</servlet>

<servlet-mapping>

<servlet-name>Controller</servlet-name>

<url-pattern>/_contr/*</url-pattern>

</servlet-mapping>

ilog.views.faces.CONTROLLER_PATH

This setting provides users with the flexibility of defining a custom <url-pattern> for the JViews Controller Servlet that is appropriately communicated to the JViews JSF application so that proper execution takes place.

You must set the ilog.views.faces.CONTROLLER_PATH context parameter which must match the content of the <url-pattern> of the JViews Controller Servlet without the wildcard part. For example, the following code would appear after the code for the JViews Controller Servlet.

<context-param>

<param-name>ilog.views.faces.CONTROLLER_PATH</param-name>

<param-value>/_contr</param-value>

</context-param>

Optional settings

The following optional setting is available in the JViews Framework Faces:

ilog.views.faces.CONTENT_LENGTH_ENABLED

The ilog.views.faces.CONTENT_LENGTH_ENABLED setting allows users to specify if the underlying servlet that is used to generate the client-side representation of the JViews Faces Components is interacting with the client in a buffered mode or not. More specifically, it enables the communication of the content length when the server responds to client requests. This provides more optimal interaction between the client and the server.

For more insights see javax.servlet.ServletResponse.setContentLength and related material on the Internet.

This setting is exposed through the context parameter facility and can be set as follows.

<context-param>

<param-name>ilog.views.faces.CONTENT_LENGTH_ENABLED</param-name>

<param-value>true</param-value>

</context-param>

NOTE Although optional, it is recommended to set this setting always to true.
