Configuring SIP Applications in sip.xml

2-14 Oracle Communication and Mobility Server Developer’s Guide

Defining a Servlet

The <servlet> element defines the SIP container’s servlets. A servlet requires a

servlet name <servlet-name>, and a servlet class, <servlet-class>. The name

must be unique within the application and the class must be the fully qualified name

of the servlet class, as illustrated in

Example 2–7.

Example 2–7 Servlet Name and Servlet Class

<servlet-name>MyServlet</servlet-name>

<servlet-class>com.company.example.MyServlet</servlet-class>

</servlet>

A servlet can also have its own init parameters, <init-param> and a description

<description>. When the container starts, it only instantiates and calls the init()

method for the servlets which have set the <load-on-startup> element, as shown

Example 2–8.

Example 2–8 Defining a Servlet

<servlet-name>MyServlet</servlet-name>

<servlet-class>com.mydomain.test.MySipServlet</servlet-class>

<init-param>

<param-name>logging</param-name>

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

Set if logging should be switched on (true) or not (false).

</description>

</init-param>

<init-param>

<param-name>infotainment</param-name>

<param-value>http://www.infotainmentsite.com</param-value>

The site to use as the infotainment content provider.

</description>

</init-param>

<load-on-startup/>

</servlet>

Defining the Servlet Mapping

The <servletmapping> element of the SIP servlet application deployment

descriptor defines the conditions for invoking a servlet.

Example 2–9 illustrates how a

servlet named MySipServlet can only be invoked for incoming MESSAGE requests. For

more information, see

"Servlet Mapping".

Example 2–9 Servlet Mapping

<servlet-mapping>

<servlet-name>My Sip Servlet</servlet-name>

<equal>

<var>request.method</var>

<value>MESSAGE</value>

</equal>

</pattern>

</servlet-mapping>
