You deploy a SIP module as described in Tools for Deployment. A SIP module that includes web module features is converged and can be assembled in either a WAR or SAR file. For a converged web/SIP module, you can use all the features described in Deploying a WAR Module except session persistence. To deploy a SIP module in an application (EAR file), assemble it as a converged web/SIP module in a WAR file.
You can optionally use a sun-sip.xml file, or both a sun-web.xml and a sun-sip.xml file for a converged application, to specify extra deployment settings. If you use both, the sun-web.xml file configures the web container and the sun-sip.xml file configures the SIP container.
If a SIP module accesses a DataSource that is not specified in a resource-ref in sun-sip.xml, or there is no sun-sip.xml file, the resource-ref-name defined in sip.xml is used. A warning message is logged recording the JNDI name used to look up the resource.
