[SIPForum-discussion] Creation of INVITE in Sailfin throws an Exception

[Hemant Kumar]

Hi All,

I am facing a weired issue with sailfin while creating a new INVITE message
from a SIP Servlet listener's *servletInitialized* method using below API -

*createRequest(appSession, "INVITE", fromAddress, toAddress)*

My expectation is - the INVITE should be created once the deployment of
application hosting the servlet is complete (the servlet is defined as
load-on-startup).

This works as expected when I just deploy the application without
restarting the sailfin. But on restart of sailfin when my application tries
to create the INVITE it fails with following exception -

*Error starting web context
StandardEngine[com.sun.appserv].StandardHost[server].StandardContext[/presence]
on virtual server server** *

**
* *

*java.lang.NullPointerException*
* *
