The JSR 309 jar listed on JCP site is just interface. HP will have its own
implementation like Mobicents is having its own. You need to get the impl
jar file in your class-path which I guess HP will soon have as Reference
Implementation but still its not there.
What are you trying to achieve?
Have you seen Mobicents Sip Servlets integration with Mobicents Media
Server?
