Sip Servlet setAttribute mobicent -


i'm facing on problem set attribute of sip servlet. i'm trying send 200 ok , when receive 200 ok different source. i've thought in way:

protected void doinvite(sipservletrequest req) throws servletexception, ioexception {     //...     sipsession session = req.getsession();     sipservletresponse response = req.createresponse(200);     session.setattribute("reqresponse", response);     /... }

and so, when receive 200 ok other side:

protected void dosuccessresponse(sipservletresponse resp)     //...     throws servletexception, ioexception {     sipservletresponse response = (sipservletresponse) session.getattribute("reqresponse");             response.send();     //....     }

but when try response.send() have error:
