[Java lista] glassfish stateful webservice

[Balázs Hollósi]

sziasztok

gondoltam kiprobalom a stateful webservice tamogatasat a
glassfish-nek, viszont egy kis problemam akadt.

alap cikk: https://jax-ws.dev.java.net/nonav/2.1/docs/statefulWebservice.html

Viszont a session kiszolgalas mar elszall nullpointerrel. (es ha jol
latom, ez az egesz com.sun.xml.ws.developer package csak gf2 alatt van
meg, gf3 nem tamogatja?)

Talaltam egy bejegyzest, ami kisertetiesen ua, de a workaround nalam
nem segitett.
https://wsit.dev.java.net/issues/show_bug.cgi?id=309

szinte minden ua, mint a peldaban. probalta mar valaki ezt a vonalat?
vagy van valami 3rdparty megoldas ra?

koszi,
