Dobry den,
mam stranku news.yhtml, ktera zobrazuje data, ktera se dotahuji pres
hibernate pomoci OpenSessionInView filteru. Pokud si necham zobrazit
primo stranku "/new.yhtml" probehne vsechno v poradku. Pokud se ale na
tuto stranku necham presmerovat z index.jsp pomoci <jsp:forward
page="/news.yhtml" /> dostanu org.hibernate.LazyInitializationException
(pri <c:redirect url="news.yhtml"/> je opet vse v poradku). Tzn, ze
OpenSessionInView se pri jsp:forward neprovede. V mapovani filteru
pritom FORWARD uveden mam.
ve stacktrace zminka o tom, ze by kod presel pres OpenSessionInView take
neni, takze myslim, ze to bude problem v mapovani filteru, ale i kdyz
pridam dalsi filter-maping s <url-pattern>/</url-pattern> tak problem
zustava.
Poradi mi nekdo?
Diky
Petr
