Cocoon and Java

[Matteo Mancini]

Hi all, I need to know something about the best way to interact with Cocoon object via java code. More exactly I need to retrieve the Session Object in order to set and get attributes.   I tried some ways I found inside cocoon user guide but I faced many problems because  Cocoon java packages have so many interfaces and classes. I tried those dealing with HttpSession, HttpServlet and CocoonServlet classes. Noone seems to work. I always catch a NullPointerException when I tried to get a reference or instantiate them. There should be somethng I miss !!!!   Can anyone suggest me how to do?     Thanks in advance   Matteo Mancini
