Perte de session en publiant et NotSerializableException sur org.apache.tomcat.dbcp.dbcp.BasicDataSource

[Roger_Rabbit]

Bonjour,

je travaille sur un projet JSF déjà bien avancé, développé avec Eclipse 3.6.
Nous avons plusieurs webapps tournant sur tomcat (6.0) (avec une couche hibernate et une base MySql tout en dessous).
Nos configs sont plutôt bien rodées... et nous ne rencontrons guère de problèmes les concernant.

Mais récemment, lors de l'installation d'un environnement de dev pour un nouveau développeur, nous avons rencontré un os :
lorsqu'il modifie ses pages xhtmls, et les sauve, Eclipse se charge naturellement de les publier sur le serveur tomcat. Mais là où celà coûte uniquement un rafraichissement (cache inclus) du navigateur chez nous (ctrl+F5), celà provoque une perte de session systématique chez lui.
Cette perte de session s'accompagne d'une exception (celle que j'ai citée en titre : le contenu de l'exception est plus bas).

C'est très handicapant pour le développement car celà signifie qu'il doit systématiquement se reloguer lorsqu'il travaille dans la partie connectée du site..

J'ai donc essayé en vain de trouver la source de ce problème, mais ai fait choux blanc jusque là. C'est donc en espérant que l'un(e) d'entre vous aura une idée à ce sujet que je vous conte mes malheurs ici!

Merci déjà de m'avoir lu jusque là, et -j'espère- d'avance de vos remarques et/ou suggestions!

[lunatix]

il semblerait que la connexion a la base de données soit placée dans la session utilisateur (ce qui est en général plutot une erreur). et du coup : tomcat ne peut pas serialiser et ecrire cette session : d'ou la perte

si ca n'arrive pas sur les autres postes : c'est probablement du a une modification du projet en local. (ou que les autres postes ne sont pas encore a jour)

Bonjour, et merci de ta réponse.

Je vais par contre certainement poser une question bête : où dois-je chercher l'information / le bon paramètre? (je n'ai pas réussi à trouver l'info sur le web ; je manque probablement des bons mots clef!)
Il me semble qu'il me faudrait chercher du côté du context.xml du serveur, ou éventuellement du server.xml.

Au cas où je ne me tromperais pas, je copie ici le contenu de ces deux fichiers (avec un peu de nettoyage dans les commentaires pour que ce soit plus lisible!):
Context.xml
