Tomcat 6 session persistante

Tomcat 6 session persistante - Exception

J'ai des exceptions qui apparaissent au demarrage et au rechargement du contexte. Tomcat 6 essaye de recharger la session ou bien de la sauvergarder.
Peux ton descaviter la serialisation de la session?
Au demarrage:

Code:

1
2
3
4
5
6
 
org.apache.catalina.session.StandardManager doLoad
GRAVE: "IOException" lors du chargement des sessions persistantes: java.io.WriteAbortedException: writing aborted; java.io.NotSerializableException:
....
org.apache.catalina.session.StandardManager start
GRAVE: Exception au chargement des sessions depuis le stockage persistant (persistent storage)

Au rechargement:

Code:

1
2
3
4
5
6
 
INFO: Le rechargement de ce contexte a démarré
org.apache.catalina.session.StandardSession writeObject
ATTENTION: Impossible de sérialiser l'attribut de session xxx pour la session 5D196C7FCE39A3460EECA8F0BFFB06AF
java.io.NotSerializableException: xxxx
...

Peux-tu nous donner un peu plus d'info STP pour les messages d'erreurs.
Quel JDK utilises-tu ? (java.io.IOException implémente l'interface Serializable depuis 1.4.2 au moins)

PPDL.

J'utilise la jvm Java HotSpot(TM) Client VM (build 1.6.0-b105, mixed mode, sharing).

Cela n'est pas du a ma migration, C simplement que l'on mettez rien auparavant dans la session...

C'est peut etre la solution j'essairai plus tard:
