Pourquoi les getters ne renverraient pas une collection vide ?
by Brendan Le Ny 24 Nov '14

24 Nov '14

Actuellement, une propriété avec une multiplicité renvoie une collection null si on appelle le getter, pourquoi ne pas initialiser cette collection en lazy (on le fait bien dans le add) ? Voire même, pourquoi pas interdire d'appeler le setter avec null (sauf si Hibernate l'impose) ? Il me semblait y avoir une raison mais elle ne me revient plus. -- Brendan Le Ny, Code Lutin bleny(a)codelutin.com (+33) 02 40 50 29 28

Pool C3p0 non fermé

Bonjoir, Actuellement, lors d'un hot redeploy dans tomcat, le pool c3p0 semble garder les connexions ouvertes. Voici les traces au redémarrage: rave: The web application [/xxx] appears to have started a thread named [C3P0PooledConnectionPoolManager[identityToken->z8kflt90l3muy4yyzl36|6c187ab5]-AdminTaskTimer] but has failed to stop it.

This probably means that an application using c3p0 was undeployed, but not all PooledDataSources were closed prior to undeployment. This may lead to resource leaks over time. Please take care to close all PooledDataSources. J'ai trouvé un gros gros hack qui fonctionne: http://stackoverflow.com/a/7472386 ce qui semble bien démontrer qu'il y a un problème quelque part avec Topia/Hibernate (c3p0?).

Composition et cascade
by Eric Chatellier 20 May '14

20 May '14

Bonjour, Dans la PJ, les relations utilisent des compositions, mais les cascades générées sont: cascade="delete" C'est typiquement le boulot d'hibernate de sauvegarder ces instances, et je ne devrais pas à avoir à forcer la sauvegarde manuellement. Mais est-ce généralisable à toutes les compositions ? Cordialement, Eric Chatellier -- Éric Chatellier - www.codelutin.com - 02.40.50.29.28
