Pessoal, estou usando o vraptor com mysql e hibernate e quando coloco em um servidor(container é o tomcat) que temos para homologar na empresa onde trabalho, após algum tempo sem usar à aplicação acontece o seguinte erro.

com.mysql.jdbc.exceptions.jdbc4.MySqlNonTransientConnectionException. No operations allowed after connection closed. Connection was implicity closed by the driver

Alguém já teve este problema?

em produção é necessário configurar um connection pool no hibernate, pra gerenciar as conexões corretamente…

adicione o jar c3p0 no classpath, e coloque isso no seu hibernate.cfg.xml:

<property name="hibernate.connection.provider_class"
				value="org.hibernate.connection.C3P0ConnectionProvider" />
<property name="hibernate.c3p0.max_size" value="30" />
<property name="hibernate.c3p0.min_size" value="5" />
<property name="hibernate.c3p0.timeout" value="100" />

mude esses valores pro que fizer mais sentido na sua aplicação…
existem mais configurações possíveis, dá uma pesquisada

Olá!

Eu estou com o mesmo problema e tentei fazer oq vc disse, mas sem sucesso.

Baixei o c3po em http://sourceforge.net/projects/c3p0/, copiei os três jars pro web-inf/lib do meu projeto e ao iniciar o tomcat obtive o seguinte erro:

SEVERE: WSSERVLET11: failed to parse runtime descriptor: org.hibernate.HibernateException: Could not instantiate connection provider: org.hibernate.connection.C3P0ConnectionProvider"

Que classe é essa org.hibernate.connection.C3P0ConnectionProvider? onde deveria se encontrar? no hibernate?

Estou usando VRaptor3…

Lucas_Cavalcanti
Lucas_Cavalcanti

sim, é do hibernate…

o erro foi só esse? o que tem mais pra baixo no erro?

Olha, de fato… agora achei esta classe num Jar do Hibernate no meu WEB-INF/lib… mas não entendi pq o tomcat não tá achando

note The full stack trace of the root cause is available in the Apache Tomcat/6.0.28 logs.

Olhando melhor o stack trace reparei no seguinte agora:

Será q se eu colocar no hibernate.cg.xml o seguinte:

&lt;property name="hibernate.connection.autoReconnect"&gt;true&lt;/property&gt;

já resolve?
Ou tenho q fazer isso com o c3po…?

Ah, esqueci de falar… estou usando o MySQL

Opa, desculpa!

O stack trace anexo é do meu erro em deploy, sem tentar usar o c3po…

tentando usar o c3po conforme vc disse:
