Pessoal,

Já pesquisei em diversos lugares fiz diversas alterações nas configurações do meu projeto mas vire e mexe dah aquele erro chato de time out do banco de dados.
Gostaria de saber se tem como eu melhorar a configuração do meu banco.

Segue context.xml

<?xml version="1.0" encoding="UTF-8"?>
<Context>
	<!-- ******** BANCO DE DADOS (PRODUÇÃO) ************** -->
	<Resource auth="Container"
		driverClassName="com.mysql.jdbc.Driver"
		initialSize="5" maxActive="100" maxIdle="30" maxWait="10000" minIdle="5"
		name="jdbc/blablabla" 
		type="javax.sql.DataSource"
		url="jdbc:mysql://localhost:3306/blablabla?autoReconnect=true"
		username="user"
		password="senha"
		validationquery="SELECT 1"

		testwhileidle="true" 
		timebetweenevictionrunsmillis="10000" 
		minevictableidletimemillis="60000"
		/>		
			
</Context>

Segue
hibernate.cfg.xml

Creio que possa esta faltando esse trecho de código abaixo:

&lt;context-param&gt;
		&lt;param-name&gt;br.com.caelum.vraptor.provider&lt;/param-name&gt;
		&lt;param-value&gt;br.com.caelum.vraptor.util.hibernate.HibernateCustomProvider&lt;/param-value&gt;
	&lt;/context-param&gt;

	&lt;context-param&gt;
		&lt;param-name&gt;br.com.caelum.vraptor.packages&lt;/param-name&gt;
		&lt;param-value&gt;br.com.caelum.vraptor.util.hibernate&lt;/param-value&gt;
	&lt;/context-param&gt;

Testa e responde ai depois !

fabio.cbrandao 4 de set. de 2012

Vou fazer o teste aqui e respondo.

Obrigado!

Opa, fabio.cbrandao blz ?

Kra, possivelmente seu problemas pode estar na configuração do seu “c3p0”, aumenta seu “c3p0.timeout” de 100 para 3000 e testa ae.

fabio.cbrandao 4 de set. de 2012

a inclusão desse código no web.xml:

<context-param>       
    	<param-name>br.com.caelum.vraptor.packages</param-name>       
        <param-value>   
                 br.com.bronx.vraptor.restrictrex,
                 br.com.caelum.vraptor.util.hibernate
        </param-value>
	</context-param>
	
	<context-param>  
	    <param-name>br.com.caelum.vraptor.provider</param-name>  
	    <param-value>br.com.caelum.vraptor.util.hibernate.HibernateCustomProvider</param-value>  
	</context-param>

começou a me ocorrer o seguinte erro ao fazer o start do server:
