after to see some threads i have this configuration
(remember that i work with Hibernate and jdbc)

i have only 2 context for configuration for the db

One: for general db connection

<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">							 
        <property name="driverClass">
            <value>com.mysql.jdbc.Driver</value>
        </property>
        <property name="jdbcUrl">
		<value>jdbc:mysql://localhost:3306/mydb</value>
        </property>
        <property name="user">
            <value>someuser</value>
        </property>
        <property name="password">
            <value>somepassword</value>
        </property>
        <property name="acquireIncrement">
            <value>3</value>
        </property>
        <property name="minPoolSize">
            <value>6</value>
        </property>
        <property name="maxPoolSize">
            <value>26</value>
        </property>
        <property name="maxStatementsPerConnection">
            <value>100</value>
        </property>
        <property name="idleConnectionTestPeriod" >
            <value>3000</value>
        </property>
        <property name="automaticTestTable">
            <value>c3p0_test_table</value>
        </property>
        <property name="numHelperThreads">
            <value>20</value>
        </property>
    </bean>

Two: for hibernate

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
	<property name="dataSource">
		<ref bean="dataSource"/>
	</property>
	<property name="mappingResources">
		<list>a lot of hhm files </list>
	</property>
	<property name="hibernateProperties">
		<props>
        	<!-- SQL dialect -->
		<prop key="hibernate.dialect">org.hibernate.dialect.MySQL5InnoDBDialect</prop>

                <!-- JDBC connection pool (use the built-in) -->
		<!-- <prop key="hibernate.connection.pool_size" >1</prop>  -->

		<!-- Enable Hibernate's automatic session context management -->
		<prop key="hibernate.current_session_context_class" >thread</prop>

		<!-- Disable the second-level cache  -->
	 	<prop key="hibernate.cache.provider_class" >org.hibernate.cache.NoCacheProvider</prop>

		<!-- Echo all executed SQL to stdout -->
		<prop key="hibernate.show_sql" >true</prop>			
					
		<!-- Drop and re-create the database schema on startup -->
 		<prop key="hibernate.hbm2ddl.auto" >create-drop</prop> 

<!-- 
		<prop key="hibernate.c3p0.min_size" >5</prop>
		<prop key="hibernate.c3p0.max_size" >20</prop>									<prop key="hibernate.c3p0.timeout" >300</prop>
		<prop key="hibernate.c3p0.max_statements" >50</prop>							<prop key="hibernate.c3p0.idle_test_preriod" >3000</prop>
 -->										
	     </props>
      </property>
</bean>   

<bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
		<property name="sessionFactory">
			<ref bean="sessionFactory"/>
		</property>
</bean>				
<bean id="hibernateInterceptor" class="org.springframework.orm.hibernate3.HibernateInterceptor">
   	     <property name="sessionFactory">
        	   <ref bean="sessionFactory"/>
         	</property>
</bean>

so pls, what is wrong in my configuration???
i think that our members has the correct configuration

thanks for advanced
