Java – using connection pooling in JPA

• Java

I have a standalone JPA (hibernate) - MySQL application

My persistence XML looks like:

<persistence-unit name="JPAProj" transaction-type="RESOURCE_LOCAL">
            <!-- Persistence provider -->
            <provider>
                org.hibernate.ejb.HibernatePersistence
            </provider>
          ....
          <properties>
                    <property name='hibernate.show_sql' value='true'/>
                    <property name='hibernate.format_sql' value='true'/>
                    <property name='hibernate.dialect' value='org.hibernate.dialect.MysqL5InnoDBDialect'/>
                    <property name='hibernate.hbm2ddl.auto' value='update'/>

                    <property name="javax.persistence.jdbc.driver" value="com.MysqL.jdbc.Driver"/>
                    <property name="javax.persistence.jdbc.url" value="jdbc:MysqL://localhost/classicmodels"/>
                    <property name="javax.persistence.jdbc.user" value="someuser"/>
                    <property name="javax.persistence.jdbc.password" value=""/>
           </properties>
     </persistence-unit>

I want to use connection pooling in this application (such as Apache DBCP), and I need to check persistence What changes have you made to XML?
