<persistence-unit name="default-persistence-unit" transaction-type="RESOURCE_LOCAL">

    <provider>org.hibernate.ejb.HibernatePersistence</provider>
    <class>model.Task</class>

    <properties>
        <property name="javax.persistence.jdbc.driver" value="net.sourceforge.jtds.jdbc.Driver" />
        <property name="javax.persistence.jdbc.url" value="jdbc:jtds:sqlserver://localhost:1433/reports"/>
        <property name="javax.persistence.jdbc.user" value="sa"/>
        <property name="javax.persistence.jdbc.password" value="clubsa"/>

        <property name="hibernate.dialect" value="org.hibernate.dialect.SQLServerDialect"/>
