If my DS name is newsportal under glassfish I just write newsportl in the p.unit. <persistence-unit name="jmagazinePU" transaction-type="JTA">     <provider>org.hibernate.ejb.HibernatePersistence</provider>     <jta-data-source>newsportal</jta-data-source>     <exclude-unlisted-classes>false</exclude-unlisted-classes>      <properties>       <property name="hibernate.connection.useUnicode" value="true"/>       <property name="hibernate.connection.characterEncoding" value="UTF-8"/>       <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect"/>       <property name="hibernate.hbm2ddl.auto" value="none"/>     </properties>   </persistence-unit> Also Where we can copy-paste mysql jdbc driver? Stiil I can not configure DS under JBoss7 and use it with p.unit. Thanks --------------------------------------------------
