How to define an non-JTA datasource for JPA-Hibernate? org.hibernate.connection.DatasourceConnectionProvider - Could not find datasource:

Question

Hi all,

I am trying to change my web-app's JDBC code to JPA using Hibernate as provider. I am using Eclipse IDE. In that i have defined a MySQL data source. I added it in the persistence.xml. But, I am getting the below error.

6640 [30289364@qtp-7494106-7] ERROR org.hibernate.connection.DatasourceConnectionProvider  - Could not find datasource: tamSql
javax.naming.NameNotFoundException; remaining name 'tamSql'

My persistence.xml looks like,

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"&gt;
<persistence-unit name="ExpensePersistentUnit" transaction-type="RESOURCE_LOCAL">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<non-jta-data-source>tamSql</non-jta-data-source>
    <class>com.pricar.JPAInteg.Role</class>
    <class>com.pricar.JPAInteg.User</class>
    <class>com.pricar.JPAInteg.Userdetail</class>
    <class>com.pricar.JPAInteg.Category</class>
    <class>com.pricar.JPAInteg.Expens</class>
    <class>com.pricar.JPAInteg.Leavetable</class>
    <class>com.pricar.JPAInteg.Permissiontoken</class>
    <class>com.pricar.JPAInteg.Roletokenassociation</class>
    <class>com.pricar.JPAInteg.UserPK</class>
<properties>
    <property name="hibernate.connection.url" value="jdbc:mysql://localhost/officemgmt"/>
    <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect"></property>
    <property name="hibernate.connection.driver_class" value="com.mysql.jdbc.Driver"/>
    <property name="hibernate.connection.password" value="1234"/>
    <property name="hibernate.connection.username" value="root"/>
    <property name="hibernate.hbm2ddl.auto" value="update"/>
    <property name="hibernate.show_sql" value="true"/>

</properties>

Any Suggestions!!! Thanks in Advance!

You don't need <non-jta-data-source> when your datasource is configured in <properties>. <non-jta-data-source> is needed when datasource is configured in application server configuration and obtained via JNDI.
