Using jndi with jpa and spring on glassfish - spring

Question

I have a web application that runs on glassfish 3.1. I am using JPA (Hibernate) configured with spring.
This is my persistence.xml:
<?xml version="1.0" encoding="UTF-8"?>
<persistence 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"
version="2.0">
<persistence-unit name="myPU">
<class>org.myCompany.entities.Class1</class>
<properties>
<property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5Dialect" />
<property name="hibernate.show_sql" value="true" />
</properties>
</persistence-unit>
</persistence>
This is part of my ApplicationContext.xml:
<tx:annotation-driven />
<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager"
p:entityManagerFactory-ref="entityManagerFactory" />
<bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName" value="jdbc/myDataSource" />
</bean>
<bean id="entityManagerFactory"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="persistenceUnitName" value="myPU" />
<property name="jpaVendorAdapter">
<bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
<property name="databasePlatform" value="org.hibernate.dialect.MySQL5Dialect" />
</bean>
</property>
</bean>
In addition i have declared my datasource in the glassfish server (jdbc connection pool and recourse)
and the JNDI name is "jdbc/myDataSource". The issue is that on my local installation of glassfish, published via the glassfish plugin for eclipse, it works fine BUT when i deploy the war file manually on an installation of glassfish (i tried on my VPS - CentOS) then i get this error:
Error occurred during deployment: Exception while preparing the app : Exception [EclipseLink-4002] (Eclipse Persistence Services - 2.3.2.v20111125-r10461): org.eclipse.persistence.exceptions.DatabaseException Internal Exception: java.sql.SQLException: Connection could not be allocated because: java.net.ConnectException : Error connecting to server localhost on port 1527 with message Connection refused. Error Code: 0. Please see server.log for more details.
For some reason, the application is using the default derby datasource of glassfish and not my defined datasource. anyone knows why and how to overcome this?

Answer 1

Did you configure your JDBC Resource to use the right Connection Pool? There is a default derby pool configured. Maybe you just selected the wrong pool for your resource?
