Hibernate Tools: Error parsing JNDI name

Question

We are trying to upgrade from Hibernate 3.6.7 to 4.1.2 and Hibernate Tools 3.2.0 to 3.5.0

We generate a DB creation script using Ant:

     <hibernatetool destdir="${target}">
        <jpaconfiguration persistenceunit="stdcmpOrderPersistenceUnit" propertyfile="@{propertyfile}"/>
        <classpath refid="@{classpathid}"/>
        <!-- the file name is relative to $destdir -->
        <hbm2ddl outputfilename="@{output}" format="true" export="false" drop="false"/>
     </hibernatetool>

Our persistence unit look like this:

<persistence-unit name="stdcmpOrderPersistenceUnit" transaction-type="JTA">

    <provider>org.hibernate.ejb.HibernatePersistence</provider>
    <jta-data-source>jdbc/lakshmi_stdcmp</jta-data-source>
    <mapping-file>META-INF/stdcmpOrderNamedQueries.xml</mapping-file>

    <class>ch.ethz.id.wai.lakshmi.stdcmp.persistency.PersistentOrder</class>

    <exclude-unlisted-classes>true</exclude-unlisted-classes>

    <properties>
        <property name="hibernate.show_sql" value="false"/>
        <property name="hibernate.format_sql" value="false"/>
    </properties>

</persistence-unit>

After the upgrade we get the following error:

[hibernatetool] org.hibernate.service.jndi.JndiException: Error parsing JNDI name [jdbc/lakshmi_stdcmp]
[hibernatetool] javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file:  java.naming.factory.initial

Why does Hibernate try to resolve the JNDI name since all the information on the PersistenceUnit is available? We had no problems with the old version.

And in any case how can we specify a NamingFactory? (and which one?)

Answer 1

I was having a similar problem, specifically causing the "Error parsing JNDI name", and it was easily fixed by simply removing the empty name attribute from the session-factory tag.

My hibernate.cfg.xml had

<session-factory name="">

This was auto-generated, so I just removed the name attrib.
