 Post subject: Schemaexport - DataSource problem with WLS8.1

Hi,

I'm using schemaexport with MySQL on WLS8.1SP3

I've used the mapping document below to run the application and it works. I managed to deploy the connection pool and test it on WLconsole. On MySQL log, I can get the test string I specified on the console. It seems the WL side is working ok.

However, when I started to write some POJOs and tried to run schemaexport, I got the stack trace below.

I've tried some properties on hibernate_reference manual,
using < property name="jndi.url">t3://localhost:7001/jdbc/semJDBCDataSource</property>

Modified connection.datasource to java:/comp/env/jdbc/semJDBCDataSource

but none of these works.

Is there some property that I'm missing here? Is it possible to pass the JNDI url to the JNDI initialContext explicitly ( hibernate API says that connection.datasource should suffice )?

Thanks for the reply.

Hibernate version: 3.0

Mapping documents:
Code:
<hibernate-configuration>
   <session-factory name="hibernate_SessionFactory">
      <property name="connection.datasource">jdbc/semJDBCDataSource</property>
                <property name="show_sql">true</property>
                <property name="dialect">org.hibernate.dialect.MySQLDialect</property>
      
        <property name="transaction.factory_class">org.hibernate.transaction.JTATransactionFactory</property>
        <property name="transaction.manager_lookup_class">org.hibernate.transaction.WeblogicTransactionManagerLookup</property>   

                         <mapping resource="Person.hbm.xml"/>
   </session-factory>
</hibernate-configuration>


Full stack trace of any exception that occurs:
Code:

Referring to this link http://www.hibernate.org/120.html#A8, I've modified the mapping document. The link to Mathias' blog is broken so there's no way to read his experience

<property name="jndi.url">t3://localhost:7001</property>
<property name="jndi.class">weblogic.jndi.WLInitialContextFactory</property>

which leads to:

Code:

# ant schemaexport

where my ant target is:

Code:
<target name="schemaexport">
        <schemaexport config="${src.java.dir}/hibernate.cfg.xml"/>


I wonder if the problem described is still present in WLS8.1SP3

Looks like there's nothing wrong with WL's JNDI implementation

when I remove the property jndi.url and jndi.class, I'm able to get the Session from the context

Code:
InitialContext aInitialContext = new InitialContext();
SessionFactory aSessionFactory =
            (SessionFactory) aInitialContext.lookup("hibernate_SessionFactory");

IIRC, there's some old issue with the thread classloader between ant and java.
