--------------------------------------------------------------
I'd like to run a simple web application with Hibernate4 on a JBoss AS7.
But I have an error below.

java.lang.UnsupportedOperationException: Naming context is read-only

I wrote hibernate.cfg.xml (snippet),

<session-factory name="">
  <property name="connection.datasource">java:jboss/datasources/MySQL</property>
  <property name="dialect">org.hibernate.dialect.MySQLDialect</property>
</sessioin-factory>

and source code: 

Configuration config = new Configuration().configure();
SessionFactory sessionFactory = config.buildSessionFactory(); // It might be causes the error.

I can connect datasouce "java:jboss/datasources/MySQL" use below code.

InitialContext context = new InitialContext();
ds = (DataSource)context.lookup("java:jboss/datasources/MySQL");
conn = ds.getConnection();

Does anyone know the reason for this?
Sorry for my english is poor.
