SQLGrammarException: could not load an entity
Hi,
When using JBoss 4.0.5 with Oracle an exception occured while quering a quite complex object from database. Hibernate constructs a query that is not compatible with Oracle: ' select .... from T_COLUMN_TYPE as a14 ..'. It looks like that an other than Oracle9Dialect is taken somewhere.

The following persistence.xml file defines to use Oracle9Dialect.
persistence.xml:
<persistence> <persistence-unit name="tgp"> <jta-data-source>java:/OracleDS_TGP</jta-data-source> <properties> <property name="hibernate.dialect" value="org.hibernate.dialect.Oracle9Dialect" /> <property name="hibernate.hbm2ddl.auto" value="create-drop" /> <property name="hibernate.cache.use_query_cache" value="true" /> <property name="hibernate.show_sql" value="true" /> <property name="hibernate.cache.provider_class" value="org.hibernate.cache.HashtableCacheProvider" /> </properties> </persistence-unit> </persistence>
While deploying the ear a strange sequence of log statements are shown:
"Using dialect: org.hibernate.dialect.HSQLDialect". Later down you can see that Oracle JDBC driver gets inititialized.

I am using JBoss 4.0.5 which comes with EJB3-RC7. When trying RC9 the problem still remains.
Could somebody what's wrong?
