I am deploying a HAR to JBOSS 4 using Hibernate 2.1.8, I need to enable result set wrapping. This was controlled by
'hibernate.jdbc.wrap_result_sets true' setting in the hibernate.properties.
Looking at the HibernateMBean it doesn't look like there is support
for this config property. Is there any other way (short of hardcoding the
source) to control this?

Currently the JBOSS log states this upon deployment:

Quote:

2005-03-10 11:44:44,264 DEBUG [net.sf.hibernate.cfg.SettingsFactory] Wrap result sets enabled? : false

hibernate-service.xml as follows:

Quote:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE server>

<server>
<mbean code="org.jboss.hibernate.jmx.Hibernate" name="jboss.har:service=VisualDataHibernate">
<attribute name="DatasourceName">java:/VisualDataDS</attribute>
<attribute name="Dialect">net.sf.hibernate.dialect.SQLBaseDialect</attribute>
<attribute name="SessionFactoryName">java:/hibernate/VisualDataSessionFactory</attribute>
<attribute name="CacheProviderClass">net.sf.hibernate.cache.HashtableCacheProvider</attribute>
<attribute name="Hbm2ddlAuto">update</attribute>
<attribute name="ShowSqlEnabled">false</attribute>

</mbean>
</server>

How did you find that undocumented feature?! Why do you think you need it?

As I realize now, I am confusing the (hibernate.properies) setting
with Hibernate3 version. But anyways ... looking at the Loader
under (net.sf.hibernate.loader) you can see that ResultSetWrapper
will be invoked wrapping the JDBC ResultSet given that
session.getFactory().isWrapResultSetsEnabled() is set to true.
The driver I am using generates errors unless I wrap the resultset
and reference the columns by name, also due to driver specific issues
I had to extend the ResultSetWrapper (net.sf.hibernate.impl).

This is why I NEED to enable this setting :)

any ideas?

thanks

p.s. all of this is a part of my ongoing effort to submit a patch to
you guys to support the "amazing" SQLBase and its "great" drivers
