I'm trying to persist a simple object to a MySql database...

My Hibernate.properties...

Quote:
hibernate.connection.username=root
hibernate.connection.password=secret
hibernate.connection.url=jdbc:mysql://localhost/j2tutos
hibernate.connection.driver_class=com.mysql.jdbc.Driver
hibernate.dialect=net.sf.hibernate.dialect.MySQLDialect
hibernate.show_sql=true


My Mapping File (which matches) my object...

Quote:
<hibernate-mapping>
<class name="net.sourceforge.j2tutos.business.products.Product" table="products">
<id name="key" column="id">
<generator class="identity"/>
</id>

<property name="name" column="name"/>
<property name="version" column="version"/>
<property name="description" column="description"/>
<property name="desc1" column="desc1"/>
<property name="desc2" column="desc2"/>
<property name="state" column="state"/>
<property name="path" column="path"/>
<property name="price" column="price"/>
<property name="cost" column="cost"/>
<property name="currency" column="currency"/>

</class>

</hibernate-mapping>


My Java Code...

Quote:
public Result persist(PersisterParm parm) {
HibernatePersisterParm hbmParm = null;
Result result = Result.getDefaultResult();

if (parm instanceof HibernatePersisterParm) {
hbmParm = (HibernatePersisterParm) parm;
try {
getCofiguration().addClass(hbmParm.getClazz());
Session session = getSessionFactory().openSession();
session.saveOrUpdate(hbmParm.getObject());
session.flush();
session.close();
} catch (HibernateException hbe) {
result.setSuccessful(false);
result.addErrorMessage(hbe.getMessage());
}
} else {
result.setSuccessful(false);
}

return result;
}



My result...

Quote:

Best I can tell my Product class and the mapping match. I'm also sure that my object is not null when passed into my method.

Any help apprecieated.

TIA,

Happy

Looks like there is nothing bad in code, tryto find problem with debuger, it can be caused by class loading in IDE.

Error happens here:

Quote:
session.saveOrUpdate(hbmParm.getObject());


And all I get back is an (Mapping) Exception with the following message:

Quote:
No persister for: net.sourceforge.j2tutos.business.products.Product


Any way to turn on finer debugging in Hibernate?

Hi,

Usually hibernate will follow whatever log4j settings you have. So if you put a line :

log4j.logger.net.sf.hibernate=DEBUG

in your log4j.properties Hibernate will print out all debugging statements.

Well, from the log, it looks like you call buildSessionFactory() before you add the mapping to the Configuration.

Yep, that fixed it.

I (wrongly) guessed that the configuration could be altered (mappings added, removed, and/or reloaded) after the SessionFactory had been built....any thoughts as to whether this is/should be possible?

Thanks,

Happy

No! This will never be possible. Hibernate performs well because we use immutable objects all through the code and never need to do synchronization.
