Thank you very much. I've lost a lot of time to find this :). I'm new
popular with so poor documentation. It's very frustrating. I post the
received no answer. Usually the open source framworks are poor, but
existent. The JBoss was similar, and hibernate is a JBoss splinter.

Hi!
I need to get the associated class name and attribute name having
table_name and column_name.
I have the Hibernate mapping file:
<hibernate-mapping>
<class name="com.esi.masterlist.model.EsiPharmMaster"
schema="HSTANCIU" table="ESI_PHARM_MASTER">
<id name="esiphmDemSk" type="java.lang.Long" column="ESIPHM_DEM_SK"
length="22">
<generator class="native">
</generator>
</id>
<property name="aqppExceptionG34sk" type="java.lang.Long"
column="AQPP_EXCEPTION_G34SK" length="22"/>
</class>
</hibernate-mapping>
I need to get at runtime from the table_name (ESI_PHARM_MASTER) and
column_name (AQPP_EXCEPTION_G34SK) the object class
(com.esi.masterlist.model.EsiPharmMaster) and property name
(aqppExceptionG34sk).
THank you,
Horatiu
Map x =
HibernateSessionFactory.getSessionFactory().getAllClassMetadata();
for (Iterator i = x.values().iterator(); i.hasNext(); ) {
SingleTableEntityPersister y = (SingleTableEntityPersister)i.next();
System.out.println(y.getName() + " -> " + y.getTableName());
for (int j = 0; j < y.getPropertyNames().length; j++) {
System.out.println(" " + y.getPropertyNames()[j] + " -> " +
(y.getPropertyColumnNames(j).length > 0?
y.getPropertyColumnNames(j)[0]: ""));
}
}
That will show you all the tables that go with all the classes in your
schema and all the class properties that go with columns in your
tables.
You can search through that or pre-load a more searchable structure
depending on your performance requirements.
