I want to set my JSF components constraints (length, etc.) via the values in the hibernate configuration files (xxx.hbm.xml).

Anyone familiar enough with Hibernate to explain?

MyEclipse 5.01, Hibernate 3.1

Thanks in advance

Frank

Frank,

You can use Hibernate’s metadata.
For example:

MyPojo pojo = …;
ClassMetadata pojoMetadata = sessionFactory.getClassMetadata(MyPojo.class);

Object[] propertyValues = pojoMetadata.getPropertyValues(pojo);
String[] propertyNames = pojoMetadata.getPropertyNames();
…

See ClassMetadata and CollectionMetadata API for more informations.

Thanks, worked like a charm

Actually, a new rub:

I was able to use the following for normal tables, but it doesn’t work if the configuration is for a view:

    private    void extractMeta(Configuration cfg, Class c, Hashtable ht)
    {
        PersistentClass pcls = cfg.getClassMapping(c.getName());
        
        for(Iterator it = pcls.getPropertyIterator(); it.hasNext();)
        {
            Property p = (Property) it.next();
            
            for (Iterator iter = p.getColumnIterator(); iter.hasNext();)
            {
                Column column = (Column) iter.next();
                
                ht.put(column.getName(), new Integer(column.getLength()));
            }
        }
        return;
    }

Frank,

I suppose that all the view’s columns are included in Hibernate identifier.
The method getPropertyIterator returns only simple properties.
Try to use the method PersistentClass.getPropertyIdentifier.
