hi all,

i have to add a property to my persistent class at runtime. is there any sample which would help me to use the PersistentClass.addProperty method.

thanks

// Get the existing mapping for User from Configuration
PersistentClass userMapping = cfg.getClassMapping(User.class);

// Define a new column for the USER table
Column column = new Column();
column.setType(Hibernate.STRING);
column.setName("Krishna");
column.setNullable(false);
column.setUnique(true);
userMapping.getTable().addColumn(column);

// Wrap the column in a Value
SimpleValue value = new SimpleValue();
value.setTable(userMapping.getTable());
value.addColumn(column);
value.setType(Hibernate.STRING);

// Define a new property of the User class
Property prop = new Property();
prop.setValue(value);
prop.setName("Krishna");
userMapping.addProperty(prop);
// Build a new session factory, using the new mapping
SessionFactory sf = cfg.buildSessionFactory();


Hope I am making sense.

hi

i did as u said but now the issue is that my .cfg.xml contains only the id (primary key) and the rest of the column property, i am adding programmatically as you said.

but when i try to save the values in the table by calling session.save, it picks only the id and not the columns.

it creates the query as

insert into teams (TEAM_ID) values (?)

whereas it should create as

insert into teams (TEAM_ID, TEAM_NAME) values (?,?)

(Here TEAM_ID is present in xml and TEAM_NAME, i am adding through configuration)

please let me know what am i missing out. its very urgent.

Thanks

any clue for the above problem. it is urgent.

the above issue was resolved.

but now a new requirement:
I need to add the associations also dynamically just like the way the peoperty was added (as mentioned above). Where can i get some samples for the same.

Thanks

Hi all,
