Iam using a idgenerator class to generate id to the corresponding argument, That means this idgenerator class contains getNextid(String tableName) , The tableName argument may be "sales" or "purchase";
If we gave "sales" to getNextid it will return next value.

Table look like
idgenerator
id table_name value

1 sales 12
2 purchase 5

So if we call getNextid with "sales" argument it will return 13, i think u got the idea.

I need to used it in hibernate mapping file (sales.hbm.xml)'s <id> section

Wow can i do this ? which generator is used for that ? please give me some advice .. thanks to all[/list]

I think there is something in the doc about this :


Your class generating codes have to implement org.hibernate.id.IdentifierGenerator. So you can use it after in the mapping...
