[Mahesh Malviya]

Hi,
There is no primary key field in my database table. Is it must to make a PrimaryKey class in developing cmp entity bean.

Thanks and Regards

Yes it is a must to have a primary key, Otherwise how will recognize the entity instance.

If I am not wrong Primary class is must for al Entity beans not just CMP entity beans.

Isn't a primary key a basic part of normalizing tables in a Database anyway? If you have a table with no primary keys, how do you uniquely identify a single row?

Primary Key is a must but primary key class is not. You can certainly have a primary key defined as String...
