Hello, all!
I have entity bean with attribute "id": Integer wich is primary key.
Catridge for ejb generate for me the following code:
public java.lang.Integer ejbCreate (java.lang.double balance)
throws javax.ejb.CreateException
{
String primaryKey = new java.rmi.server.UID().toString();
setId (primaryKey);
return null; // should not return primaryKey for CMP: see EJB spec,
// chapter 10.5.2 "Bean ProviderТs entity bean instanceТs view"
}
Questions:
1. In compile time I receive error on line:
setId (primaryKey);
(it's obvious, because property "id" has Integer-type, but String)
2. but I have and another problem - I would like to use db-server (and app-server)
vendor specific way for generation of primary key in case Integer or Long primary key.
I mean, for example, sequences for Oracle or autoincrement engine for other db...
How I have to define this?
Thank you.
With best regards,
