Jboss CMP2 with Oracle8
Carro
succeed to make to work correctly a simple entity bena CMP
The code generated automatically from the container for the finder by
primary key is not correctly ended. Why?
My table is:
CREATE TABLE egor.Version
(
ID NUMBER(10) NOT NULL,
DESCRIZIONE VARCHAR2(255) NOT NULL,
CONSTRAINT PK_TEST1 PRIMARY KEY (id)
);
This is JBOSS log
