I work with JBoss 3.0.4 and Oracle 8.1.6 and I do not
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 TABLETEST1
(
ID NUMBER(10) NOT NULL,
DESCRIZIONE VARCHAR2(255) NOT NULL,
CONSTRAINT PK_TEST1 PRIMARY KEY (id)
);

This is JBOSS log

and my source code:

}
public abstract class TestCmpEntityEJBBean implements EntityBean
{
public EntityContext entityContext;
/* Method for CMP field */
/* ... for primary key */
public abstract Integer getId();
public abstract void setId(Integer id);
/* ... for other CMP field */
public abstract String getDescrizione();
public abstract void setDescrizione(String desc);

public Integer ejbCreate(Integer id, String desc) throws
CreateException
{
/* primary key setting */
this.setId(id);
/* CMP field setting */
this.setDescrizione(desc);
return null;
}
public void ejbPostCreate(Integer id, String description)
{
}
[...]
}
public interface TestCmpEntityEJBHome extends EJBHome
{
/* create has the same signature of ejbCreate in bean class */
TestCmpEntityEJB create(Integer id, String desc) throws
RemoteException, CreateException;
TestCmpEntityEJB findByPrimaryKey(Integer primaryKey) throws
RemoteException, FinderException;
Collection findAll() throws RemoteException, FinderException;
}
 
It is sorta covered in the JavaRanch Style Guide.
