I have an CMP Entity Bean named Node with parent-child relations to other nodes.
My problem is that when i call the getParent method
the following sql statement is executed:

SELECT parent FROM ttree WHERE (treeid=?)

instead of:
SELECT parentid FROM ttree WHERE (treeid=?)

when i change my table field to use tha name 'parent'instead of 'parentid' everything works great.
how can i map the CMR field 'parent' to table field 'parentid'?

I use JBoss 3.0 RC2

The sql script used to create the db table is:

CREATE TABLE [dbo].[ttree] (
[treeid] [int] IDENTITY (1, 1) NOT NULL ,
[parentid] [int] NULL ,
[datecreated] [datetime] NULL ,
[datemodified] [datetime] NULL
) ON [PRIMARY]

ALTER TABLE [dbo].[ttree] WITH NOCHECK ADD
CONSTRAINT [PK_ttree] PRIMARY KEY CLUSTERED
(
[treeid]
) ON [PRIMARY]
GO

ALTER TABLE [dbo].[ttree] ADD
CONSTRAINT [FK_ttree_ttree] FOREIGN KEY
(
[parentid]
) REFERENCES [dbo].[ttree] (
[treeid]
)
