trying to create cmp correctly(auto-increment);error while running

crazyitguy · Oct 27, 2006

I am using the latest versions of Jboss(4.0.5.GA) and Lomboz(R-3.2-200610201336) along with SQL Server 2005 and Microsoft's SQL Server 2005 JDBC driver.

Lomboz used xdoclet to create the java files based on the SQL table but it did not put anything in the DoctorBean.java file telling it that the primary key was auto-incremented.

Using the JSP files, I can retreive data out of the database fine so I know the connection and drivers are set up properly.

Here is the error:

Code:

Simple Doctor table:

Code:

CREATE TABLE [dbo].[Doctors](
	[DoctorId] [int] IDENTITY(1,1) NOT NULL,
	[firstName] [varchar](50) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL,

 CONSTRAINT [PK_Doctors] PRIMARY KEY CLUSTERED 
(
	[DoctorId] ASC
)WITH (IGNORE_DUP_KEY = OFF) ON [PRIMARY]
) ON [PRIMARY]

Most of DoctorBean.java was createded automatically with xdoclet, I created these items manually but with no success:

I think the EJB is never loaded. I'd check the classpath.

Update:

I changed:
@jboss.entity-command
* name="mssql-get-generated-keys"
to:

* @jboss.entity-command
* name="mssql-fetch-key"

now I get this error when testing the JSP page:

Code:

As the error says, you're inserting a null value in a column where are not allowed: check the query and the values you're retrieving to fulfill it.

Cheers,
Dian

> check the query and the values you're retrieving to fulfill it.
Which query are you talking about?

the column that I am having a problem with is the primary key which is "auto-incremented". I am trying to modify the xdoclet tags to tell jboss not to insert anything into the priamry key.

I think the problem is with my xdoclet tagging......
