Hello,

I have a simple table (Dm_bogus) with two fields, no primary key.

I reverse engineer it with:

<hbm2java ejb3="true"/>

and get 2 files: DmBogus.java and DmBogusId.java. So far so good.
But DmBogus.java is generated with the following annotation in front of id:

@Id(generate = GeneratorType.AUTO)
@Column(name = "CUST_ID")
@Column(name = "TIMESTAMP")
public DmBogusId getId() {
return this.id;
}

Which, of course, doesn't compile:

[javac] C:\umg\java\tools\DmBogus.java:45: duplicate annotation
[javac] @Column(name = "TIMESTAMP")
[javac] ^
[javac] 1 error

I have to remove both @Column's for it to compile.
Is this a bug? Is there a workaround?
Thanks!!!

you have to have a (composite) primary key, ie a way to retrieve a particular row.
In you case the reg eng is not working fine, Check the annotations doc to see how to map a composite PK

Emmanuel,

Thank you for the reply. You say my reverse engineering is not working; I can see that. And my question was, why not? It works fine on the same table when I generate hbm.xml + java. It just doesn't work when I put ejb3="true" in hbm2java.

I've read the part about composite keys you suggested (http://www.hibernate.org/hib_docs/annot ... e/#d0e1128) but it doesn't talk about reverse engineering.

My question was how do I fix reverse engineering so it generates the java file correctly; I KNOW how to fix it manually, but how do I make it work correctly in the first place? If this is not the right forum to discuss reverse engineering and hbm2java, please point me where to ask that question.

Thank you--

Egor
