[sorry for my english]
I use JPA/Hibernate (standart version in JBoss 5.1.0) on old database (Oracle 10g).
In this database used ID type NUMBER(38) (and exists ID more 10^20).

Id Entity I need use BigInteger.

1. Why used org.hibernate.id.SequenceHiLoGenerator for @GeneratedValue(strategy = GenerationType.SEQUENCE) ? SequenceGenerator work correct.

2. Why SequenceHiLoGenerator can not work with BigInteger?

3. is this going to be fixed?

PS: TopLink correct work with BigInteger.
PPS: where I can see version of Hibernate in jboss?

Hi all, I have the same problem:

@SequenceGenerator(name = "seq", sequenceName = "sequence")
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "seq")
@Column(name = "XXX", nullable = false, length = 20)
BigInteger ix;
...}

Does not work (ix is always null). Changing BigInteger to Long works.

Any advice?

I am using Hibernate 3.6.1.Final

works fine with

BigInteger ix = new BigInteger("0");
