Hi,

I used Hibernate 2.0.3.

I have an exception on the method

line 25 : SessionFactory sessions = cfg.buildSessionFactory();

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException

I have an Table with a one-to-many assocaition on a AssociationTable


The Table have one primary key
The AssociationTable have a composite primary key

see mapping :

My Table with the one-to-many association
<?xml version="1.0"?>

In the method
net.sf.hibernate.sql.OracleJoinFragment.addJoin(...)
I have display the size of the fkColumns and the size of the pkColumns and i obtain
this :

fkColumns.length = 2 and pkColumns.length = 1

and i have display the values :

FK 0 labeled_0_.LABELED_EXTRACT_ID
FK 1 labeled_0_.CTRL_ELT_ID
PK 0 LABELED_EXTRACT_ID

If i remoce the one-to-many association in my table mapping file my script run correctly

Do you have any idea ?

Thank you for your help.

Hmmmm. we have seen this a few times recently.

The mapping -looks- ok.

Perhaps I broke something in 2.0.3.

Could you submit your mappings + persistent classes to JIRA please? I'll look into this.

How can I submit my files in the jira ?

I create a new issue of type bug or other ?

Thanks

create a new bug. I'm not convinced its really a bug, but thats the suspicion.

It's ok

Bug number HB-431 with a tar.gz of my files

Thank you for your help.

Guillaume

The problem was that you had two <one-to-one> mappings from a class with a composite id to a class with a single <id> column. This is obviously incorrect. When I removed these, the mappings compiled correctly.

I also noticed that Hibernate 2.1 throws a friendlier exception, which is good.

Now, notice that the real problem had nothing to do with the mappings you posted here. Please ALWAYS ISOLATE porblems before posting!

Thank and I am sorry for my mistake !
