Hello,
I have created three new tables in my database.
Code:
Table climate_classification
============================
I_GROUP, I_LNG, C_LBLCLS
----------------------------
I_GROUP int(11) PK
I_LNG int(11) PK
C_LBLCLS varchar(25)
Table climate_coordinate_bkp
============================
R_LAT, R_LGT, C_CLS
----------------------------
R_LAT double(9,7) PK
R_LGT double(10,7) PK
C_CLS varchar(3) PK
Table climate_group
===================
C_CLS, I_GROUP
-------------------
C_CLS varchar(3) PK
I_GROUP int(11) PK
So I have one table climate_classification listing main climate groups (from köppen), one table climate_group listing the "sub" climates et one table climate_coordinate setting the area of the "sub" climates.
I have define I_GROUP of my table climate_classification as foreign key for climate_group and I have also define C_CLS of my table climate_coordinate as foreign key from climate_group.
When I try to generate (reverse engineering) mapping files hbm and JAVA classes using Hibernate Tools for Eclipse (Version: 3.4.0.v20110215-1252-H31-GA) I got the following error:
Code:

What is the problem? where is it coming from?
thank you for your help.
