Hibernate Tools Version: 3.2.0 GA
Database : Derby 10.3.2.1
Eclipse: 3.3.0
Database: Derby Sample DB (Travel)

I'm able to generate Bean+DAO+Mapping files using hibernate tools.But I'm not able to generate the relation ships among the beans.Means there is no core related to relations in bean/mapping files.

I followed all the steps in the tutorial.
Please help me

Thanks

Hibernate Tools 3.2.0 GA, it's not generating the foreign key constraints in reverse engineering file. Do we need to include this manually into hibernate.reveng.xml?

And I'm running thru choosing the opetion "Reverse Engineering trhu JDBC"

Other wise it's giving ArrayIndexOutofbounce Exception

Is this a bug?

what ArrayIndexOutOfBounds exception ?

with respect to relationships it sounds like the derby driver is not returning consistent metadata.

ArrayIndexOutofbounce exception came when I selected *.* tables (console)
I selected all tables rather *.* now I'm not facing this problem.

And regarding mappings in DAO for Derby ,Derby is not supporting table metadata. So I generated DAOs using mysql (Derby and Mysql is having same sql syntaxes) . So all problems got resolved..

So - reverse engineering derby - at least with relationships in tact - is currently impossible? Is that the consensus?
