[Hibernate/Ant] Configuration of Generate basic composite Id

Hi everybody.

On my project i need to generate java classes from an existing data structure. I use Postgres 8.1.9.

The generation must be an automatic task. We generate the entire DB structure and java classes for each production steps.

For this, i use an Ant script to describe the hibernate tools configuration. But i am not able to configure the 'Generate basic composite Ids' check box of the Hibernate tool Eclipse plugin.
All manual generation use this check.And i i change it, all dev must be updated.......this task could be more expensive !

All others parameter are taken in account, except this one. I can't find on internet any links or doc about this parameter. Google gave me only 6 results.

Does any one can help me ?

Hibernate tools: 3.2.0.GA
Name and version of the database you are using: Postgres 8.1.9

Thanks

this is the code used in my and script

Code:

   <hibernatetool destdir="${src.java.dir}">
                   <jdbcconfiguration
                      configurationfile="${hibernate.generate.cfg.file}"
                      packagename="myproject.common.hibernate"
                      detectManytoMany="true"
                      preferBasicCompositeIds ="false"
                      detectOptimisticLock ="true">
                   </jdbcconfiguration>
                   <hbm2java jdk5="true" ejb3="false"/>
                </hibernatetool>

I guess the flag preferBasicCompositeIds is never take in account.

Why ?

Thx

I have many questions !

I try to make a reverse from a structure in Postgres.
I use two way : by eclipse and Hibernante Tool plusgin and by an Ant script.

Same database server, same Hibernate tool version (3.2.0.CR1)

Why the result of generation is different from Eclipse plugin and Ant script ?

Why is there no difference when i change the value of PeferBasicCompositeIds on ant script ?

Why have i Long type for primary key with Eclipse and long with ant ?

Do you need more elements ?
thx

maybe you are using different versions of hibernatetools.jar ?

Maybe you are using different setttings ?
