Hibernate Tools with Ant - annotaions

Hi all,

I am using Hibernate 3 along with the Hibernate Annotations.

Is it possible to use Hibernate Tools with Ant to generate Java code with annotations?

I know that it is possible to do this with Eclipse plugin but I can't find documentation how to do this with Ant.
I ask because I use Idea and not Eclipse and I really don't want to install Eclipse just for this (or maybe I will).

Thanks for any comment and help

Thanks and sorry for asking because this is writen in Hibernate Ant Tools documentation.

Now I tried to run ant task and I have other problems.

org.hibernate.cfg.JDBCBinderException: The type java.lang.Object spans multiple columns. Only single column types allowed for single columns.

I saw many answers for this on forum, but nothing helped.
Problem is that I use Ant with Idea and I can't find solution how to debug ant.
I also run ant with -verbose and this is all I get from output, so I don't know with which table something is wrong and with which column.
I looked at the code from CVS where it is clear that you have fixed that,
but when I built jar and use it I get another problem

I use this build.xml

Code:

<hibernatetool destdir="${basedir}/generated">
    <jdbcconfiguration
        packagename="net.energetika.data"
        propertyfile="hibernate.properties"
        revengfile="hibernate.reveng.xml"/>
    <hbm2java ejb3="true" generics="true" /> <!-- generate default .java files with EJB3 annotations -->
</hibernatetool>

you need to build the tool against H3.1 (should work with the latest release, but if it doesnt then use H3.1 from cvs)

Thanks, it works now!
This new JDBCBinder helped me a lot!

Now I find my bug; I had defined two hibernate.connection.url!
