I am using hibernate 2.1.3, generating classes from a db with middlegen and hbm2java. I have 2 questions related to its usage.

First, I am wondering how to tell the TypeMapper to use primitive types for my ids (int instead of java.lang.Integer), and second I was wondering if it is possible to set the id generation type somewhere in the middlegen or hbm2java tasks. I would like set the generation type to hilo instead of assigned.

Thanks.

<middlegen
appname="${name}"
prefsdir="${conf.dir}"
gui="${gui}"
databaseurl="${database.url}"
driver="${database.driver}"
username="${database.userid}"
password="${database.password}"
schema="${database.schema}"
>

<table name="tblAddress" singular="Address" plural="Addresses" />

<!-- skip a few (I have 60+ tables listed here)-->

<table name="tblUserRole" singular="UserRole" plural="UserRoles"/>
<table name="tblWebFile" singular="WebFile" plural="WebFiles"/>

<!-- Plugins -->
<hibernate
destination="${gen-src.dir}"
package="com.${name}.gen"
genXDocletTags="true"
javaTypeMapper="middlegen.plugins.hibernate.HibernateJavaTypeMapper"
/>

</middlegen>

<!-- HBM2JAVA-->
<target name="hbm2java" depends="middlegen"
description="Generate .java from .hbm files.">
<taskdef

Hi,

1) It best not to use primitive type for primary keys hence why the Mapper have been created this way. You can manually change the type using the GUI or you can edit the preferences file. Another option is to write you own java type mapper. This was designed so that you can build you own type associations which is what you have asked.

2) The generator type can be set using the GUI. In the current CVS version (I hope to do a release soon) you can set the generator type but its restricted to only 'assigned' or 'native'. In your case it might best best to edit your preferences file appropriately.

Hope this helps.
