I installed hibernate tools eclipse plugin recently, so I have one question about it:

How can I add another DAO exporter. I want to use two exporters for dao , each using it's own template.

thanx!

Use Ant to generate your code using two <hbmtemplate> tasks. Here is an old piece of my build (I don't generate DAO's anymore, use base class and Spring to configure specific entity DAO's). Hope this gives you a place to start.

Code:
   <!-- ================================================================
       target: dao
         The target to generate the DAO interface and implementation
         classes. note that the hibernate configuration file must
         have already been generated/supplied
       ================================================================ -->
   <target name="dao" depends="init" description="Generate the DAO interface and implementation classes">
      <echo message="***** Building the DAO interface and implementation files... *****"/>
      <hibernatetool>
         <configuration configurationfile="${dir.javasource}/hibernate.cfg.xml"/>
         <hbmtemplate
            templatepath="${dir.template.dao}"
            template="${dao.intf.templatename}"
            destdir="${dir.dest.dao.interface}"
            filepattern="${dao.intf.filepattern}">
            <propertyset refid="dao.properties"/>
         </hbmtemplate>
         <hbmtemplate
            templatepath="${dir.template.dao}"
            template="${dao.hibernate.templatename}"
            destdir="${dir.dest.dao.hibernate}"
            filepattern="${dao.hibernate.filepattern}">
            <propertyset refid="dao.properties"/>
         </hbmtemplate>
      </hibernatetool>
      <sequential>
         <echo message="***** ...DAO interface and implementation files sucessfully generated, refreshing... *****"/>
         <antcall target="refresh"/>
         <echo message="***** ...DAO interface and implementation file generation complete! *****"/>
      </sequential>
    </target>

Thanx, I configured ant task and it works, but it throws exception:
Interesting thing is that code is generateed successfully. I don't understand why exception is thrown

Here is the stack:

I can't figure out how you can have a PersistentClass without an entityName. That's an odd one. Do you have any non-straightforward mappings, i.e. Component, Subclassing?

Yes, I have subclassing. You think this could be the problem?

Definitely could be. I've had problems with my inheritance mappings (table-per-class-hierarchy) in the reverse engineering tools, and usually map my subclasses by hand.

Thanx, you helped me a lot.
I will ignore this exception for now, since code is generated properly.

don't ignore it; it will stop any subsequent code generation - it's probably caused by you calling entityName on something that is a component (not an entity).

But, how can I solve this.
I think it fails on one-to-many or many-to-one mappings.

here is the mapping on which this exception occures:

Code:
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
    "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
    "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

<hibernate-mapping default-lazy="false">

   <class name="hr.ib.webframework.site.Page" table="ib_page">

      <id name="id" type="java.lang.Long">
         <column name="ib_id" not-null="true" />
         <generator class="native" />
      </id>

      <property name="title" type="string" column="ib_title" length="255" not-null="false" />
      <property name="keywords" type="string" column="ib_keywords" length="1000" not-null="false" />
      <property name="description" type="string" column="description" length="1000" not-null="false" />
      <property name="url" type="string" length="255" not-null="true" />
      <property name="view" type="string" column="ib_view" length="255" not-null="false" lazy="false" />

      <many-to-one name="parent" class="hr.ib.webframework.site.Page" column="ib_parentpage" not-null="false" />

      <list name="children" cascade="all" lazy="true">
         <key column="ib_parentpage" />
         <index column="ib_index" />
         <one-to-many class="hr.ib.webframework.site.Page" />
      </list>

      <list name="modules" cascade="all" lazy="true">
         <key column="ib_page_id" />
         <index column="ib_index" />
         <one-to-many class="hr.ib.webframework.site.modules.BasicModule" />
      </list>


   </class>

</hibernate-mapping>
