Hibernate version: 3.0.2

Mapping documents:3.0

Full stack trace of any exception that occurs:

I have upgraded from hibernate-2.1 to hibernate-3.0.2
now I'm trying to upgrade to new hibernate tools
here is my new build.xml:

Code:

     <target name="hbm2java">

        <taskdef name="hibernatetool" 
   classname="org.hibernate.tool.ant.HibernateToolTask" 
                   classpathref="project.class.path"/>  

        <hibernatetool destdir="${gen-src}" > 
           <configuration  propertyfile="${etc}/hibernate.properties"> 
           <fileset dir="${src}">
   <include name="**/*.hbm.xml" />
           </fileset>
           </configuration>

           <hbm2java/>
         </hibernatetool>

    </target>

I have tried to use "HibernateTools-3.1.0.beta2" and got following exception:

[hibernatetool] (hbm2x.template 94 ) Method getJavaTypeNam
e threw exception for reference $pojo in template pojo/PojoFields.vm at [10,37]

now when I try to use "hibernate-tools-3.1.0.alpha5" it works, but
for my id define as:

Code:

I get generated "Long" instead of "long",

1. why is that?

2. also, in hibernate-tools 2 I could define the following

Code:

hbm2java config="${build-src}/codegen.cfg.xml" output="${gen-src}"

which allowed me to use codegen.cfg.xml and define meta tags, now I don't see anywhere in the doc on how to do that.

3. Also tried "hibernate-tools-3.0.0.alpha4a", but here I'm getting
java.lang.ExceptionInInitializerError

PLEASE HELP!!!

Could not res
olve type without exception for org.hibernate.mapping.Property(parameters) Value
: org.hibernate.mapping.Array(com.crossbeamsys.nms.task.TaskDO.parameters)

so you haven't specified type for the com.crossbeamsys.nms.task.TaskDO.parameters - fix that.

the cfg.xml option is not available anymore, put the <meta> names in the top of your hbm.xml files.

well,

nothing has changed since I've done an upgrade
and it worked fine before.
the type attribute is not even listed for this type def:

it should be of type "com.test.task.TaskParameter"

and what's also wierd is that if I use "hibernate-tools-3.1.0.alpha5" it build fine, but in place of "com.test.task.TaskParameter" I get null
like this: "private null[] parameters;"

Code:

        <!-- The parameters property -->
 <array name="parameters" table="taskParametersTable" cascade="all">

            <key column="taskId"/>
            <index column="hibernateIndex" type="int"/>

           <composite-element  
                class="com.test.task.TaskParameter">

                <!-- The parameter name property -->
                <property name="name" type="string" length="80" not-null="true">
                    <meta attribute="field-description">
                        The parameter name.  This name will be understood by the 
                        Task Execution MDB.
                    </meta>
                </property>

                <!-- The parameter value property -->
                <property name="value" type="string" length="80" not- 
                        null="true">
                    <meta attribute="field-description">
                        The parameter value.
                    </meta>
                </property>
            </composite-element>
        </array>

what am I missing here?
