hbm2java errors with hibernate-tools-3

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!!!

I don't seem to be able to find any configuration that works. According to the documentation the below should work, however I get exceptions.

LibraryContext

Build file

Code:

   <path id="project.libs.hibernatetools">
      <fileset dir="libhibernatetools">
         <include name="**/*.jar"/>
      </fileset>
      <filelist dir="D\:\\devtools\\mysql-connector-java-3.1.12">
         <file name="mysql-connector-java-3.1.12-bin.jar"/>
      </filelist>
   </path>

   <target name="hbm2java">
      <taskdef name="hibernatetool" classname="org.hibernate.tool.ant.HibernateToolTask" classpathref="project.libs.hibernatetools"/>
      <hibernatetool destdir="src/generated"> 
         <classpath> <!-- a classpath is optional, but needed for exporters that require access to domain classes etc. -->
            <path location="."/> 
         </classpath> 
         <configuration configurationfile="hibernate.cfg.xml" />
         <hbm2java/>
     </hibernatetool>
  </target>

The exception

Code:

i'm pretty sure you are not using the hibernate that comes with the tools release together with the tools.

using hibernate 3.1 final should work though.

Max,

you were absolutely right. I was using Hibernate 3.1 (12/12/2005) and was ignorant of the fact that the the 3.1.0b2 tools apperantly require 3.1rc3 or newer(the labels '3.1' and '3.1rc3' taken from the jar manifest.

I just combined Hibernate 3.1.1 and verified it works correctly with the 3.1.0b2 Tools. I noticed that the manifest of the tools jar doesn't contain a version. It could be a good idea to make sure the jar manifest version always reflects the exact same version advertised. This would makes it even easier to check which versions I have running in what environmnet.

Thanks again,
Walter

ok, so which hibernate tool should I run with hibernate-3.0.2?

max · **Posted:** Mon Jan 23, 2006 1:07 pm

just the latest. the output of the tools works with any 3.x version.
