Hi!

Can anyone help me? I'm a newbie of Middlegen.

I have an error when I tried to launch <ant hbm2java>

<target name="hbm2java" description="Generate .java from .hbm files.">
<taskdef
name="hbm2java"
classname="net.sf.hibernate.tool.hbm2java.Hbm2JavaTask"
classpathref="lib.class.path"
/>

<hbm2java output="${build.gen-src.dir}">
<fileset dir="${build.gen-src.dir}">
<include name="**/*.hbm.xml"/>
</fileset>
</hbm2java>
</target>

I used Middlegen Hibernate plugin, I added hibernate-extensions-2.1.3
so that Hbm2JavaTask can be recognized. Besides, I imported all
neccessary hibernate jar by the classpath (lib.class.path).
Tools version:
- hibernate-3.0.5
- Middlegen-Hibernate-r5

Thanks in advance.

Your mixing H2 HBM for Hibernate 3.x .
Get the H3 tools jar from the latest Tools download (yes you will have to get the JAR from the package which includes the eclipse plugins).

You could consider moving to Hibernate Tools pack as an alternative.

Thanks for answer ^^

But the latest package Hibernate Tools is a beta version. I think that it isn't stable, not yet. But I'll test it.
If I move to Hibernate Tool pack as an alternative, do I keep the Middlegen tool?

Thanks.

Tim

The package is beta yes but it is quite solid.
You could choose to still use Middlegen (Make sure you set the version attibute to '3.0') and use the H3 tools Ant tools. If you are using eclipse then try out the eclipse hibernate plugins in the package. It has many features which make development easier.

Hi!

I tried out the eclipse hibernate plugins and that works very well! But it generates DAO code that don't enjoy me. For example:
-UserHome whereas UserDao
-some CRUD methods like attachDirty whereas saveOrUpdate.
So I would like to change the template but I don't know where it is and how to change.

Can anyone help me?

Tim

The templates are velocity templates and should be easy to find. You can also substitute your own templates if you wish.
