Ant and hbm-Metainformation

Hi there,

I'm pretty new to hibernate.

I would like to know what variables representing hbm-metainformation are available in the ant-task "hbmtemplate".
In the docs i only found "class-name" and "package-name".

In this Ant-task I require the value which returns ${pojo.getShortName()} in my Template.

Any ideas?
Thanks in Advance.

class-name and package-name is for the filepattern.

all of the rest are very much used in the templates and doesn't ${pojo.getShortName()} work for you in your template?

Hi,

the problem is, that i want to use my hibernate-pojos as base-classes (eg. mydomain.model.PersonBase) and extend them with classes like mydomain.model.Person for implementing specific issues.

Hibernate-Mapping

Code:

<hibernate-mapping>
    <class name="Person">
      <meta attribute="generated-class">mydomain.model.PersonBase</meta>
        <id name="id" type="int">
            <generator class="native"></generator>
        </id>
        <property name="name" type="string"></property>
    </class>
</hibernate-mapping>

Ant-Task

Code:

<target name="hibernate-pojos" >
    <hibernatetool destdir="${src}">
    <configuration configurationfile="src/hibernate/hibernate.cfg.xml"/>
           <hbm2java/>
       </hibernatetool>
</target>

--> this outputs mydomain/model/PersonBase.java

Up to now everything is fine.
Now I want to generate the sublass Person from following template PojoSubclass.ftl.

Template

Code:

${pojo.getPackageDeclaration()};

public class ${pojo.getShortName()} extends ${pojo.getDeclarationName()}
       implements java.io.Serializable {

    /** default constructor */
    public ${pojo.getShortName()}() {
    }
}

...with Ant-Task

Code:

<target name="hibernate-subclass-pojos" >
   <hibernatetool destdir="${src}">
       <configuration configurationfile="src/hibernate/hibernate.cfg.xml"/>
          <hbmtemplate
           filepattern="{package-name}/{class-name}.java"
           template="PojoSubclass.ftl"
          />
       </hibernatetool>
   </target>

Now I have the problem, that the extended class will be named as the superclass (PersonBase) and overwrites it. So i need an expression in filepattern which represents "Person" and not "PersonBase" (like {class-name} does).

for your specifc case you could just do:

Code:

filepattern="{package-name}/{class-name}Base.java"

if you look in the jira there is a issue we need to solve that is about this exact issue.

We probably need to evaluate the filepattern "inside" the same template context allowing you to use freemarker syntax.
