Hi!
Lets say I have an hbm like this:

<class
name="mx.lania.extranet.domainmode.Group"
table="groups"
>
<id
name="id"
type="int"
column="id"
>
<generator class="sequence">
<param name="sequence">group_id_seq</param>
</generator>
</id>
<property
name="name"
type="java.lang.String"
column="name"
not-null="true"
length="50"
/>

</class>

It will normally generate a somewhat class like this:

public class Group implements Serializable {

public Group() {
}

public java.lang.Integer getId() {
return this.id;
}

public void setId(java.lang.Integer id) {
this.id = id;
}

public java.lang.String getName() {
return this.name;
}

public void setName(java.lang.String value) {
this.name =value;
}
}

but I want it to generate 2 class, one with de persisten propeties (an or relationships) and another, for me to write my particular bussines logic:

//In SuperGroup.java
public class SuperGroup implements Serializable {

public BaseGroup() {
}

public java.lang.Integer getId() {
return this.id;
}

public void setId(java.lang.Integer id) {
this.id = id;
}

public java.lang.String getName() {
return this.name;
}

public void setName(java.lang.String value) {
this.name =value;
}
}

//In Group.java
public class Group extends SuperGroup {
}

This way, i can regenerate my .java very every time that i feel like it
without the risk of loosing my custom bussines logic (yes, I know i can marge, and restore old CVS versions of my work, but this way it would be SO much easier, I miss http://www.rubicode.com/Software/EOGenerator/ from my EOF times) if this is not supported I think i shouldt be so hard to do it, if someone gives me some hits about what classes/methods in hbm2java i have to modify I'd be glad to contribute this back to the community.

EOGenerator is a command-line tool for generating Java and Objective-C EO classes from EOModel file(s) using a different method than Apple's EOModeler. Two classes are generated for each EOEntity: one that is generated every time the EOEntity changes, and a subclass (the real EO class) that is only generated once. This approach allows business logic to be implemented in the subclass without fear of being overwritten later.

When using customized templates, it is possible (among other things) to generate methods to call fetch specifications, generate methods to add and remove objects from relationships with typed arguments, to have a custom superclass for all your EOs, and generate cross-framework #import statements correctly for Objective-C classes when models are in separate frameworks. Example templates are provided for Java and Objective-C that show some of these additional abilities.

EOGenerator can be compiled and used on MacOS X 10.x, MacOS X Server 1.2, WebObjects/NT, and OPENSTEP. It comes with source code. EOF or WebObjects is also required.

Is something like this possible with hbm2java?
bye, thanks

geezz...people just don't read the docs ;(

This is the THIRD time today i say the following:

Read the docs about the meta tag in the docs.

Look at <meta attribute="generated-class"> which allows exactly this.

You only add it on a "need-to-extend" basis....avoiding extra classes if not needed.

You then just make it generate an abstract calss which you extend...

Yes, it is in Page 126 in the hibernate_reference.pdf it says:
generated-class
generated-class overrule the name of the actual class generated
I am sorry, I just i didn't think that I could use it for this... on the other side th disadvantage is that i use MiddleGen to generate de .hbm, and I am going to have to customize them by hand (it would be nice to be able to do this automagically ;)

don't the new middlegen support arbitrary meta tags on stuff, or is it just a few specifics it knows ?

David ?

Hi!
"From release 3 of the plugin XDoclet markup can be generated using meta tags in the hbm mapping document." (http://www.hibernate.org/98.html) but I found nothing about the metatag that I need :'(
Anyone working on this?
