I am not sure whether my question is offtopic, it is about "how to generate the <property> inside <composite-element> with xDoclet" ?
Example:


I want to generate <property> and <many-to-one> using xDocle,

For now, i use something like this:

After that, i manually add back <property> and <many-to-one> to the .hbm.xml.

It seems that xDoclet does not support nested <property>.

Any hints are great~!

Hmmm. I'm not 100% sure. I would have _expected_ it to work if you have @hibernate.property tags on the composite element class.

Oh, i have tried that, not successful. It will generate the unwanted .hbm.xml

I do think all the tags should be placed in the parent class, just below the


So maybe xDoclet does not support it.

no, no. it won't generate an unwanted mapping unless you also specify an @hibernate.class!

And nah, I don't think the tags should go in the parent class. They should go on the composite element class.

We might just be missing a line from the XDoclet tempate or something. Or perhaps you are still doing something wrong.


(I don't have an xdoclet checkout on my new laptop yet.)

Note, this should all work the same for composite-elements as it does for components (which DOES work, I know for sure).

Try adding a column attribute to the composite-element tag:



I think you will need this so Hibernate will know what column ties a Foo to a Bar in the M-N relationship.

Good luck.

Oops. By code was from the Hibernate generic example, but I think you get my point.

The documentation is wrong.

The tag should be @hibernate.collection-composite-element.

Ah yes. I forgot about this. This is a bug in the lasest beta of XDoclet 1.2. Here is some more details on this:

Finally worked..

What Gavin suggested is absolutely correct.
Specify something like

for the extra foreign keys in the composite-element class..

Or specify something like
for the extra property in the composite-element class.

Do not add stupid things like @hibernate.class or @hibernate.id, everything will work.

Also, remember to provide getters for all the FK and Properties!

Geek,

Could you post a full example that shows how you got this to work? I'm having the exact same problem and I can't figure it out. I've tried doing everything suggested above but I'm probably missing something stupid.

Thanks,

I think it would be good to have a contrib page showing the various ways to map XDoclet tags including some of the more advanced features.

I am also coming across such a problem. I do eager the contrib page can be built as soon as possible!
