Body:
The problem is that till 1.2.1 you would set "string" or "integer" for the id's
'type' parameter(as described as in hibernate's document), now, you'll have to
set "java.lang.String" for "string" and "java.lang.Integer" for "integer" and
so on, or just don't set it at all.
Probably properties will have this problem too, I don't know cause I stripped
all the 'type' parameters
Well at least that's what was happening with me...
Cya!

Description:
Hi,
This is the first time I've tried using XDoclet with Hibernate and its
spewing out some sort of error when I use it which leads me to believe the
Hibernate plugin has a bug.
I will attach the source-code I am running XDoclet against. Here is the
exception I get when I run XDoclet against it:
com.shadowcraft.desktopbeautifier.Image

Aparently caused by XMethod.getReturnType().getType() returning null which the
hibernate plugin does not expect or handle. I've filed a bug against XJavadoc
against this issue. See
http://opensource.atlassian.com/projects/xdoclet/browse/XJD-44
