round trip engineering??

middle gen, generates .hbm files from a datasource. Inside the generated .hbm 
files are xdoclet meta-data tags.

process.
1. generate .hbm from datasource using xdoclet middlegenTask. all of the .hbm 
files now contain 'meta' node(s).
for example:
<class 
    name="com.vanitysoft.griffin.domain.hibernate.Feed" 
    table="feeds"
>
    <meta attribute="class-description" inherit="false">
       @hibernate.class
        table="feeds"
    </meta>

2. run hbm2java using hibernate's xdoclet hbm2javaTask. this creates java class 
files with all of the xdoclet tags(those meta nodes) attached to the approiate 
properties, and classes.

3. (this step is my problem). say i make a change in the xdoclet tag inside of 
my class, and then run xdoclet's own HibernateDocletTask  to re-generate the 
.hbm. the 'meta' nodes are not there!


in round trip using xdoclet/hibernate/middlegen , u can go back and forth.  i 
hope somone really reads this and gives me a good answer.  it seemed it would 
be a bug not to include the meta back in .hbm files.thx.

2.1

Description:
ok, ive been using xdoclet/middlegen/hibernate for a good while now.. here is 
my procedure.

i only use middlegen in the earlier stage from a legacy database. it generates 
the .hbm WITH THE XDoclet tags, which i like...then i use java2hbm that 
generates the nice java files WITH THE Xdoclet tags.. NOW this is where round 
trip stopps and i havnt foudn a solution.   i change an Xdoclet tag, in the 
java class then run java2hbm(using xdoclet hibernate tool), and it DOES NOT 
include the xdoclet metadata tags in the .hbm files! When i run hbm2java again 
on the second generated hbm files , they create the java files WITHOUT the 
metadata tags ... is there a setting i can tell xdoclet to include the metadata 
tags when generating the hbm from java??

middlgen->hbm(with xdoclet tags)->hbmn2java->creates java(with xdoclet tags)

java2hbm(xdoclet plugin)->hbm(without xdoclet tags)-> :(

if possible please send me a response if im doing somthing wrong or this is a 
bug..thanks
