hbm2java does not (yet) generated addX(T x) methods, it only generats set and getters - the methods needed for hibernate to work.
Please submit a JIRA request for this one if you wish - and any suggestion on what the addX(T x)/removeX(T x) should do (in respect to maintaining bidirectional relationsships) would be apprecied.

I used 'inverse=true' in my mapping file. But Workspace class
is not having 'addAsset(Asset)' method when I generate the classes using
hbm2java tool.
Does anyone have an idea on what could be the problem in generating the class files?
thanks

What you did was created mapping file first and from it you created
the Class files
I did exactly opposite I created the class files through poseidon
first and then created mapping file for it.
You can choose anyway you like.
just specify 'inverse=true'
your class would be looking like this
public class Workspace{
private list asset; file://getter and setters would alway be for
this variable
public void addAsset(Asset _asset){
if(asset==null)asset=new ArrayList();
asset.add(_asset);
_asset.setWorkspace(this);
}
}
public class Asset{
private Workspace workspace;//getter and setters would always be
for this variable
}
This code should do the job for you
But relationship has to go two ways. When you say
session.save(workspace) it should save every association.
