Subject: Re: [Hibernate] relationship not
getting saved
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.
