Ok, found the answer.

For anyone interested, when you are using remote clients add hibernate3.jar to your list of library's.

I'm trying to setup a bidirectional onetomany with ejb3.

If I just have the manytoone side everything works fine, as below

@ManyToOne
@JoinColumn(name="MODULEID_FK", nullable=false)
public Module getModule() {
return module;
}
public void setModule(Module module) {
this.module=module;
}


However if I add the onetomany side in as follows

@OneToMany(mappedBy="module")
public List<Bale> getBales() {
return bales;
}
public void setBales(List<Bale> bales) {
this.bales = bales;
}


I get the following error from the client. Any help would be great.

Thanks,
Mark.
