returning a class from a Session EJB

[viper2003]

I have an session ejb(MyEJB) that calls a class(skuObj.class) with a bunch of getters and setters, I retrieve a record from the database and set the row to the class like this skuObj.setSKU(the value from db).. and so on.
after that I return the class object.So my ejb Method looks like this;

NOT ALL THE CODE IS HERE IS JUST TO GIVE AN IDEA OF WHAT I AM TRYING TO DO.

public skuObj getSku(String _sku_cd) throws EJBException {
skuObj sku = new skuObj();
sql = "select * from sku where sku_cd = '" + _sku_cd + "'";
sku.setSku_cd(rs.getString("sku_cd"));
sku.setSku_desc(rs.getString("sku_desc"));
sku.setSku_class(rs.getString("sku_class"));

return sku;
}

The EJB resides in a Jboss server, so If I call the EJB from the local server, I have no problem. The problem is tha I need to call the EJB from a remote server running tomcat, I get a java.io.Exception error. I know I need to serialize the skuObj.class object in order to pass it to the remote server, and I have been looking for an example on this, but can't find any.
Is this even possible? I am quite sure it is possible, but I can not find an kind of reference to this and that is making me think otherwise.

Thanks for any help provided!
