Feature taxintegration ds2

There is no need to create these local variables, and no need for a separate populate function in the request bean.  You can just do:

taxRatesRequestBean.setOrderID( arguments.order.getOrderID() );
taxRatesRequestBean.setOrderID( arguments.order.getOrderID() );
taxRatesRequestBean.setAccountID( arguments.order.getAccount().getAccountID() );
