Transport Error 404 for rpc

[nwk313]

Hi guys, I am a newbie to SmartGWT and when I work out on the hibernate and it turns out to give me warning "Transport Error - HTTP code: 404 for URL: http://127.0.0.1:11874/orderDetailHibernateOperations.rpc". I am currently using SmartGWT EE 6.0p with GWT 2.7.0. Database is MySQL. Below is the error log.
