Hi Norman, 1) As you see in your log -> java.lang.NoClassDefFoundError: sung/app/kylintv/product/Product , one of your Classes or package can't be found by the server runtime.
Are you sure that your *.war is well generated ? Open your *.war with a ZIP utility tool and check if there is a 'Product.class' and 'sung.app.kylintv.product' package. Sometimes Eclipse War exportation tool don't include package or classes with compilation warnings. 2) Of course GWT applications work with EJB...So in my opinion EJBs are not the problem. You'll tell me later. I hope it helps. Karim Duran. 2011/9/15 Norman Klingspor <[email protected]> > Hello, > > I'm trying to establish a shop-system through gwt.
