DWR:Missing method or missing parameter converters

<create creator="new" javascript="CC">
            <param name="class" value="dwr.CC" />
        </create>

        <convert converter="bean" match="dwr.User" />

 配置好以后，放入参数，我这里是dsdsd，就哦了

function OnSave() {
var dsdsd = {};
dsdsd.id = regForm.id.value;
dsdsd.password = regForm.password.value;
dsdsd.name = regForm.name.value;
dsdsd.email = regForm.email.value;
CC.save(dsdsd, saveFun);
}
