I use xjc or IDEA to trans xml schema to java class. But failed. i'm not sure whether my XSDs correct(its has no targetNameSpace). so the xjc can't convert them to different package. if i customize the binding package, xjc cmd failed with "can't bing " " namespace more than once. below is response_trans_conf_list.xsd file, is't same to yours? if you trans your XSDs to java success , can you show me the package structures?
