WEB GUI Research Based On Metamodel

In　the　current　WEB　application　system,　user　interfaces　specify　conversation　channel　between　the　applications　and　their　users,　which　are　important　sections　of　the　WEB　system.　They　effect　the　whole　application's　effectiveness　and　usability。It　is　very　considerable　to　develop　the　work　load　of　user's　interface　and　degree　of　difficulty　at　present,　the　layman　is　very　difficult　to　develop　by　oneself　,　usually　the　programmer　adopts　the　specific　programming　language　such　as　ASP,JSP　etc.　User　interfaces　designed　in　this　way　need　constant　communication　between　the　programmers　and　users　as　it　need　to　be　modified,　and　if　an　other　programming　language　were　adopt,　the　work　done　in　the　past　can　not　be　re-utilized　in　normally,　at　the　same　time　the　development　method　neglects　the　individual　character　of　user's　interface　.　So,　adopt　the　interface　of　user　of　the　graphic　presentation　simple,　ocular　modeling　building　and　income　,　and　face　the　layman's　user's　interface　modeling　system　and　have　very　important　meanings.　This　text　analyse　existing　problem　of　current　dynamic　WEB　application　system,　is　it　adopt　a　way　of　meta-model　describe　to　user　interface　to　put　forward,　draw　at　present　using　extensive　WEBForm　technology　and　J2EE　hitting　ECHO　experience　of　software　of　the　system　of　.　NET,　adopt　interfaces　and　design　MVC　mode　that　is　generally　used　,　has　studied　a　dynamic　WEB　system　based　on　finding　and　income　of　J2EE,　and　come　into　operation　in　the　actual　project,　the　result　is　good.
