Как перенаправить другую страницу zk после успешной проверки всех полей с помощью java? Здесь я создал страницу .zul для создания формы, а затем проверил все поля в классе Java. Теперь я должен перенаправить страницу после завершения проверок.

index.zul

 <zk>
<style>
        .z-window-embedded-tl,.z-window-embedded-tr,.z-window-embedded-hl,.z-window-embedded-hr,
        .z-window-embedded-hm 
        { 
            background-image:none;
            background-color:#94D3D3; 
        } 
        .z-window-embedded-cnt 
        { 
            border:1px
            solid #7BADAD; 
        }
</style>
<script defer="true">
      var oldMessage = jq.alert;
      jq.alert = function(msg, opts) {
      if(!msg.indexOf('the request was rejected because its size') || !msg.indexOf('The request was rejected because the file size'))
      zk.Widget.$('$info').setValue("Oh! Upload fail because of Size.");
     else
      oldMessage(msg, opts);}

пожалуйста, предложите, как это сделать. я новичок в ZK

Вы можете использовать Executions.sendRedirect(String url) или Executions.forward(String)
