Upload zip file in JSF 2.2 with ajax -

-

in application can upload zip file. i'd incorporate ajax. how can ajax work zip files?

right now, code looks this:

    <h:form id="form" enctype="multipart/form-data" prependid="false"         pt:class="form-inline" pt:role="form"         rendered="#{consolecontroller.getadmin() != null}">         <div class="form-group">             <label class="sr-only" for="file">file:</label>             <h:inputfile id="file" value="#{uploadcontroller.file}" />         </div>         <h:commandbutton id="button" value="upload"             action="#{uploadcontroller.upload}" class="btn btn-default">             <f:ajax execute="file" render="@all" />         </h:commandbutton>     </h:form>

i following error in form of modal window in chrome:

malformedxml: toplevel node must 1 of: changes, redirect, error,...

i having same problem every time tried render(using ajax) forms of type enctype="multipart/form-data". instead of using render="@all", try render manually forms want except form "form". ex: render=":form2 :form3 : form4"
