      Hi,

      We are facing following issue while creating an excel file from BPM.

      There is a JSP file which invokes the method of BPM, which inturn creates a excel file.

      In JSP we are calling the method in the following way:

      function exportSelectedItemsToExcel(){
           var url="<f:invokeUrl var='reportingView' methodName='exportToExcel'/>";
           url = url + "&bpmRespContentType=application/vnd.ms-excel";
           var windowHandle = window.open(url,'windowName','width=800, height=600, resizable=1, menubar=1');
      }

      POI jars are used to create the excel.
      Also we recently did the migration and applied a patchset of 10.3.3 on 10.3.2. In the previous verison(10.3.2) it was working perfectly fine. When i am trying to test it on localstudio, it is generating the excel file properly.

      Have any one faced any such issues while migration or any other time?
