Some help please,
I have an excel file for download, I need to get the md5 of the file, an xhtml written for the excel is like this:
exportarExcel.xhtml
<e:workbook xmlns:ui="http://java.sun.com/jsf/facelets" xmlns:e="http://jboss.com/products/seam/excel" xmlns:f="http://java.sun.com/jsf/core" xmlns:s="http://jboss.com/products/seam/taglib" xmlns:c="http://java.sun.com/jstl/core"> <f:loadBundle basename="messages" var="m"/> <e:worksheet id="listado" var="persona" value="#{busquedaResultado}" > <e:column> <f:facet name="header"> <e:cell value="#{m['APELLIDO_PATERNO']}"/> </f:facet> <e:cell value="#{persona.apellidoPaterno}"/> </e:column> </e:worksheet>
This xhtml (excel workbook) is called from an ejb:
public String exportarExcel(){ //populate the with data #{busquedaResultado} (e:workbook) value, no porblem //then call the xhtml, and download box apers and downloads just fine return "/exportarExcel.xhtml"; }
What I really need is to get and md5 from this download file, get/capture file, pass it to and md5 (that i allready have and then make the download) md5 method will recive as parameter File or ByteArrayOutputStream, well the input can be converted, the problem, how can I get the file before the download???
Any help really apreatiated. Thanks for your time.
