Xavier, Does getContent.do return anything? I ask because your error was shown to be JSP level, not servlet level. Are you returning 'null' from your action or do you invoke a forward to go to a JSP .... after .... you have closed your output stream with os.close() ? At that point I expect you to return null instead of an actionForward.

The getContent.do write a datahandler to the stream : response.setContentType(mimetype); OutputStream os = response.getOutputStream(); tosend.writeTo(os); os.flush(); os.close(); Remember my first mail, the problems occurs only after calling an other action like that : <html:form action="/updateContent.do" method="post" enctype="multipart/form-data"> <bean:message key="updatecontent" /> <html:file property="contentfile"/> <html:hidden property="root" value="${id}"/> <html:hidden property="type" value="METADATA"/> <html:submit/> </html:form> And the updatecontent action look like that (I remove all my business logic): request.setAttribute(Constants.Result,array); return mapping.findForward("successthumb"); So no getstream in this action.
