Hi I've tried two different techniques for sending a file to a browser(making the user download a file). I've tried an example from myfaces wikipage

I have also tried using a component named fileDownload from PrimeFaces. Both give the same result:

I get a response from the server, the response contains text that should be in the file. The header is a follows:

X
To me this looks correct but for some reason I don't get to download the file, I just get this response in firebug.

Does anyone have any idea?, could it be a serversetting problem? I using glassfish 3

Thanks / Stefan

Try using "application/force-download" instead of "text/plain".

It didn't work. I think the problem lies in JSF and facelets. I use a facelet and a template.

Template

Facelet

<f:view xmlns="http://www.w3.org/1999/xhtml"
	xmlns:f="http://java.sun.com/jsf/core"
	xmlns:h="http://java.sun.com/jsf/html"
	xmlns:ui="http://java.sun.com/jsf/facelets"
	xmlns:p="http://primefaces.prime.com.tr/ui"
	xmlns:c="http://java.sun.com/jsp/jstl/core" contentType="text/html"
	xmlns:em="http://java.sun.com/jsf/composite/emcomp/"
	xmlns:fn="http://java.sun.com/jsp/jstl/functions">

<ui:composition template="/templates/masterLayout.xhtml">
		<ui:define name="content">

<h:form id="form" >
			
				<p:panel header="Velg Election event" style="margin-bottom:10px;" rendered="#{ChooseExportController.selectEvent}">
					<h:selectOneMenu value="#{ChooseExportController.eventPk}" 
						onchange="this.form.submit();" 
						valueChangeListener="#{ChooseExportController.eventListener}">
						<f:selectItem itemLabel="" itemValue="0"/>
						<f:selectItems
							value="#{ChooseExportController.electionEventList}" var="n"
							itemLabel="#{n.name}" itemValue="#{n.pk}" />
					</h:selectOneMenu>
				</p:panel>

<p:messages errorClass="errors" layout="table" showDetail="true"
					globalOnly="true" />
 				<p:dataTable id="datatable" value="#{ChooseExportController.operatorRoleList}" rendered="#{ChooseExportController.selectRole}"
					var="operatorRole" border="1" selectionMode="single"
					selection="#{ChooseExportController.operatorRole}" paginator="true" rows="10">
					<p:column sortBy="#{operatorRole.role.name}">
						<f:facet name="header">
							<h:outputText value="Name" />
						</f:facet>
						<h:outputText value="#{operatorRole.role.name}" />
					</p:column>
					<p:column sortBy="#{operatorRole.mvArea.areaLevelString}">
						<f:facet name="header">
							<h:outputText value="OmrÃ¥desnivÃ¥" />
						</f:facet>
						<h:outputText value="#{operatorRole.mvArea.areaLevelString}" />
					</p:column>
					<p:column sortBy="#{operatorRole.mvArea}">
						<f:facet name="header">
							<h:outputText value="OmrÃ¥deskontekst" />
						</f:facet>
						<h:outputText value="#{operatorRole.mvArea}" />
					</p:column>
					<p:column sortBy="#{operatorRole.mvElection.electionLevelString}">
						<f:facet name="header">
							<h:outputText value="ValgnivÃ¥" />
						</f:facet>
						<h:outputText value="#{operatorRole.mvElection.electionLevelString}" />
					</p:column>
					<p:column sortBy="#{operatorRole.mvElection}">
						<f:facet name="header">
							<h:outputText value="Valgkontekst" />
						</f:facet>
						<h:outputText value="#{operatorRole.mvElection}" />
					</p:column>
				</p:dataTable>
				
			 	<br />
			 	<p:commandButton value="Velg rolle" id="selectRole" action="#{ChooseExportController.download}"/>

But if I rewrite the facelet like this, the download works, and it works with the mimetype text/plain

<p:dataTable id="datatable" value="#{ChooseExportController.operatorRoleList}" rendered="#{ChooseExportController.selectRole}"
					var="operatorRole" border="1" selectionMode="single"
					selection="#{ChooseExportController.operatorRole}" paginator="true" rows="10">
					<p:column sortBy="#{operatorRole.role.name}">
						<f:facet name="header">
							<h:outputText value="Name" />
						</f:facet>
						<h:outputText value="#{operatorRole.role.name}" />
					</p:column>
					<p:column sortBy="#{operatorRole.mvArea.areaLevelString}">
						<f:facet name="header">
							<h:outputText value="OmrÃ¥desnivÃ¥" />
						</f:facet>
						<h:outputText value="#{operatorRole.mvArea.areaLevelString}" />
					</p:column>
					<p:column sortBy="#{operatorRole.mvArea}">
						<f:facet name="header">
							<h:outputText value="OmrÃ¥deskontekst" />
						</f:facet>
						<h:outputText value="#{operatorRole.mvArea}" />
					</p:column>
					<p:column sortBy="#{operatorRole.mvElection.electionLevelString}">
						<f:facet name="header">
							<h:outputText value="ValgnivÃ¥" />
						</f:facet>
						<h:outputText value="#{operatorRole.mvElection.electionLevelString}" />
					</p:column>
					<p:column sortBy="#{operatorRole.mvElection}">
						<f:facet name="header">
							<h:outputText value="Valgkontekst" />
						</f:facet>
						<h:outputText value="#{operatorRole.mvElection}" />
					</p:column>
				</p:dataTable>
				
			 	<br />
			 	<p:commandButton value="Velg rolle" id="selectRole" action="#{ChooseExportController.download}"/>

Any ideas?

Try this.
response.setContentType("application/vnd.ms-word");

Because for the plain text some time browser displays content directly in the screen instead of giving download option.

It figured out the problem.
I was using the primefaces commad button that does a partial ajax submit. Changed to jsf commandbutton and everything works
