swf facelets externalRedirect

[jokrasa]

Hey to all!

I'm trying to get an externalRedirect ro some way or redirecting to a pdf page residing
at WEB-INF/reports/report2.pdf for example...


my view state is in:

<?xml version="1.0" encoding="UTF-8"?>
<flow xmlns="http://www.springframework.org/schema/webflow"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://www.springframework.org/schema/webflow http://www.springframework.org/schema/webflow/spring-webflow-2.0.xsd">

    <secured attributes="ROLE_USER" />

    <persistence-context/>
        <var name="hotelReport" class="org.springframework.webflow.samples.jasper.HotelReport" />
        <var name="reportController" class="org.springframework.webflow.samples.jasper.ReportController" />
        <input name="searchCriteria" required="true" />

        <on-start>
            <evaluate expression="bookingService.addMsg('now in subflow...')" />
        </on-start>
        <view-state id="hotelReport.view" view="externalRedirect:http://localhost:8080/swf-booking-faces/spring/reports/report.pdf" popup="true">
            <on-entry>
                <!-- <evaluate expression="reportController.handleSimpleReport(bookingService.findHotels(searchCriteria,externalContext.locale))" result="flashScope.modelAndView" /> -->
               <evaluate expression="bookingService.makeHotelReport(bookingService.findReportHotels(searchCriteria,externalContext.locale))" />
                <evaluate expression="bookingService.addMsg('entered view-state displayPdfState')" />
            </on-entry>
            <transition to="report.end"/>
        </view-state>

        <end-state id="report.end" />

</flow>

I've tried everything to get my view to get simply handled/resolved to this path...

Problem is that I'm using facelets and my comfiguration just maps/resolves to:

http://localhost:8080/swf-booking-fa...s/report.xhtml as per the UrlBasedViewResolver

	</bean>

			
</beans>

what changes could i make to force the redirect to bypass the UrlBasedViewResolver??

I've tried many things even an external servlet but nothing works?

Any help appreciated,

cheers!

I guess I should elaborate on the situation.

I'm taking the swf-booking-faces sample bundled in the SWF distribution ver2.0.5 (a recent distr)
and getting the reviewHotels.xhtml to have a sf:commandLink that will print the Hotels searchResult (as a popup) using
jasperreports.

OK so I can produce the report.pdf to a folder on the classpath, no problem. But how could you open the view using webflow?
(I've tried many classpath locations, settled on

C:\NetBeansProjects\swf-booking-faces_sept18\src\main\webapp\reports\report.pdf

since that will open with

http://localhost:8084/swf-booking-faces/reports/report2.pdf

)

The only way I can open it is with:

<view-state id="report2.view" view="externalRedirect:/reports/report2.pdf">

but then I get the first cached version produced when the server started and the <view popup=true doesn't work
with externalRedirects.

It seems the only way to have the report work is with

<a href="simpleReport.pdf" target="_blank">Printable list</a>

that will only compile a hardcoded data ( via the JasperReportsPdfView class )with no interaction with current view (ie: you couldn't send the search criteria to the query).

There must be a way to produce the report in a flow that will have access to flow vars. If you separate the report to a controller with req/resp it won't interact with the flow and xhtml components,... leaves you cold!

I have managed to popup the report but it creates parse errors since it's a pdf file...

What to do?

Has anyone been able to open pdf jasperreports using the swf-booking-faces sample yet?

Regards,

John

P.S. tried everything, separate servlet etc, gets swallowed up/busted by the framework.
