Forget about the RenderResource! Just tried it out but JBoss Portal 2.7
responded with an not yet implemented Exception!
What JSR 286 compliant container is JBoss Portal 2.7?? For my opinion it is not
compliant to the JSR 286 Specification in any way!!!
Here's the code for anyone runnning a JSF Application via the Portlet Bridge:
public String getRenderResourceUrl() {
Object responseObject =
FacesContext.getCurrentInstance().getExternalContext().getResponse();
if (responseObject instanceof RenderResponse) {
RenderResponse response =
(RenderResponse)responseObject;
return response.createResourceURL().toString();
}
return "";
}
to anyone else who is a native Portlet you can use:
<html xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'
xmlns:portlet="http://java.sun.com/xml/ns/portlet/portlet-app_2_0.xsd";
xsi:schemaLocation="http://java.sun.com/xml/ns/portlet/portlet-app_2_0.xsd
http://java.sun.com/xml/ns/portlet/portlet-app_2_0.xsd";>
<portlet:resourceURL var="signedPdf"/>

If you are running in a JSR 168 compliant Portlet Container you can try to get
access to the HttpServletRequest where you can set the ContentType:
public HttpServletRequest getHttpServletRequest(PortletRequest request)
{
PortletInvocation portletInvocation = (PortletInvocation)
request.getAttribute(ContextDispatcherInterceptor.REQ_ATT_COMPONENT_INVOCATION);
return portletInvocation.getDispatchedRequest();
}
The problem with this approach is that JBoss Portal overrides the ContentType
after you set it.
For my opinion the only solution is to forward to a Servlet to handel PDF
downloads! The worst solution as you do not have any access to the Portlet
attributes any more. But JBoss does not offer any other solution.
Looks to me that they ignore the fact of using JBoss Portal in real world
systems. Watch out for Liferay they give you solutions for down- and uploading
files.
