ValueBinding throw a servlet

[omidh <om...@gmx.de>]

Hi all,

I wrote a servlet for File Download. I am developing a portlet and the
download is from a DB.
So when I am in the servlet doGet() and try to receive a bean from the
FacesContext
I get a NullPointerException, here the code:

FacesContext fctx = FacesContext.getCurrentInstance();
		//DetailsBean bean =
(DetailsBean)fctx.getApplication().getVariableResolver().resolveVariable(fctx,
"detailsBean");
		ValueBinding bind = FacesContext.getCurrentInstance().getApplication().
								createValueBinding("#{detailsBean}");
		DetailsBean bean = (DetailsBean)bind.getValue(fctx); 

the faces-config Entry:

<managed-bean>
		<managed-bean-name>facadeService</managed-bean-name>
	
<managed-bean-class>main.org.jboss.portlet.milestone.jsf.facade.FacadeService</managed-bean-class>
		<managed-bean-scope>application</managed-bean-scope>
		<managed-property>
			<property-name>mileStoneService</property-name>
		
<property-class>main.org.jboss.portlet.milestone.spring.service.MileStoneService</property-class>
			<value>#{mileStoneService}</value>
		</managed-property>
		<managed-property>
			<property-name>mileStoneSearchService</property-name>
		
<property-class>main.org.jboss.portlet.milestone.spring.service.MileStoneSearchService</property-class>
			<value>#{mileStoneSearchService}</value>
		</managed-property>
	</managed-bean>

any ideas?

thanks in advance,
Omid

Hi again,
I solved the problem.
for the intressted reader ;) :
protected FacesContext getFacesContext(HttpServletRequest request,
			HttpServletResponse response) {
		FacesContext facesContext = FacesContext.getCurrentInstance();
		if (facesContext == null) {

			FacesContextFactory contextFactory = (FacesContextFactory) FactoryFinder
					.getFactory(FactoryFinder.FACES_CONTEXT_FACTORY);
			LifecycleFactory lifecycleFactory = (LifecycleFactory) FactoryFinder
					.getFactory(FactoryFinder.LIFECYCLE_FACTORY);
			Lifecycle lifecycle = lifecycleFactory
					.getLifecycle(LifecycleFactory.DEFAULT_LIFECYCLE);

			facesContext = contextFactory.getFacesContext(request.getSession()
					.getServletContext(), request, response, lifecycle);
		}
		return facesContext;
	}
