Java EE (Java Enterprise Edition) General Discussion

Hi All,
I am working on a servlet that allows the user to post information, but it seems that I am having some trouble getting the session. It consistently dies when trying to get the session. Any help you can give me will be greatly appreciated!!! Thanks!!!

I am getting this error:

PWC3999: Cannot create a session after the response has been committed
java.lang.IllegalStateException: PWC3999: Cannot create a session after the response has been committed

Here is the code I am working on:

public class ControllerFactory {
    private Controller Controller;

    
    public ControllerFactory(WebServiceContext wsContext) throws ServletException
    {
        MessageContext mc = wsContext.getMessageContext();
        ServletRequest request=(javax.servlet.http.HttpServletRequest)
            mc.get(MessageContext.SERVLET_REQUEST);
        ServletResponse response=(javax.servlet.http.HttpServletResponse)
            mc.get(MessageContext.SERVLET_RESPONSE);
        FacesContext facesContext=this.getFacesContext(request, response);
        ELContext elContext=facesContext.getELContext();
        
        
        jamController = (JAMController) elContext.getELResolver()
                .getValue(elContext, null, "JamList");

    }
    

    private static abstract class InnerFacesContext extends FacesContext {

        protected static void setFacesContextAsCurrentInstance(FacesContext facesContext) {
            FacesContext.setCurrentInstance(facesContext);
        }
    }

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

        //ServletContext servletContext = ((HttpServletRequest) request).getSession().getServletContext();

        ServletContext servletContext = mySession.getServletContext();
        
        facesContext = contextFactory.getFacesContext(servletContext, request, response, lifecycle);

        // Set using our inner class
        InnerFacesContext.setFacesContextAsCurrentInstance(facesContext);

        // set a new viewRoot, otherwise context.getViewRoot returns null
        UIViewRoot view = facesContext.getApplication().getViewHandler().createView(facesContext, "");
        facesContext.setViewRoot(view);
        facesContext.responseComplete() ;
        return facesContext;
    }
    
        public Controller JamController() {
