Retrieving Managed Beans Programmatically

Incase of ADF applications, sometimes we need to access one managed bean properties from another managed bean. Following code provides details on how to access managed beans programmatically specified in different scopes.

import javax.faces.context.ExternalContext;
import javax.faces.context.FacesContext;

ExternalContext exctx = FacesContext.getCurrentInstance().getExternalContext();

AppBean appBean = (AppBean) exctx.getApplicationMap().get("appBeanName");
SessionBean sessionBean = (SessionBean) exctx.getSessionMap().get("sessionBeanName");
RequestBean sessionBean = (RequestBean) exctx.getRequestMap().get("requestBeanName");

AdfFacesContext adfctx = AdfFacesContext.getCurrentInstance();

ViewBean viewBean = (ViewBean)adfctx.getViewScope().get("viewBeanName");
PageFlowBean pageFlowBean = (PageFlowBean)adfctx.getPageFlowScope().get("pageFlowBeanName");
