Working with different scopes in ADF

This blog we will see how to use the different scopes like Application Scope, PageFlow Scope, Session Scope, Request Scope in ADF.

Request Scope:

FacesContext fcx =FacesContext.getCurrentInstance();
 
// Set Into Request Scope value
ExternalContext exCntx =fcx.getExternalContext();
exCntx.getRequestMap().put("key","value");
 
//get Request Scope value
ExternalContext exCntx =fcx.getExternalContext();
exCntx .getRequestMap ().get("key");

Application Scope:

FacesContext fcx =FacesContext.getCurrentInstance();
 
// Set Into Application Scope value
ExternalContext exCntx =fcx.getExternalContext();
exCntx.getApplicationMap().put("key","value");
 
//get Application Scope value
ExternalContext exCntx =fcx.getExternalContext();
exCntx . getApplicationMap ().get("key");

Session Scope:

FacesContext fcx =FacesContext.getCurrentInstance();

// Set Session Scope value
ExternalContext exCntx =fcx.getExternalContext();
exCntx.getSessionMap ().put("key","value");

//get Session Scope value
ExternalContext exCntx =fcx.getExternalContext();
exCntx . getSessionMap ().get("key");

PageFlow Scope:

// Set Into PageFlow Scope value
RequestContext.getCurrentInstance().getPageFlowScope().put("key","value);
 
// Get PageFlow Scope value
RequestContext.getCurrentInstance().getPageFlowScope().get(name);
