How do I get and set an object in session scope in JSF? -

i need persist 1 object in session scope of jsf application. define session variable, , how , set either view file or backing bean?

several ways:

• use externalcontext#getsessionmap()

  externalcontext externalcontext = facescontext.getcurrentinstance().getexternalcontext(); map<string, object> sessionmap = externalcontext.getsessionmap(); sessionmap.put("somekey", yourvariable); 

  and later:

  someobject yourvariable = (someobject) sessionmap.get("somekey"); 

• or, make property of session scoped bean inject in request scoped bean.

  sessionbean.setsomevariable(yourvariable); 

  and later:

  someobject yourvariable = sessionbean.getsomevariable(); 

  injection of beans in each other can happen faces-config.xml described here or if you're on jsf 2.0, @managedproperty

  @managedbean @requestscoped public class requestbean {     @managedproperty("#{sessionbean}")     private sessionbean sessionbean;     // ... } 

  with

  @managedbean @sessionscoped public class sessionbean {     private someobject somevariable;     // ... }
