Re: How I can read managed property value from faces-config file in class constructor?

[Yogesh Chaudhari]

Hi Dennis, Laurie thanks for the prompt reply.

I found following code on jsffaq.com, I will try it work for me.

FacesContext fc = FacesContext.getCurrentInstance();
String userName =
(String)fc.getApplication().createValueBinding("#{Person.userName}").getValue(fc);


 <managed-bean>
        <managed-bean-name>Person</managed-bean-name>
        <managed-bean-class>demo.PersonBean</managed-bean-class>
        <managed-bean-scope>request</managed-bean-scope>
        <managed-property>
                <property-name>userName</property-name>
                <property-class>java.lang.String</property-class>
                <value/>
        </managed-property>
 <managed-bean>


Thanks again, Yogesh
