How to get managedbean property from another bean in JSF

Question

I searched similar questions but I\'m a bit confused. I have a login page, so LoginBean also which is;

@ManagedBean(name = \"loginBean\")
@SessionScoped
publ

The @ManagedProperty declares the location where JSF should set the property, not where JSF should "export" the property. You need to just inject the LoginBean as property of OrderBean.

public class OrderBean {

    @ManagedProperty(value="#{loginBean}")
    private LoginBean loginBean; // +setter

    // ...
}

This way you can access it in the OrderBean by just

loginBean.getIdentityNr();

Alternatively, if you make your OrderBean request or view scoped, then you can also set only the identityNr property.

public class OrderBean {

    @ManagedProperty(value="#{loginBean.identityNr}")
    private String identityNr; // +setter

    // ...
}

Unrelated to the concrete problem: initializing String properties with an empty string is a poor practice.
