XPages: How to acces an application scope bean from a session scope bean - jsf

Question

I need a value from my application scope managed bean in my session scope managed bean. Not sure how to get this done. Saw a poste here: https://guedebyte.wordpress.com/2012/05/19/accessing-beans-from-java-code-in-xpages-learned-by-reading-the-sourcecode-of-the-extensionlibrary/ But I get a bunch of errors... I also found this: JSF 2.0 Accessing Application Scope bean from another Bean so IM thinking maybe I need to redefine my application bean??? Totally clueless...
How can I make that happen?
Here is the application scope bean's code:
public class AppConfig implements Serializable {
private static final long serialVersionUID = 2768250939591274442L;
public AppConfig() {
initDefaults();
initFromConfigDoc();
}

Answer 1

The VariableResolver goes through all implicit variables (e.g. session, database) as well as scoped variables (e.g. applicationScope.myVar). Your bean is also accessed from SSJS via the VariableResolver.
So you can use:
ExtLibUtil.resolveVariable(FacesContext.getCurrentInstance(), "myAppScopeBean");

Answer 2

This is not a direct answer to your question...
An alternative would be to set the value you want in applicationScope and then access it this way from your bean. To access the entire bean directly is a different answer.
You use this code get a handle to your applicationScope.
FacesContext facesContext = FacesContext.getCurrentInstance();
ExternalContext externalContext = facesContext.getExternalContext();
Map<String, Object> applicationScope = externalContext.getApplicationMap();
Then to use this you have code like this:
String agentLogDB = (String) applicationScope.get("LOGDB");
