ManagedBean isn't instantiated?

I'm starting my first steps in JSF.

I've already read this link

http://docs.oracle.com/javaee/6/tutorial/doc/bnawq.html#bnaww

in regards to map initialization.

The problem is, I want to populate my map with values residing in a file.

How can I do that?

I've tried not using faces-config.xml and calling a support method in the bean's constructor, but my select list box isn't populated.

My bean class:

@ManagedBean
    public class ADGroupListBean {

private static final String WITH_ACCESS = "D:\\workspace\\AccessControl\\permissions.txt";
	private static final String WITHOUT_ACCESS = "D:\\workspace\\AccessControl\\noPermissions.txt";
	private Map<String,String> withAccess, withoutAccess;

private LDAPQueries queries;

public ADGroupListBean(){

withAccess = new LinkedHashMap<String, String>();
		withoutAccess = new LinkedHashMap<String, String>();

queries = new LDAPQueries();

initList(WITH_ACCESS, withAccess);
		initList(WITHOUT_ACCESS, withoutAccess);

}

private void initList(String filename, Map<String,String> list) {

File f = new File(filename);

if ( !f.exists() && f.getAbsolutePath().equals(WITHOUT_ACCESS) )
		{
			queries.queryAllGroups(WITHOUT_ACCESS);
		}

try 
		{	
			
			Scanner sc = new Scanner(f);

while (sc.hasNext())
			{
				String group = sc.nextLine();
				list.put(group, group);
			}

}catch (IOException e) {

e.printStackTrace();
		}

}

//	public void populateList() {
	//		
	//		
	//	}
	
	public Map<String,String> getWithAccess() {

return withAccess;
	}

public Map<String,String> getWithoutAccess() {

return withoutAccess;
	}

public void setWithoutAccess(Map<String,String> withoutAccess) {

this.withoutAccess = withoutAccess;
	}

public void setwithAccess(Map<String,String> withAccess) {

this.withAccess = withAccess;
	}
	
	public void test() {
		
		System.out.println("workssssssssssssssssss");
	}
    }

As for my JSF file, it is like this:

I've tested the bean's functions in a test application, and everything works fine.

So my guess is the bean isn't instantiated?

the definition of your class does not specify a managed bean name...
so the default name would be "aDGroupListBean"
since bean names are case sensitive, update your jsf file using
<f:selectItems value="#{aDGroupListBean.withoutAccess}" />
