Paging :

public abstract class Paging {
    protected int offset = 0;
    protected int maxResults = 3;
    protected int collection = 0;
    protected BeerLover user;

    public BeerLover getUser() {
        return user;
    }

    public void setUser(BeerLover user) {
        this.user = user;
    }

    public void setCollection(int collection) {
        this.collection = collection;
    }

    protected boolean next;
    protected boolean prev;

    public boolean getNext() {
        return this.next;
    }

    public boolean getPrev() {
        return this.prev;
    }

    public int getMaxResults() {
        return this.maxResults;
    }

    public void setMaxResults(int maxResults) {
        this.maxResults = maxResults;
    }

    public int getOffset() {
        return this.offset;
    }

    public void setOffset(int offset) {
       this.offset = offset;
       if(this.offset + maxResults < collection) { next = true; }else{ next = false;}
       if(this.offset  >= maxResults) { prev = true;}else{ prev =false; }
   }

}

Class waarop ge paging wilt (ier eigen bierkes ):

public class BeersFacade extends Paging {

   public List<Beer> getEigen() {
      List<Beer> Eigen = new ArrayList();
      List<Beer> beers = user.getBeers();
      setCollection(user.getBeers().size());
      for(int i = offset ; i < offset + maxResults ; i++) {
        try {
            Beer b = beers.get(i);
            Eigen.add(b);
        }catch(Exception ex) {
            //Woops out of bounds ^^
        }
      }
      return Eigen;
   }
}


En de bean daarvan :

                <managed-bean-name>beers</managed-bean-name>
                <managed-bean-class>be.mct.model.BeersFacade</managed-bean-class>

                        <value>#{sessionScope.identity}</value>
                    </managed-property>
                    <managed-property>
