Thanks Kito for the suggestion. I would like to do something like this ...
public String createManufacturer() {
          
        try{
                manufManager.createManufacturer(namsManufacturer);
                FacesUtils.addInfoMessage("save", "Manufacturer",
namsManufacturer.getName());                                                    
        

        }catch(DuplicateManufacturerIdException ex) {
          
                System.out.println(" catching DuplicateManufacturerIdException 
In Backing
Bean");
        
FacesContext.getCurrentInstance().getExternalContext().getRequestMap().put("errors",
ex.getMessages()); 
                return "error";
                
    }
        catch(Exception e) {
        logger.warn(e.getMessage());
    }
    
        return "success";

  }
Let say if i have "error" defined in navigation-rule to print errors on
different or same page. How should i iterate thru the meesage list  and
print them on browser. I know its available in RequestMap.
A code snippet will be highly appreciated

Regards
Bansi
