                  update="messages" sizeLimit="100000" fileLimit="3" 
                  allowTypes="/(\.|\/)(gif|jpe?g|png)$/" />

    <p:growl id="messages" showDetail="true" />
</h:form>

@ManagedBean

public class FileUpload{

    public void handleFileUpload(FileUploadEvent event) {
        FacesMessage message = new FacesMessage("Succesful", event.getFile().getFileName() + " is uploaded.");
        FacesContext.getCurrentInstance().addMessage(null, message);
    }
}
