I have this code..

package com.uydomotic.log; import java.io.IOException; import javax.naming.Context; import javax.naming.InitialContext; import org.apache.log4j.Level; import org.apache.log4j.Logger; import org.apache.log4j.PatternLayout; import org.apache.log4j.Priority; import org.apache.log4j.RollingFileAppender; import com.uydomotic.excepciones.BusinessException; import com.uydomotic.parametros.Parametros; import com.uydomotic.servicios.IParametroEJB; /*** * * Se puede hacer que la lectura de opciones sea desde un archivo de esta forma obtenemos la funcionalidad de * carga dinamica que nos provee el log4jproperties. * */ public class AppLogger { private static AppLogger instancia=null; private Logger log = null; public AppLogger() throws IOException, BusinessException{ String logfile; //IParametroEJB paramEJB = lookup(IParametroEJB.class); //logfile = paramEJB.getValorParametro(Parametros.UYDOMOTIC_LOGGER_PATH); //if (logfile == null){ // throw new BusinessException("error_parametroNoSeteado", new Object[]{Parametros.UYDOMOTIC_LOGGER_PATH} , null); //} log = Logger.getLogger("uyDomotic"); PatternLayout defaultLayout = new PatternLayout("%p %c,line %L,%d{dd.MM.yyyy/HH:mm:ss},%m%n"); RollingFileAppender rollingFileAppender = new RollingFileAppender(); //new File("logs/"+path).createNewFile(); rollingFileAppender.setFile("logs/log.log", true, false, 0); rollingFileAppender.setAppend(false); rollingFileAppender.setMaxFileSize("10MB"); rollingFileAppender.setMaxBackupIndex(15); rollingFileAppender.setLayout(defaultLayout); //log.removeAllAppenders(); log.setLevel(Level.INFO); log.addAppender(rollingFileAppender); log.setAdditivity(false); } public static AppLogger getInstance() throws IOException, BusinessException{ if (instancia==null){ instancia=new AppLogger(); } return instancia; } public void miError(String msj){ log.error(msj); } public void miInfo(String msj){ log.info(msj); } @SuppressWarnings({ "unchecked" }) protected static <T>T lookup(Class<T> remoteInterface) { try { Context jndiContext = new InitialContext(); String beanName = remoteInterface.getSimpleName().substring(1); // Remuevo la 'I' de la interfaz T bean = (T) jndiContext.lookup("UyDomotic/" + beanName + "/local"); return bean; } catch (Exception e){ throw new RuntimeException(e); } } }

And when i call the logging functions like this..


AppLogger.getInstance().miInfo("hola"); AppLogger.getInstance().miError("chau");

The JBoss Server logs the messages on the console but the log.log file is empty.

I want to log the messages in that file. Any ideas?

Vijitha, thanks for the response.

A few days ago i realized that I was somehow wrong, since the query did find results. That is to say, it finds a result in the DB with the name pass as parameter and the query returns a property of that result that it turns out to be null.
Therefore, it finds a result that is null, that is different to not finding a result at all.

Anyway, thanks for your time!

Cheers!

Hi, im having trouble with the code listed below.

try{ return (String)entityManager.createNamedQuery("Parametro.getValorParametroByNombre") .setParameter("nombre",nombre) .getSingleResult(); }catch(NoResultException e){ throw new RuntimeException(new BusinessException("error_noExistePrametro", new Object[]{nombre}, e)); }

When i the system execute the code it returns null insted of throwing an exception.

I donno why.

There are 3 great JSF2 books.

1. Core Java Server Faces 3rd Edition
2. Java Server Faces 2. The complete Reference.
3. JSF 2 Cookbook.

I recommend the first one since is the easiest to understand.

Cheers!

Banging my head after few hours, i figured out that I was calling limpiarFormulario() before it get initiated/born. So I was getting a null pointer in utilEJB class. The idea seems to be that I need to use the @PostConstruct init method to call the limpiarFormulario() since the EJB are already injected. The problem is that the @PostConstruct is never called.

Can anybody explain me why???

@ManagedBean(name="categoriaBean") @SessionScoped public class CategoriaBean extends ABMBean { @EJB private ICategoriaEJB categoriaEJB; @EJB private IUtilEJB utilEJB; private Categoria categoria; private List<Categoria> categorias; @PostConstruct public void init(){ System.out.println("se ejecuto el postConstruct"); } public CategoriaBean() { super("categoria"); categoria = new Categoria(); System.out.println("pero esto si se ejecuto"); //limpiarFormulario(); esto va despues de que arreglemos lo del @PostConstruct } public Categoria getCategoria() { return categoria; } public void setCategoria(Categoria categoria) { this.categoria = categoria; } public List<Categoria> getCategorias(){ return (List<Categoria>) utilEJB.getEntidades(Categoria.class); } public void setCategorias(List<Categoria> categorias) { this.categorias = categorias; } @Override public void limpiarFormulario() { categoria = new Categoria(); categorias = (List<Categoria>) utilEJB.getEntidades(Categoria.class); setEstado(EstadoABM.NUEVO); } ... }

Thanks in advance!!

Someone correct me if I am wrong but I think java treats an array as an object. That is to say, an array is a subclass of an Object and therefore inherits all the methods that the class object provides.

What does the reset perspective do exacly?
I am asking this because yesterday I download something from a SVN and run it and get a NoClassDefFoundException on a code no longer exists, and I reset the perspective and run it again and the error was gone.. an it worked all right.

I am confuse as why this is. Maybe is a common thing and someone can explain me why..

Thanks in advance folks...

I made a simple web using j2ee that runs on tomcat 6.0. I got some hosting in the web but it did not use tomcat.. what can I do? are there any hosts that provide tomcat or should i install it on that web hosting service?
