Java EE (Java Enterprise Edition) General Discussion

Hello All.

I'm starting a new short-time project and spent a day trying to jump into JSF.

Things I'm trying to do are pretty simple:

1 jsp (faces) that has a combo getting data from a bean (a la struts form).

html:
<CODE>
<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %>
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %>

<h:form id="addForm" >
<h:selectOneMenu value="#{TipoIncidenciaBean.selectedTipoIncidencia}">
<f:selectItems value="#{TipoIncidenciaBean.tipoIncidenciaList}"/>
</h:selectOneMenu>
</h:form>
</CODE>

bean:
<CODE>
package com.sabia.fichatron.faces.model;

import com.sabia.fichatron.db.dao.TipoIncidenciaDAO;
import com.sabia.fichatron.db.DataAccessException;
import com.sabia.fichatron.db.bean.TipoIncidencia;

import javax.faces.model.SelectItem;
import java.util.Collection;
import java.util.ArrayList;

public class TipoIncidenciaModel
{
private Object selectedTipoIncidencia;

public Object getSelectedTipoIncidencia()
{
return selectedTipoIncidencia;
}

public void setSelectedTipoIncidencia(Object selectedTipoIncidencia)
{
this.selectedTipoIncidencia = selectedTipoIncidencia;
}

public Collection getTipoIncidenciaList()
{
ArrayList items;
try
{
ArrayList incidencias = TipoIncidenciaDAO.getTipoIncidenciaList();
items = new ArrayList(incidencias.size());

for (int i = 0, n = incidencias.size(); i < n; i++)
{
TipoIncidencia incidencia = (TipoIncidencia)incidencias.get(i);
SelectItem item = new SelectItem(new Integer(incidencia.getIdTipoIncidencia()), incidencia.getDescripcion());
items.add(item);
}
}
catch (DataAccessException e)
{
e.printStackTrace();
items = new ArrayList(0);
}

return items;
}

public void getTipoIncidenciaList(Collection list) {}
}
</CODE>

I got a ClassCastException:

The faces jsp are called OK through Faces servlet. I can even put a breakpoint to test.jsp to check it.
