Output problem in jsf

Question

hello, i'm new to jsf and eclipse...
i managed to retrieve data from a database (i printed it to my jboss console so i'm sure i've got it right), and am trying to put it in my next jsf page..... with one item of data (numAdm, see blow) from the bean it works fine, with another (nomPat) impossible, why !!??
in the console i get the error message : javax.faces.FacesException: Bean: com.loginMG.bean.PatientBean, property: nomPat
here is my jsf code :
<td>
<h:outputText value="#{bundle.user_password_label}" />
</td>
<td>
<h:outputText value="#{PatientBean.numAdm}" />
</td>
<td>
<h:outputText value="#{PatientBean.nomPat}" />
</td>
the 2 first work fine, the 3rd gives the error message when i get to the page
here is (part of ) my bean :
package com.loginMG.bean;
import javax.faces.application.FacesMessage;
import javax.faces.context.FacesContext;
public class PatientBean
private String numAdm = null;
private String nomPat = null;
public String getNumAdm()
return numAdm;
public String getNomPat(PatientObject pat)
nomPat = pat.getNom();
System.out.print(nomPat); /* this is correct */
return nomPat;
what's wrong/different between the 2 ?
fyi i got numAdm from in input field in another jsf page, and nomPat from a database, but this shouldn't interfere ?
thx for helping out,

Answer 1

the important thing is that it returns nomPat, no ?
actually no :)
JSF will take this expression
<h:outputText value="#{PatientBean.nomPat}" />
and evaluate to to
patientBean.getNomPat()
that is why managed beans must follow the Java Bean standard
i.e zero arg constructor
access varaibles through getXxx() and setXxx() methods
