Hi Chris,
thanks for your reply. I just wanted to share this exception with every one.
I kept getting error "org.apache.taglibs.standard.examples.beans.Name does
not have a readable property firstname " while workgin on lab lab 4006_el*.
*
**
* <td><c:out value="${person.name.firstname}"/></td>*
I had not declared class Name as public. It was a silly mistake but costed
me couple hours to figure out.
public class Name{
private String firstname;
private String lastname;
Name(String fname, String lname){
firstname = fname;
lastname = lname;
}
public void setFirstname(String fname){
this.firstname = fname;
}
public String getFirstname(){
return firstname;
}
public String getLastname(){
return lastname;
}
public void setLastname(String lname){
this.lastname = lname;
}
}
Preet.
