Problem with PropertyUtils.copyProperties(...

["Juan Alvarado (Struts List)" <ju...@manduca.com>]

I am using a DynaActionForm:
	<form-bean name="userForm"
               dynamic="true"
               type="org.apache.struts.validator.DynaValidatorForm" >
               <form-property name="id" type="java.lang.String"/>
               <form-property name="firstName" type="java.lang.String"/>
               <form-property name="lastName" type="java.lang.String"/>
               <form-property name="dispatch" type="java.lang.String"/>
    </form-bean>

I want to perform the following in my action:
	 DynaActionForm f = (DynaActionForm)form;
       User user = new User();
	 try{
	 	PropertyUtils.copyProperties(user, f);
	}
	catch(Exception e){...}

My user object is composed as follows:
	package ob.users;

public class UserDTO {

    private String firstName;
    private String lastName;
    private Integer id;

    public java.lang.String getFirstName() {
        return firstName;
    }
    public Integer getId() {
        return id;
    }
    public java.lang.String getLastName() {
        return lastName;
    }
    public void setFirstName(java.lang.String value) {
        firstName = value;
    }
    public void setId(Integer value) {
        id = value;
    }
    public void setLastName(java.lang.String value) {
        lastName = value;
    }
}

And I keep on getting Error creating DTO -- java.lang.NoSuchMethodException:
Unknown property 'class'

I am relatively new using the bean utils package and I didn't find anything
in the archives. Can anyone tell me what I'm doing wrong.

Thanks in advance

Juan,

I think I made a mistake (sort of) when I shared some of this code. I
didn't realize you don't need the dispatch field (or whatever you want
to name it) in the actual DynaActionForm or an ActionForm. I notice
that the UserDTO doesn't have the dispatch member in it, so maybe the
PropertyUtils is looking for to convert that field from the
DynaActionForm? (Not sure though just a guess since I haven't used
PropertyUtils ). Try just removing the
<form-property name="dispatch" type="java.lang.String"/>
from the DyanActionForm and see what happens.
