Your example:
private void prepopulateForm( ... )
{
// copy properties from the DTO to the form
if ( form != null && contact != null ) {
DynaActionForm dvForm = (DynaActionForm) form;
BeanUtils.copyProperties( dvForm, contact );
//manually deal with prospectName since it's called prospectNameOrId on
the form
dvForm.set( "prospectNameOrId", contact.getProspectName() );
}
}
Does not work for me. I get this:
ERROR [com.bay4.jsp] [org.apache.taglibs.log.LoggerTag] 2003-12-19 09:30:41,285

Here is a snippet of my code:
HttpSession session = request.getSession(false);
User user = (User)session.getAttribute(Const.USER);
DynaActionForm dvForm = (DynaActionForm) form;
BeanUtils.copyProperties( dvForm, user );
return mapping.findForward("showdetail");
I have this defined in my struts-config.xml:
<form-bean name="userEditForm"
type="org.apache.struts.validator.DynaValidatorForm">
<form-property name="id" type="java.lang.String" initial=""/>
<form-property name="firstName" type="java.lang.String" initial=""/>
<form-property name="lastName" type="java.lang.String" initial=""/>
<form-property name="email" type="java.lang.String" initial=""/>
<form-property name="phoneNumber" type="java.lang.String" initial=""/>
<form-property name="password" type="java.lang.String" initial=""/>
<form-property name="passwordRetype" type="java.lang.String" initial=""/>
<form-property name="companyId" type="java.lang.String" initial=""/>
<form-property name="roles" type="java.lang.String" initial=""/>
</form-bean>
Plus more stuff in validation.xml. Won't go into all that. How is the connection
made between what I have defined in my struts config and the copyProperties method.
At that point, I have not even accessed the form. The form object is just an
ActionForm. I'm missing something here.

Look at the signature of the execute method. The form bean gets created
before execute is called, and passed into the method. The code I posted
is from a working app, I only deleted the try/catch and some logging.
Configure logging and turn it up to debug, Struts and the other Jakarta
components are very verbose. Or run it in a debugger and see what
really happens-- I learned more in 2 hours with Jswat than I had in
months of reading and experimentation.
