java.lang.IllegalArgumentException: No destination bean specified

807589Jan 4 2007 — edited Oct 3 2008
I am using MyActionForm extending ActionForm and created an instance of that in the action class.

I am writing.. 
BeanUtils.copyProperties(actionForm,myActionForm);
actionForm....ActionForm obj in the action.
myActionForm ... Bean(form) obj that is extending ActionForm.

I am getting the folowing exception... 
java.lang.IllegalArgumentException: No destination bean specified
I have set some the values of the form and forwarding to a JSP page where I have the matching propertiees.

I have used the copyProps many time and never got the above exception.

Did a lot of check and could not find what is going on.

Appreciate help.

Are you sure you don't have the arguments reversed? the Dest should be first and the source should be second. Just a thought.

My destination is ActionForm obj in my case actionForm and the source is Form bean that has the matching props set.

I logged the values in the form bean they are also printing the values i assigned.

Pl suggest

Well, are you sure actionForm is not null at the point you are copying to it, an dthe myActionForm also is not null?

According to the API, This method throws an IllegalArgumentException if either of the arguments is null.

I would do a System.out.print() just prior to the method call to make sure they aren't null.

I have fixed the issue.

Very silly mistake I made.

I forgot to add name =MyForm in the struts-config.

Sorry to bother the forum experts.

Lesson Learnt....I feel pity on my self.

You must have destination object null; Just initialize that and try I am sure it will work.
