Re: struts testcase... NullPointerException...
Hi,
In my case the problem was caused by the default validation routine in ActionForm. If this method is not overidden in your code then the default method returns a null and this seems to be th root of the null pointer problem.
I overrode this method as follows:-
public ActionErrors validate(ActionMapping mapping,HttpServletRequest request)
{
return new ActionErrors();
}
This appeared to cure the problem.

This error might be becaue in ur struts-config.xml u have not specified the
form bean.
In ur
u have the logical name for Form bean for that Action class
Check inside the tag
whether the form bean for the request is there or not.
Form Bean bein g accessed and given null pointer can be because it is not
populated when the form is submitted. This can occur because u might not have
associated the form bean with the request in struts config file and only
associate the request with action class or Maybe u have not given the complete
name inclufin gpackage name /relative name whatever u are using.

Hi Deryl,
It's not causing me any great issue at the moment (on 1.5) so no panic for the patch.

If it is not fixed, or if you guys are using v1.5,
let me know, and I'll post a patch. I'm sorry to
be so absent, but my job is kicking my ass right
now.

You should not have to change the code to test it,
it's true. And this should be fixed in the 1.6
version of StrutsTestCase -- specifically, addressing
the perfectly valid case when validate() returns
a null value.
If it is not fixed, or if you guys are using v1.5,
let me know, and I'll post a patch. I'm sorry to

Hi Alan,
Thanks for the solution. My problem too got solved
when I override the validate function in the action
form. But I have a question:
1. Why should one change the actual code for the sole
reason of being able to test it? The application works
fine even if "validate" method is not there.
Thanks,
balki
