Question

I got this exception in time of running a web application in java. What does this mean?

exception.name = javax.servlet.ServletException: BeanUtils.populate

Answer 1

I guess you are using something which utilizes Jakarta BeanUtils (like Struts) and some method is throwing an exception.

Following may be reasons for same :

1. The action attribute of an tag must
   match exactly the path attribute of
   the action definition in the
   struts-config.xml file. This is how
   Struts associates the ActionForm
   bean with the action.
2. This error usually occurs when you
   have specified a form name that does
   not exist in your tag. For example,
   you specifiec and ‘myForm’ is not
   the name of a form associated with
   myAction in the struts-config file
3. You get this message when Struts is
   unable to map the data in the HTML
   form to the properties in your
   ActionForm bean. Make sure each of
   the properties on your bean is
   either a String or a boolean. Do you
   have any properties of type
   java.util.Date or other objects?
   That might cause this error. Also
   check to see that you have public
   getters and setter for each of your
   properties.
