Re: Accessing action error problem
You can use the attached JSPs to display all the attributes in the request.
Just look for the attribute that stores the errors. In general when I was
starting with Struts I found the attached JSPs very helpful because you can
see the types of information Struts stores for you and where it is stored.
Also, if you look at the Globals class the locations for many of these
attributes are recorded there. I just find it easier to look at the actual
attributes in the request using the attached JSPs rather than hunting
through the javadoc of the Globals class.
