Use Photomail to share photos without annoying attachments.
which is a good instance variable
Posted by Carl Smith <cc...@yahoo.com>.
I am designing a new class and wondering what class are a good candidates for the class attribute. I know String, Date, Integer, int, fload, boolean, Boolean all are good for instance variables, but classes/interfaces like Map, InputStream, Iterator are also good instance variable cadidate? Why?
Thanks.

Re: Bean scope...
Posted by Ted Husted <te...@gmail.com>.
After defining a form-bean for an ActionForm
<form-bean name="StatusSearchActionForm"
the next step is to relate the ActionForm to an ActionMapping. The
"name" attribute in an mapping refers to the "name" attribute in a
form-bean.
When a request is made for a *specific* action with the attribute
"name='StatusSearchActionForm'", the controller will create the
ActionForm and put into the context using "StatusSearchActionForm" as
the key.
The message
"Cannot find bean StatusSearchActionForm in any scope"
is probably being generated by a bean:write tag, or equivalent on a
page that was reached without going through an ActionMapping that
referred to the form-bean of that name. The controller only creates a
StatusSearchActionForm when it is told. If the bean doesn't exist,
it's because the controller has not been told to create one.
A point of confusion might be if the StatusSearchActionForm is created
in session scope. In that case, whether the bean exists when a given
action is called might depend on some other action being called first.
Using sessions scope for ActinoForms can lead to a situation when the
error seems inconsistent. Sadly, session scope is the default.
