Is is OK to use Collections (or sets, lists, maps for that matter)
inside an ActionForm? We are trying to represent fairly complex
multiple-choice items in our forms.

Our application has a form with a multiple-selection item. We implemented it by
including a List in the ActionForm. Each item in the List is a plain-old object, added
from the corresponding Action.
When this application runs in a 2-node cluster, items in the List dissappear at
random. Session r
Unless the tomcat server(s) has fileserver capabilities, you can create
an NFS mount to a fileserver share and have your code create Files
there.
Better yet (IMO), store them in the database as BLOBs so all your data
lives at a single location. The decision depends on what use is given to
those fi
Our users need to upload a file as part of a form submission. We use
struts-upload FormFile, but the application breaks when run in a tomcat

Since the form is session-scoped, FormFile has to be serialized for
sessions to be replicated but we get a NotSerializableException for

Hi,
Our users need to upload a file as part of a form submission. First we
used struts-upload FormFile as one of the fields of the ActionForm. It
worked well until we tested it in a Tomcat cluster.
Since the form is session-scoped, the FormFile has to be serialized for
sessions to be replicated.

Unless you have existing data that cannot be migrated to a relational DB
(or other good reason to keep it as XML), I would advise against using
XML as data source. Simply put, parsing XML is always comparative

Is it possible to prevent a particular Struts webapp from displaying
directory listings? That is, global /conf/web.xml has its DefaultServlet
with listings set to true, thus enabling dir listing for all apps. Can I
then prevent a particular Struts webapp from doing so by setting

We have Tomcat 5.0.16 and were incorrectly placing common jars (such as
JDBC drivers) in /common/lib.
Now we just moved them to /shared/lib (for truly common stuff) and
WEB-INF/lib, but now all applications complain giving a

I assume you ask about an Oracle RAC database.
In that case, the mode is "kind-of" ACTIVE/ACTIVE: What you get is a
single database mounted by as many instances as cluster nodes you have
configured. So every time your application establishes a db connection,
it may be served by either cluster nod
Hi,
What's the preferred way to upload files into a database in a J2EE Web
application?
Is there any way to stream the file straight from the HttpServletRequest
to the database without staging it in the server's filesystem?
Thank you,
Ivan.

Hi,
How can I read from web.xml, say, the application's display name? I've
tried several things, but no luck. This isn't really Struts-specific,
but I'm sure this is an easy one for many of you.
Thanks,
Ivan.

Hi,
We have a form whose last two controls are an html:select and a submit
button. The form posts to an Action to insert records into a database.
Changing the select control causes a page refresh (posting to the same
Action) in order to display other options.
We notice that, if the user submits
