RE: Auto execution of an action on page display
Small point but I think the restrictions on welcome-file depends on the app server / web container that you are using. I've noticed this restriction with jboss/jetty myself but welcome-file-list welcome-filewelcome.do/welcome-file /welcome-file-list works with exteNd. Not sure if I am getting away with it on this platform or its a bug in other platforms.

RE: Automatic refresh - IS THIS POSSIBLE?
Valli I've done something similar before in an intranet application, outside of struts. I had a page that displayed Please Wait and in that page I used meta HTTP-EQUIV=Refresh specifying the URL of the servlet that took a long time to run. I used a low refresh time (0 perhaps) and it seemed to work ok. Check out the meta element in some HTML reference. However you are of course wasting time here with all these requests. It worked ok on an intranet for me, not sure about an internet app. Perhaps there's a better way. Still there's no reason why you couldn't use this technique with struts.

HI, We are using the struts tiles framework in our project. There is a particular request that consumes a lot of time (20 seconds). Instead of showing a blank page is it possible to show a Please Wait message while the processing is happening in the background. Then when the processing is over the page should come up automatically. IS THIS POSSIBLE?

RE: Automatic refresh - IS THIS POSSIBLE?
Cool Much more complete answer than mine but still not a great idea, and has the same downsides as the meta tag stuff, unless I am missing the point. The processing servlet, the process that takes a long time, is only fired off once the user has downloaded the please wait page and executed the java script. Perhaps I am worrying over nothing but what would be real nice is to be able to fire off the long job first, then display the message, then somehow connect up to the long job. Perhaps you could do something with threads to fire off the long job. or maybe I am making this just a little too complex!

RE: dynamic local message / dynamic error codes
Marcus
Localisation is done as per the rest of the app. So for me I have:
ExceedsAvailable=Exceeds available quantity ({0}) in ApplicationResources.properties
and
ExceedsAvailable=Quantita` disponibile superata ({0}) in
ApplicationResources_it.properties
The dynamic message would be something like:
errors.add(amount,new ActionError(ExceedsAvailable,
new Integer(productinfo.getAvailableToOrder())
));
there's a whole set of add methods to accomodate different numbers of parameters.

Can anyone explain to me how to create dynamic localized messages - for

Of course you do not want that. Can the tag html:html check if a html has already been opened, and decide not to output its (unneeded) html tag.

RE: [Struts Tip] #15 Use chained exceptions. Design consideration.
Exception handling in Java is neat when we know what we are doing. However junior
developers often find themselves with exceptions that they aren't really expecting and
don't know what to do with. With no direction from others its all to easy to use
System.out and I have even seen:
catch(Exception e)
{
}
I think this is why the C# guys made their exceptions more like our runtime
exceptions. You don't have the explicit declaration of what exceptions are thrown but
it doesn't force inexperienced developers to end up writing stuff that we wouldn't
want them to do. All interesting stuff but not sure what it has to do with struts.

IMHO 2 traces in the log are better than 0 - the important thing is that you
have something you can look at when debugging. It is of course important
that the business object still throws the exception even if it logged it
(which is indeed what you are doing). (Ive had the misfortune to have to use
objects developed by a third party that log (often to System.out)
exceptions they generate and then dont throw an exception back at my code -
just return a null or something equally useless. Its a real pain I can tell
you...)
Of course components using your object will (should!) probably want to throw
their own exceptions too that nest that thrown by the object as they will
want to record information about their state and what they were doing when
the thrown excrements trajectory caused it to collide with their rotary
atmospheric impeller... (And thats info that the business object won't have
but that you will also want for debugging)

Hi Ted and all in the list,
I´m using ChainedExceptions in my applications, but in my case the
Business Object is using the logger from Log4J. When an exception occurs,
the Business Object logs a message before throwing a new exception with the
original exception chained. I think this is important for application
traceability, the object does not depend on others layers to log his own
problems. If my Business Object is a component, maybe the component user
will log the stack trace, having some redundancy of information. I would
like to hear from the group opnions about this design approach.

Assunto: [Struts Tip] #15 Use chained exceptions
Many Java mavens recommend that business objects throw their own
exceptions. Internally, a component may catching a SQL or IO
exception, but what we really need to tell the user is that a data
access error occurred. Of course, at the same time, you do not
want to sacrifice any detail from the original exception.
Retaining detail from the exception can especially important in a
layered, multi-tiered, or multi-platform application.. The
business component may not have direct access to the log, and the
exception is its only way of telling us what went wrong.

RE: Opening PDF file: Problem and Solution
Neil I wonder if your image/jpeg files displayed ok in Netscape? Its a couple of years ago, nothing to do with struts, but I had a servlet, serving up images, that was not setting the image type correctly. I was serving jpegs, giff etc. but the servlet had hardcoded image/gif. Internet explorer somehow just coped with it and displayed the images. IE seemed either very lax about it or really smart depending on your point of view. Netscape 4.7 just wouldn't display anything.

We got it working but are still unclear as to exactly the reason. Up front I'll mention that we are using sub-applications. We had an action which places a PDF file in the form of a byte[] out on the ServletOutputStream. For some reason the file would not display in the Acrobat plugin. The IE dialog to open or save the file would instead appear. At this point we were able to save the PDF to the client machine, but still remained with the problem of not being able to view the PDF in IE. Now trying this same thing using just a default app worked fine. But we had to make it work using a sub-app. Now comes the confusing part. Streaming out JPEG and Word files worked just fine in our sub-app. Of course, for all three files we are setting the appropriate contentType on the response. We then thought that there might be a problem with the sub-app's configuration. We noticed that in the struts config file, through the controller element, we were setting the contentType to text/html. For some reason, removing the contentType allowed the stream to be opened in Acrobat. It seems that the contentType setting in the sub-app was overriding that for application/pdf but not for image/jpeg or application/msword. Does anyone know why this would be the case?
