RE: Best way of implementing application-specific config objects

[Josh Rayls]

I like to use this method, because I can then use my initalization servlet
for other sorts of initialization items.  For instance, if you have some
sort of scheduler in your app, this init servlet can also take care of
scheduling relevant tasks.  Perhaps you have other services within your web
app that need to be initialized; this servlet can also handle those items.
It's not just a way to load your configuration; it's a way to do
boostrapping sort of items without utilizing the proprietary interfaces of
your app server.

Don't get me wrong.  I love Struts, but I try to shy away from things that
tie me down to a certain framework.  That's why I tend to stay away from the
plugin options.  In my opinion, app configuration is vendor and framework
neutral.  It should work no matter where you deploy and be independent from
any frameworks that you choose to implement.

Hey Josh, you're really fast =)

Well, I thought about doing that (actually, that was my only shot) but 
that would mean creating a servlet that does nothing but calling the 
initialization method of the Factory (or, worse, creating the factory as a 
servlet). That's okay for me doing that, but if there was a better way 
:-)

Thanks!!!

Hi to everyone!

In my project, I  have a XML with some config data, like username, 
password (all connections made from my system to a target systenm must use 

this same info).

I'm a little lost about the best way of implementing this. I thought about 

doing: a  "Config" Factory, that should keep a singleton Config object 
(that should be populated with data from the XML). But I would need a way 
for calling some initialization action for this Factory (like creating the 

Hashtables and so on). How could I do that in a smart way so I don't have 
to check at every call if the Factory has already been initialized?

Sorry if this is a stupid question, but I am far from being a master =)

RE: html:errors tag lost?

[Josh Rayls]

I believe the answer to your question is that a redirect causes a new
request to be made.  Because of this, the errors object in your request is
gone.  It was a part of the old request.  When redirect is set to false,
it's merely forwarding a request and therefore keeping all of the attributes
intact.

While playing with Kevin's action input= suggestion, I found I needed
to mess with the redirect= values.  If I set redirect=true, my
relative paths work fine.

However, I am using the html:errors tag and it seems that it has
gotten "lost", i.e. I do not get my validation errors displayed.

I'm still not entirely clear on how the html:errors tag works, but I
have this in my tile jsp:





And when I have redirect=false, I get things like "Password is
required" in the html, but the url is my .do and my relative paths
don't work and I can't see my images.  When it is true, I don't get
the error text (but the url is what I want and the paths are just fine
- I can see my images).

Sorry for all the questions... Hopefully I'll be able to answer a few
myself some day...

Don't use class scoped variables.  Only use local variables on the stack,

Collection.

RE: Collection Implementation

[Josh Rayls]

Do you specifically need a synchronized Collection?  If not, then it's
needless overhead.  An ArrayList will be faster than a Vector.  A Vector is
synchronized, while an ArrayList is not.

As for which implementation of Collection to use, there are many different
reasons for using various types of Collections.  You can find lots of info
on Sun's site.

that ArrayLists are not synchronized:

Time to refactor again?  I need to be using one of the

I thought you were pulling a gig in London - you are in Sydney?  whatever,
I've noticed over the past year you and me seem to be to only ones working
late nights and weekends (those slackers!).  Anyway, I just ran into a bug I
cannot solve after so many hours and a bottle of good Aussie wine (a quite
tasty Shiraz).  So good-night (morning?) to all, and to all, a day without
bugs.

I am close to comatoseall I see is

Hehe, the only way you would ever catch me awake at such an ungodly hour is
if I hadnt gone home the night before.

Its 1pm here mate, and for once Ive had a decent rest having had to take a
sicky yesterday and having taken the weekend off too. (Sure beats the
previous weekend where I did 26 hours straight at the office)

Reckon I might even be sneaking off home early (8pm) today. :-)

So... what times it over there? Guess you would have done what? 18 , 19
hours straight so far?

IMO, people interested in Barracuda developments should subscribe to
whatever mailing list you publish.  This really has nothing to do with
Struts and, at best, should be posted as [OT].

It would be hard for us to figure out anything without any description
of what really happens.  Do you have an exception stack trace?

You could really help yourself out by setting this up in a JPDA debugger
and really tracking exactly what happens at the point of the error (and
before).

Are you using Struts-EL?  You can't reference EL expressions in Struts
tags, just Struts-EL.

Indexed Properties with DynaActionForm Problems

[Josh Rayls]

Hello,

I have been struggling with this for a couple of days now.  I've scoured the
archives from top to bottom, and I've found some useful tidbits, but nothing
that directly addresses my dilemma.  Then again, maybe I'm just not getting
it!

I get an IndexOutOfBoundsException each time.  I want to be able to have an
arbitrary numbers of rows in the form and then be able to construct beans
from the rows in my action class.

Any help would be greatly appreciated.  I'm going to have very little hair
left when this is done

Code is below:

Action -

// instance variables
ActionErrors errors = new ActionErrors();
Collection c = new ArrayList();
int rows = ((Integer)PropertyUtils.getProperty(actionForm,
"rows")).intValue();

// populate the collection with day parts

PropertyDescriptor[] props =

Rendering in XHTML

[Josh Rayls]

Hello,

I'm having problems getting my browser to render the XHTML properly.  My
doctype is correct, and my page is well formed.  For some reason, when I hit
the page, the DOM is shown in IE 6.0.  I'm running Struts 1.1 on Weblogic
7.0.

Thanks in advance!

Hi,

Is there a property that I can use to get the size of a collection?

Basically, I want to do this:

${resultBean.result.length}

Where result is a Collection.

Thanks for any help!
