What would you suggest as a good and practical but simple pattern for a soloution with:
HTML + JSP (as a view/presentation)
SERVLETS (controller, request, session-handling)
EJB (persistence, businesslogic)
MySQL DB
And is it necessary to use an own layer of DAO for persistence? I use JPA to persist objects to my DB.
Should I withdraw business logic from my EJB? Sources online all tell me different things and confuses me...
I have a online survey running in Silverlight. Out of more than 1000 onetime users, there are three users than cannot open a combobox on the first page. The control seems disabled and don't react on mouseclick.
Since it is one-time user, they don't wan't to help me with debugging and I cannot reproduce the problem myself.
Any ideas why 1000 users have no problem, and 3 are experiencing all controls like they were disabled?
I'm building a site for streaming online radiostations at http://bigups.dk using jplayer.
The stream causes the browser to build up memory until no memory is left on the client. Is there any way to release this memory via javasript?
We are looking for a secure online solution to access our files stored on Amazon S3. We have about 3K files, mostly media and documents, that we need to make available to our employees on the move. We don't want to develop anything in-house if there is an existing solution.
Please note that our employees are not technologically minded , so a simple web based upload/download GUI would work the best.
I know that different DBMSes support different aggregate functions; for example:
MySQL's aggregates
Oracle's aggregates
I want to get the list of aggregates mandated by the SQL standard. Or, to be more precise, the lists of mandatory aggregates for SQL 1992, 1998, 2003, 2008 and 2011 - with 2011 being the most important to me.
Edit: Of course if I buy a copy of the standards I could compile these lists myself. My question is whether they're accessible somewhere online.
Dear all,

Hi,

MVC is used a number of popular frameworks. To name just a few, Ruby on Rails, ASP.NET MVC, Monorail, Spring MVC.
Are there any equivalent frameworks using any variant of MVP?
Most of the examples I've found online seem to be custom implementations of the pattern rather than reusable frameworks.
Suggestions need not be specific to any particular programming language, my interest is mostly academic.
I am just beginning Haskell, but from all the online tutorials I've found I can't seem to find if there is one accepted way to do a conditional control statement. I have seen if-else, guards, and pattern matching, but they all seem to accomplish the same thing. Is there one generally accepted/faster/more efficient way than the rest?
I am looking for good beginners material on Prolog, both online and printed. I am not only interested in 'learning the language' but also in background and scientific information.
Hi,
I was wondering if it is possible to install or use any online service to measure your website's performance? I've seen many just checking the download speed of images, external files etc. But is it possible to meassure how long asp/php code takes to execute?
I have a site running a bit slowly, and it would be very nice with some app/service guiding where to optimize.
Hi all,
I want to use Flurry to collect some statistics, so I registered and created an app in Flurry. Then, I put the following code in my appDidFinishLaunching:
[FlurryAPI startSession:@"code here"];
Afterwards, I installed the app on my iPhone and ran it - but I don't see any data online. Am I missing something?
And is data also collected from the simulator?
Thanks a lot,
Stefan

Can anyone recommend a decent tool for optimising images other than adobe photoshop, the gimp etc?
I'm looking to optimise images for the web preferably online and free.
Basically I have a client who can't install additional software on their work PC but needs to optimise photographs and other images for their website and is presently uploading 1 or 2 Mb files.
On a personal level I'm interested to see what other people are using...
It's very difficult to find this kind of document online.
I found one in JAVAWORLD, but this one does not cover the jjTree and visiter one.
Does anybody happen to have some links to the tutorials?
I have been involved in JSF + Facelets dev for a month or so. I used composition, insert, define and other tags from facelets. I am finding it difficult to understand what facelets really give me?

is there some online web app which would let me make a vector drawing, and give me the choice to write some text and send it through gmail ?
for the magic to be complete, the web app would save my drawing as png (or whatever) and attach it to the sent email...
i guess i would have to give the webapp my gmail account info so it can send it from my account...

I'm setting up an online ordering system but I'm in Australia and for international customers I'd like to show prices in US dollars or Euros so they don't have to make the mental effort to convert from Australian dollars.
Does anyone know if I can pull up to date exchange rates off the net somewhere in an easy-to-parse format I can access from my PHP script ?
UPDATE: I have now written a PHP class which implements this. You can get the code from my website.
Hi StackOverflow,
I'm trying to group the following string into three groups.
0:0:Awesome:awesome
That being "0", "0" and "Awesome:awesome"
Using this regular expression:
^([0-9]+)\:([0-9]*)\:(.*)$
It works fine on online regex services: http://rubular.com/r/QePxt57EwU
But it seems like .NET doesn't agree.
