Hello everyone, I'm a developer pretty much experienced in web development (HTML, JavaScript, PHP, Django, Ruby on Rails). I have just recently taken on Java (read "Core Java" and the SCJP 6 book) and I now want to start with J2EE. I need a book that will go through the most important aspects (EJB/JSF/etc., I know the buzzwords :) ) of ...

I don't really know how to perform deployment from offline development to live webserver correctly in web development. I mostly resort on intuition, but this is more or less what I did until now: I have a web application in python, or php, and I am hosting it on a live webserver. I use an offline development version whose source is under...

These flash objects are hidden, because I need to save flash as picture and flash must be "visible", because otherwise I cannot save image. My flash objects are Open Flash Chart 2 charts.

I feel a little silly for asking this since I seem to be the only person in the world who doesn't get it, but here goes anyway. I'm going to use Python as an example. When I use raw SQL queries (I usually use ORMs) I use parameterisation, like this example using SQLite: Method A: username = "wayne" query_params = (username) cursor.ex...
Hi, Suppose I allow my users to submit a form containing some text fields (I'm not talking about passwords). My users would occasionally use non-ASCII characters like Russian, Chinese, etc. so I use UTF-8 charsets in my database. The question is, should I really allow all of the possible UTF-8 characters? I had a look at the ASCII table...
I set up an A/B test which required a fairly large amount of data to be stored in a cookie temporarily. While testing my code, I managed to get the cookie over 4kB. Safari set the cookie. On the subsequent page load, Apache returned an error since the cookie was too large. I tested this on Firefox as well and it simply ignores the cooki...
What are examples of well designed functional (as opposed to object oriented) web apps that make their source code available? I am currently studying the Hacker News source but I'd like to see some other non-trivial examples, ideally in clojure. For MVC there are lots of Rails and PHP apps, frameworks, and tutorials to study - what is t...

It is possible, from a servlet, to obtain if a visitor of my site is coming from search engine results page? If yes, is possible to obtain the query string? Thanks in advance EDIT: Thanks...
How important would you say it is to know how to develop Flash applications (not games) if you're looking for a job as a web developer today? The essentials are of course HTML, CSS and JavaScript. A few years ago virtually everyone (as in every non-programmer) wanted Flash on their home page, possibly even with intros with broken "skip ...
Hi all, I'm struggling to figure out the correct way to do something in MVC which wouldn't be difficult in WebForms, and I'm hoping someone will be able to point me in the right direction. Basically, I am displaying a table of data and the user should be able to select zero or more rows. When they press submit I want my controller to ...

Here's my problem: I am disturbed by the "impedance mismatch" between what graphic/web designers actually produce, and what is needed by the standard ASP MVC view engine. Basically there is no way to visually design a view i.e. the output of an action. No WYSIWIG designer. The only way to go from a static HTML design to an MVC app is b...

Hello everyone, I have a website with a top panel and a body part. The top panel can be toggled between hidden and shown. The body part should contain the actual content of the website. As I don't want to hard-code every single site, I would like to stay with the panel and only reload the content. This seems to can be done using AHA...
