This is a quite frustrating job. Whatever you are doing, even if you are very careful during the development, you are going to have a multitude of bugs. That is why the role
- [RichFaces is too greedy](https://www.logikdev.com/2009/11/17/richfaces-is-too-greedy/) - For my first post, let's talk a little bit about RichFaces.

- [Be careful of SKIP_COMMENTS](https://www.logikdev.com/2009/12/01/be-careful-of-skip_comments/) - In the early days, we used to hide JavaScript code from old browsers that do not support JavaScript. The way of doing this was to put a one-line HTML-style comment without the closing characters immediately after the opening tag and put //--> at the end of the script. For example: However if you are
- [Onclick event is not fired on IE](https://www.logikdev.com/2009/12/08/onclick-event-is-not-fired-on-ie/) - I am pretty sure everybody knows that Internet Explorer has "a few" bugs... :roll: You didn't? 8-O Alright, better to stay on your little cloud and leave this blog right away!

- [How to monitor your Java application](https://www.logikdev.com/2009/12/17/how-to-monitor-your-java-application/) - It is very good to have your application and your database running on a Linux or Windows server, but who will tell you if your website is down? Who said "the users"? 8-O No, you won't look very professional if you wait for a user complaint. What you need to do is to monitor your
- [Deploy your app to the root context](https://www.logikdev.com/2010/01/06/deploy-your-app-to-the-root-context/) - This is an easy trick which I am sure most of you already know. Let's take a Java application called MyAddressBook. Its generated war file could be called myaddressbook.war. By default, when you deploy this web application to Tomcat, the URL to access it will be http://localhost:8080/myaddressbook/. And if you point a domain name such

- [Locale settings for your cron job](https://www.logikdev.com/2010/02/02/locale-settings-for-your-cron-job/) - Do you get special characters problem when executing your bash script from a cron job? And does the same script work fine when it is directly executed from the command line? If yes, continue reading this article! ;) The reason of this characters problem is probably because of your locale settings. Indeed, If you try
- [Why GROUP_CONCAT returns BLOB?](https://www.logikdev.com/2010/02/11/why-group_concat-returns-blob/) - Last week, when using the GROUP_CONCAT() function on a MySQL database, I got an unexpected result. :( Indeed, instead of getting my result as VARCHAR types, I got it as BLOB types! For information, a BLOB is a binary large object that can hold a variable amount of data: http://dev.mysql.com/doc/refman/5.0/en/blob.html Because BLOB values are treated as
- [Apple UK keyboard layout for Windows](https://www.logikdev.com/2010/02/18/apple-uk-keyboard-layout-for-windows/) - Because I am now working on a .Net project and I don't want to work on a PC ;-) , I decided to install Windows as guest on my Mac in VirtualBox. Everything works perfectly fine except that Windows doesn't like my Apple keyboard. What a surprise! :roll: After a quick search on Google, I
- [limitToList attribute prevents flashing](https://www.logikdev.com/2010/03/02/limittolist-attribute-prevents-flashing/) - If you have some elements (or even the whole page) that flash/twinkle using RichFaces, it probably means that these elements are AJAX-rendering. The question is by whom and how to fix it? A lot of tags in RichFaces can AJAX-render elements such as: On the above example, the JavaScript function updateName will AJAX-render the element which
- [How to personalise the URLs with Faces Navigation?](https://www.logikdev.com/2010/03/24/how-to-personalise-the-urls-with-faces-navigation/) - This is an important question if you want to have search engine friendly URLs on your website! But unfortunately, the solution is not straightforward with JavaServer Faces (JSF). :( First of all, for security reason JSF doesn't allow you to use the GET method for your forms. I didn't really understand why but this is
- [The message tags of MyFaces and RichFaces](https://www.logikdev.com/2010/05/06/message-tags-of-myfaces-and-richfaces/) - Working on an application using MyFaces and RichFaces, I had no choice but understand what is the difference between the message tag provided by Myfaces (h:message) and the message tag overridden by RichFaces (rich:message). These tags allow to display information about the first FacesMessage that is assigned to the component referenced by the "for" attribute.
- [Validate your EAN barcode](https://www.logikdev.com/2010/05/13/validate-your-ean-barcode/) - On one of the applications I am working on, I had to validate an EAN (European Article Number) barcode.

It found validators in different languages but none in JavaScript. :(
- [Using the 'date' command in your crontab](https://www.logikdev.com/2010/05/25/using-the-date-command-in-your-crontab/) - Crontab, as most people know, enables users to schedule commands or shell scripts to run periodically at certain times or dates. The other day, this very useful Linux tool gave me a hard time! :( Indeed, one of my commands wasn't working in cron but was working perfectly fine when written in a shell console.
- [Image manipulation in VBScript](https://www.logikdev.com/2010/06/09/image-manipulation-in-vbscript/) - I am back on Windows development. It is not what I prefer but still, it is development so I am right here! ;) My task was to upload an image from a website (nothing difficult there) but the application has to resize and crop the uploaded image before saving it on the hard drive in
- [How to configure JSF to get the browser Back button working](https://www.logikdev.com/2010/06/23/configure-jsf-to-get-the-back-button-working/) - Lately, I had a problem with one of my JSF applications which is using RichFaces. The problem was happening when the user was hitting the browser Back button. Well, you would say that it is a usual problem in web development. But still, because we cannot disable the browser Back button, the web application needs
- [Use ServerXMLHTTP through a proxy](https://www.logikdev.com/2010/07/07/use-serverxmlhttp-through-proxy/) - The other day, I was trying to use the ServerXMLHTTP object. For information, this object was created to allow you to establish server-to-server HTTP connections. The code I firstly wrote looked like the following: with sURL the URL to call and sParams the parameters to send with the URL. The problem was that oXMLHTTP.responseText didn't
- [Relation between TortoiseSVN and locale](https://www.logikdev.com/2010/08/15/relation-between-tortoisesvn-and-locale/) - The other day, I got stuck on a problem with TortoiseSVN for about half a day! 8-O Yes, I know, it is a pretty long time to get a simple subversion client working... The error I was continuously getting was: Nothing else! Nothing in the log files on both the client and the server. :(
- [Validate file size prior upload](https://www.logikdev.com/2010/08/26/validate-file-size-prior-upload/) - If I ask you what is the most complex thing in HTML, what would you reply? For me, it would be the file upload (or maybe character encoding, but this is not the topic! :P ). One of the problem around the file upload functionality is that there is, no matter what, a file size

- [loadBundle's behaviour with JSTL tags](https://www.logikdev.com/2010/10/02/loadbundles-behaviour-with-jstl-tags/) - Let's start with a bit of knowledge. f:loadBundle is a JSF tag which loads a resource bundle and saves it as a variable in the request scope. The RichFaces a4j:loadBundle tag is a substitution for the f:loadBundle tag and allows to use reference to bundle messages during the Ajax re-rendering. When I discovered the RichFaces
- [The selfRendered attribute](https://www.logikdev.com/2010/10/12/the-selfrendered-attribute/) - This is an interesting problem related to the RichFaces rich:suggestionbox tag. Let's take the following code: If you use the code above as it is, the whole page is going to be processed each time the suggestionAction is called. And because the minChars attribute is set to 1, the action is going to be called

I then wanted to automatically synchronise the internal time with some NTP Pool Time Servers. But, for
- [Permissions ignored with Samba](https://www.logikdev.com/2011/01/17/permissions-ignored-with-samba/) - After the issue regarding the ntpd process, I encountered another problem with my D-Link DNS-313. This time it was about permissions problem using Samba. Because I have multiple user accounts sharing the same data, I added the following lines into the Samba configuration file (smb.conf): With these properties, a user will have the permission to

- [Detect if JavaScript is enabled](https://www.logikdev.com/2011/04/19/detect-javascript-enabled/) - Because of the emergence of Ajax, people don't disable JavaScript much nowadays. I don't know the percentage of people having disabled JavaScript. It is likely under 5%. But if you have a website visited by millions of visitors every month, even 1% is matter! This is why I wrote the following code: The text under

- [AVG function returns 0.9999](https://www.logikdev.com/2011/09/15/avg-function-returns-09999/) - This one is a very odd bug! :-| For some reason, the AVG function from MySQL is always returning the value 0.9999 instead of the average value. This has been experienced on MySQL 5.5.12 hosted on Amazon RDS (Relational Database Service). However, the exact same query executed on MySQL 5.1.28 is returning the right values.

- [MD5 generates 31 bytes instead of 32](https://www.logikdev.com/2012/12/12/md5-generates-31-bytes-instead-of-32/) - I wrote the following method to generate MD5 hashes: This method takes a String and outputs a 32 character hash. However, depending on the value of the parameter, this method outputs a 31 character hash instead of 32. Why is that? It appears that it is because the leading zero is missing. But the question
