BlackBeltFactory.com is a website for online exams and distance/coached e-learning. I love it! and encouraging all my friends to visit it. A new feature "I believe it is new" has been launched to help shy people who can't request training from their managers :-)


BBF "BlackBeltFactory" build a marketplace for Java training, the portal has a very cool Java courses and anyone can be a coach and get paid for coaching students by the students!


Student can now ask their managers indirectly to offer them training :) check this course page where you can let the system notify your manager about your need for this course, even with the coach name and its rate ;) selecting me will make me happy for sure.


Believe it or not but with this blog post I can earn more contribution points at the website so that I can take more exams for free!!



JDC 2010 has been recognized from 90 country. The attached report could be useful for sponsors and compaines to know who is looking for JDC. Also it will give you indication about the countries interested in Java technologies in Africa.


Spring Roo, a quick note Blog

Posted by ahashim Feb 12, 2010

I was going through the documentation of Spring Roo, version 1.0.1 while preparing a talk for JDC 2010 about the Spring Roo .. No need to mention the Roo is awesome, amazing and not Magic :-)

Ben Alex       , Stefan Schmidt did a great job really in this project. Smart architecture!

"The automated startup-time scan is also very useful as you upgrade to newer versions of Roo. Often a new version of Roo will incorporate enhancements to the add-ons that generate files in your project." check more on Roo documentation . This is very useful, and once there is a new version from Roo, developers will participate in testing it by just running the roo shell in their project's directory!

Spring Roo, I like it :)

 I found a cool feature in Google Chrome browser and would like to thank who did it and share it with you :-)

It is "Reopen Closes Tabs" it is available in FireFox using the same short cut but founding it in the right click menu is much easier and visiable to the user. 

Due to some limitation on my business laptop, Firefox is crashing all the time without hope to get it fixed and company internal web sites (10's) is supported in IE6 only and could not upgrade to IE7 so I had to live with Google Chrome as much as I can, I found it  very good.


I did a couple of presentation on IEEE Open Source week at Cairo university, Faculty of Engineering. The power point presentation are attached, and if any one has a question send me hashim {at} egjug.org EGJUG Session

Usually if you are working in a "big" project and doing a code review; if you have a vendor who develop some application for your company; if you have a fresh graduate developer ... you will find a lot of bad-practices in the code being written! I don't like to see System.out.println() in the code .. because simply, it doesn't appears in the log files!!! As a solution, you can use Aspects to figure out the pointcuts in the code which uses "SYSO" and the advice will be to log the message yourself. Let's have a look into the code and how this will work:- 1- the idiot code will be like that aop1.PNG as you see, the method add() will print some info the default output stream which is the console. This method is called from the main method. If you are an eclipse user, you will notice that there is a small orange arrow on the left side of the code editor referring to the line of code uses "SYSO"; we will back to this arrow after while ;). 2- We will now create a new aspect to solve this problem, the BPAspect will looks like the following:- aop3.PNG to define a pointcut to SYSO, the pointcut definition will be pointcut syso():call(* java.io.PrintStream.print*(..)); which means: define a pointcut named syso and get all places which call a method print,println as a members in the PrintStream class, take any argument and return any value. then, mark the called for this method as warning in your code and display this message "Don't use SYSO" declare warning:syso():"Don't use SYSO"; then, how to log the message? the advice will come to do this job after():syso(){logger.info(thisJoinPoint.getArgs()[0]);} 3- What about the orange arrow? it indicates that there is an pointcut which this line matches with. There is a panel also shows the aspects which reference the code in this class aop2.PNG on the other side, if you open the aspect code, the panel will show the code referenced by the aspects. aop4.PNG you will see also that there is a warning message in this line aop5.PNG 4- Now, we can run the application to see how it will work It will print the to the console Add 1 to 2 2008-07-24 14:28:22,828 [main] INFO  BPAspect - Add 1 to 2 and prints to the log file 2008-07-24 14:28:22,828 [main] INFO  BPAspect - Add 1 to 2

Beside Java ... Flex Blog

Posted by ahashim Jun 10, 2008
Few months ago I did my Hello World Flex, I used Adobe Flex Builder and founded it interesting to produce RIA. After than I tried a simple application for file download and discovered some features in Flex. Now, I came with a new project and decided to use Flex to do the job. What is my project? It is a small and smart product catalog with search facilities and customer reviews. Why I decided to make this site with Flex? Java is not suitable because of the hosting issue, finally I want to upload my application in my cheap host which supports PHP only. Why not PHP? because I plan add this small project to a current projects, some of them developed with PHP and other with ASP. I thought about Flex to make it easy to plug to any website The first problem I got is the DB connectivity, there is a way to connect to DB through PHP code or Java, but I didn't like the idea; it will be the same problem again. I asked one of my friends, he is a Flex fan and he told me about a new project which add the feature of DB connection from Flex. The Action Script SQL it is a very new project and tried it yesterday .. it works well as early beta version.
