I would like to list the Egyptian Java developers who are contributing to OpenSourceSoftware

In part 1 we talked about the basics and terminologies of cache and we have also shown replacement policies , in part 2 we implemented some of these famous replacement polices and now in this part we will continue talking about the implementation of two famous algorithms which are LFU and LRU.we we will get to see how to implment the LRU in different ways and which way is better for more info visit

In one of my pervious posts I talked about my mistake that I wasn’t use any version control sysetm to control my work
VSS was so boring for me as ajava guy it’n not compatible with eclipse as far as I know ,so I dig through the internet to find a suitable tool for me
And I found my one CVS
this article consists of 2 parts, first part is talking bout CVS
Part 2 is talking bout How to use CVS wirth eclipse

*for those who do know what is version control i found a nice story Published by FCI_H guys talking about Source control .

What’s CVS…?

CVS is the most popular version control system in the free software community, used by Netscape,, many Linux projects, and others.

Initially, CVS was designed to provide version control for a group of developers working on a single machine. There was a CVS repository somewhere on the file system, and every developer working on a project had to have a read-write access to the repository files, including auxiliary files used by cvs program itself.

How to call Excel Macro from JAVA enterprise

After trying more, find a satisfied solution,

since excel macro is vb code, since we can make a vb script file called from java and it calls excel macro

Example:

make a script file as content is

Dim objXL
Set objXL = CreateObject("Excel.Application")
With objXL
    .Workbooks.Open ("File_Path")
    .Application.Run "Macro_Name"
    .Application.Quit
End With
Set objXL = Nothing

and save it as calling.vbs

in java you can call it as Runtime.getRuntime().exec("cmd /c start calling.vbs");

 Enjoy it,

  I'm thinking about one place to collect/include reference for all the Tools, Frameworks, IDEs, and Technologies; some place to act as technologies/tools/frameworks wiki as well as it contains short description about this tools and what are its strengths from the writer experience.
and instead of googling and wasting time in things searched about million of times until one found his suitable IDE/Tool/Framework, I thought about creating such page here that growth by time and act as reference for all.
I know that many people will wondering why do it here. as some of the information listed here can be found for example on wikipedia.
But some are not found and even if u can go and create page for it, there exist the feature of grouping and collecting the java related tools, IDEs, ... etc.
so let's start such page. and I hope all share his own knowledge/experience/opinion in this page.

mainly we have two Sections:

     1.  Integrated development environment (IDE):-
           also known as integrated design environment and integrated debugging environment, is a type of computer Software that assist computer programmers to develop software [ wikipedia ].

In this article I will try to reverse engineer a postgres data base and I think any other database will be the same with small modifications in the config and properties files.

ok lets start.

I will use andromda:schema2xmi plugin to achieve this task.

Prerequisites:

1. Maven version 1.
2. In brief a working andromda environment.

Requiered steps to generate the xmi file from our postgres data base are 5:

1. Generate an AndroMDA project using Maven.
   
2. Add the PostgreSQL Mappings file.
   
3. Modify the project properties.
   
4. Add dependency to Postgres jdbc drivers.
5. Run schema2xmi.

1. Generate a standard J2EE project. as down million of times:

Yes, we must retire some old friends. Management says it's time to drop these code names and develop a new project naming system around our open source model. Better now than after Dolphin get's firmly entrenched – and as for Mustang, well it's almost done anyway. more
