Building Apache Tomcat 8



Apache tomcat is a well known web server among JavaEE developers. Lot of user's tend to download the binary distributions. But if you are interested in building tomcat from the source code then you have visited the right place. Enough chit-chat let's dive in.

Requirements

 Lets get started!

Setting up JDK 1.7 
First of all you need to install JDK and set up the environment variable JAVA_HOME. I'm assuming that you might have already done this. If not there are web sites that teaches you this step.

Once you have  the next step is setting up Apache Ant. 

Apache Ant (Another Neat Tool)
Since we don't come across tools like Apache Ant I'll give you a brief description what it is.
Apache ant is a build tool developed by James Duncan Davidson. It was developed as a solution to problems and compatibility in Apache Make Tool. Apache Ant's primary mission was to support building Apache Tomcat but later it was promoted to a independent project in year 2000. I think that enough for a small talk about Ant.

Once you have downloaded Apache Ant you will have following  directories.
(Note: I have downloaded Apache Ant 1.9.7)
 then couple of environment variables need to configured.
  • ANT_HOME - Create this variable should points to the directory contains Apache Ant
  • PATH - Edit this variable,Append the path that points to the bin folder in Apache Ant that you download
 Tomcat 8 build configurations

 Your Downloaded source code file hierarchy should look like this.(Apache Tomcat 8.0.3)


Building and running tomcat needs a some library files. These files are not bundled with the tomcat source code. Therefore before diving into building tomcat we need to set up a folder (area) that holds this library files.

 To do so we have to edit "build.properties.default" file. Open the file in a text editor. Find the variable "base.path". And enter the absolute path.(NOTE: the folder doesn't need to created at this step, but make sure you give a legit path)


Building tomcat will require Internet connection. Therefore if you are using proxy settings make sure you do the necessary configurations.
 All Set, Let's Build !

We have reached the finish line.. A simple last step,
open command prompt or terminal. move into the directory. and simply type "ant" without quotation marks.
you will see the libraries and packages are downloading, and then compiling and building. Finally the message BUILD SUCCESSFUL.

One last Toast.

I hope that this was helpful to you to understand and follow the steps towards successful build. Comment if you found any issues or any mistakes I've made. Until next time adios amigos!!

DDoS and DoS Attacks and Tools - Part 1

Note: Following Content is only for educational and White Hat security purposes . History of DOS Attackers Back in 1974, a teenager named David Dennis created the first ever DoS attack. This student was a student at University High School, located across the street from thr University of Illinois at Urbana. He came to know about a command that could be run on PLATO terminals which was used at the Computer Based Learning Center (CERL) of University of Illinois. He was curious and wondered what will happen if a room full of people executed a command of PLATO terminal. When he wrote a program and executed he found out that his program has forced all 31 computers of the  CERL to turned off! After that DoS attacks has spread and DDoS, a new and powerful variant of DoS came in to play. Below are some noted cyber attacks from 1988 to near 2014.from year 2000 DDoS Tools were used for the attacks most of the time. The attacks were in scales from Small tickles to Geo-Political ...

DDoS and DoS Attacks and Tools - Part 2

In this we will go through the rest of the DoS attack types from the previous blog post. I n the latter part we will get to know few infamous DoS attack tools. Please note that how you use these is at you own risk and make sure you always adhere to laws from your governing body. Attacks Targeting Server Resources  In this type attacks the attacker will try to use as mush as server resources so that the server can't handle legitimate requests any more. This type of attacks will target servers memory, buffers and other resources. Attacker will exploit a weakness in communication protocol. There are attacks in this category which can result server to crash or otherwise require a manual reboot to come alive again. Server can be normal server or a state-full device like firewall or intrusion-detection system.  TCP/IP Weakness This is a connection-oriented protocol. One of main consents behind this protocol is that the three way handshake. which uses flag bit...

Apache Spark Small Talk

Image
Apache Spark is sub project of Apache Hadoop. It is developed in University of California, Berkeley. Apache Spark was build for "Lighting faster cluster computing" as it's official web site says. By using Spark some issues in Hadoop was addressed well therefore Spark was popular in no time. It was open sourced in 2010 under BSD license. Main Components in Apache Spark  Apache Spark has a few tightly integrated components as you can see here. As you may understand Spark Core has core functionalities like memory management, task scheduling, fault recovery etc. The main data abstraction Resilient Distributed Data set (RDD) is also defined in the Spark Core. Spark SQL, Spark Streaming Real Time, MLib(Machine Lerning Library), Graph X each component has unique and different functionalities. Since we focus more on Spark Core functionalities and concepts at this stage, we will dive into those in later episodes of this serise.  Resilient Distributed Dataset ...
