jQuery’s popularity in the Ruby on Rails community has been growing in recent months. jQuery, with its unobtrusive nature, has got developers thinking in ways that they haven’t done before. jQuery is doing for the implementation of JavaScript what CSS did for the old school table layouts. Ruby on Rails, with its convention over configuration and full stack, makes it extremely simple (and secure) to get a professional web application up and running. Practical Rails wit (more…)

This book shows how to use SOA and web services to build powerful applications in Java. It teaches the concepts and the implementation with best-practice real-world examples. You will learn to design a sound architecture for successful implementation of any business solution, the different types of architecture, and various tenets of SOA. The book explains the fundamentals and the advantages of using the Service Oriented Architecture in designing your business solution.

In Detail: Service Oriented Architecture provides a way for applications to work together over the Internet. Usually, SOA applications are exposed through web services.Web services have been around for a while, but complex adoption processes and poor standardization hampered their use at first. However, with the adoption of new, simpler protocols such as REST, and major companies supporting SOA, the time is now right to adopt these standards.This book will show you how to build SOA, web services-based applications using Java. You will find out when SOA is the best choice for your application, how to design a sound architecture, and then implement your design using Java.The book covers the important web services protocols: XML-over-HTTP, REST, and SOAP. You will learn how to develop web services at all levels of complexity and for all kinds of business situations.

Approach:This book is an overview of how to implement SOA using Java with the help of real-world examples. It briefly introduces the theory behind SOA and all the case studies are described from scratch.

The book is out now and is available from Packt. For more information, please visit: http://www.packtpub.com/service-oriented-architecture-for-java-applications/book

Imagine having a magic pen that allows you to write what you desire and have it materialize before your eyes as you read it. Imagine what you’d write down with that pen knowing it will come true.

You can witness this phenomenon first hand, by using one of the most powerful techniques in the Law of Attraction repertoire–scripting.

Scripting incorporates the Law of Attraction so you can be, do and have everything you desire.  Scripting is one of the best kept secrets for accelerating what you want by using the Law of Attraction.

Scripting involves writing what you desire as if you’ve already obtained it and then reading it over and over again while watching it be attracted into your life. 

You might use scripting to lose weight, increase wealth, find love or for myriad other desires. You may also want to use it to become more outgoing, smarter or funnier or overcome any fears or anxieties. You may use scripting for how you want your day to go or a particular event to go.  

Scripting fuels your desires. It surrounds your desire with the positive energy to propel it into existence. Scripting allows you to see your desire with such clarity that it has you taking the appropriate action to actualize your desire via the most effective means.   

As you read on, you’ll be taken through the script writing process so you can have scripts that come true.   

Step 1: Define what you desire:

What do you desire? Whether you desire a new car, to find your true love, a raise or just to be happy, scripting will get you what you want. If you can write it, you can have it! 

Once you’ve identified your want or have identified what you don’t want and have spun that to its opposite, we’re ready for the next step. 

Step 2: Write your desire:

As you write it, picture it and feel it. Don’t think too much, just get it written down. Write your desire as if you’ve already obtained it. Your script should motivate and excite you. 

Step 3: Add feeling:

After writing what you desire, your script may look like a skeleton. Put some meat on those bones by adding supporting detail, including feelings to your script. Write out how you’d feel as if your desire has already manifested itself.  

To attract what you want, it’s important to feel good, so you can send a powerful signal and attract your desire. Every script should be worded in a way that’s going to make you feel good. 

Step 4: Add the Whys:

Ask yourself, “Why do I want this?” And include that in your script. When you consciously know why you desire something, you’ll be more apt to acquire it. 

Step 5: Add the Hows:

Imagine how you’d like to see yourself achieving the result. Then write as if you’ve already achieved your result and how you did it.

You might be specific in some areas, but in other areas you may be general and let the Universe decide how you will accomplish it. 

Step 6: Read it! Read it! Read it!

As you read your script, you’ll summon the powers from the Universe. You’ll be amazed as it comes true. 

Scripting can immediately increase your wealth, health and happiness. By utilizing this powerful technique, you’ll be able to watch your desires be transformed into reality– as if you used a magic pen.  

I realised that programming in Java is quite a fun only after doing it myself. You will be amazed to know that it’s like putting different pieces of puzzle together. You put them relatively in an integrated and coherent manner. The Beauty of it is, that most of the times you dont have to create these pieces yourself. You just customize them according to your need after you get them from an already defined java class or package. It was about programming, now lets talk sumthing about sockets.

Socket is used to establish a point-to-point, bidirectional connection between two entities in a network. Just like a real world socket, it is used to plugin a connection from another source. The connection can be incoming or outgoing or both. Similar is the case at the other end. To understand these sockets  properly, you need to learn a bit about Operating System and its Networking Protocols. Sockets are basically of three types: 1)UNIX Domain Sockets; 2) Internet Domain Sockets; 3) NS domain Sockets.

Java being platform independent Programming language, supports only Internet Domain Sockets as only they are platform independent out of three. These internet domain sockets are distinguished on the basis of Internet protocol they work on…

1) TCP/IP(Transfer Control Protocol): The data transfer is reliable, in-order,connection oriented, so takes connection establishment time before the actual data transfer takes place. Sockets based on TCP/IP are known as Stream Sockets.

2) UDP(User Datagram Protocol): It is connectionless,unrealiable and unordered data transfer protocol. Each packet in it has a destination address associated with it and is realeased into the network to make its own way. The sockets based on UDP are called Datagram Sockets.

3) Raw IP: It is a non-formatted protocol. Unlike TCP/IP, UDP protocols, Raw IP is not a core protocol of IP Suite. It’s different from them as its used to receive header information of the packet along with data, which is not the case in TCP/IP, UDP, they just receive data.

In Java Sockets are mainly implemented from already defined classes and pakages. These are:

1) Java.net.package: It contains all the classes that a user require to create a network based application. The below mentioned classes namely ServerSocket and Socket are also its part. This package also contain classes to create Secure Sockets and to connect a Web Server.

2) ServerSocket Class: It Provides sockets for the Server side.These sockets monitor network for requests or simply waits for them. When such request arrives, a server socket performs assigned task based on the request.

3) Socket Class: This class provides the Client side sockets. These sockets connect to the server, send and receive data for the client.

Remember, no socket can work without a port which is identified by a port no. Port is a gateway to a socket connectivity which is on the both sides of network. A socket is mainly identified as per its ports.
