Java is widely and high competitive words on Google or any other search engine. Today for online business application, java is the best option. When you find the sentence like we offer java solutions then you confuse obsessively why not. Java solutions mean use java and its latest technologies for web development, software development, Enterprise management software development, and mobile application development. However, you have one questions how all above development is possible through java. Not worry its can developed using latest java technology tools and frameworks like eclipse, struts, J2ME, J2EE, J2SE, JDBC etc.

Java is widely used for web application development like e-commerce application, online shopping cart, dynamic website, blog etc. Web application using java is more secure, reliable, and robust then PHP and.net solutions. Today many big business owners or company would like to make their e-commerce web application through they sell their products or services across the world. However, security is main point for any e-commerce application because if you have popular then its chance to theft your transaction, important details for customer, products etc. So as per my way java is the best option for e-commerce application.

Many outsource software development company offers java solutions e-commerce applications. They use latest frameworks or tools for e-commerce applications. Here I am listed downside some of the famous java e-commerce platforms with its creative features and benefits.

The recession is almost over; a state has reached where one can even ask ‘When did the recession thing actually happen?’ The end of the recessional year was marked by an increase in the number of recruitments done by IT companies. A company which used to take 100 to 200 students across campuses, after recession are aiming to take the figure to a three digit mark.

When IT companies are hiring to such an extent and the fact that no IT company would take a candidate who lacks basic intelligence, it is but an obvious fact that the candidates would still face some kind of a screening procedure. If one goes by the latest trend, the screening procedure comprises of 3 stages; a written round, a technical interview & a HR interview. Some companies also conduct a GD before the interview and club the technical and HR interview together.

One, who lacks good communication skill, can still manage to have an edge over other candidates if he/she can show some impressive skills during the technical interview. Even the individuals with decent communication skills need to put up a good show in front of the interviewer. If you are able to convince the interviewer that you are the best man for the job, then he may neglect your other weaknesses and you would smoothly slide through. Now, when we study and analyze a technical interview, we find that instead of going for complex logics and heavy codes the company’s focus lies dominantly on the candidate’s basic knowledge. You would not be asked to write the code for a finger print scanner, or how to prevent a hack to a RBI website. What you would be asked would be the very basics of a particular technology or a standard well accepted working platform, something like java.

Java, in a very short span of time, because of its attributes has become the dominant working platform in almost every IT company. So a lot of technical interviews are centered on Java, and a lot of interviewers end up asking questions relating to java basics. A java technical interview can be divided in two parts. Core java interview questions and advanced java interview questions. The trend is to move to the advanced java interview questions only when one performs well during the core java interview questions session. The core java interview question comprises of questions like.

1. Can a class be declared protected?

2. Can inner class be a final class?

The questions can either be either focused on java keywords or on the java code structure.

Questions involving of code snippets like,
public class Test {
final int i;
public Test(){
i=10;
setup();
}
public void setup(){
// setup code
}
}

Will the above code will run?

are put up to know whether the candidate is familiar with the java working environment, and whether he/she know in what order a source code gets executed. If you fair well during the core java interview questions, then the interviewer might move on the advance java interview questions like j2ee interview questions, java script interview questions, servlet questions, JSF questions etc. However that depends on the organization’s recruitment procedure, but one should be prepared to face anything and everything. After all only the interviewer can question you and not the other way around.

This is the reason for developing a Java Content Management System. Java CMS offers lesser effort of coding while enjoying the benefits of sophisticated results. Through the efforts of online communities and developers, they were able to come up with Java CMSs that will suite each user’s requirements and demands. Furthermore, what makes it more interesting was, most of them are free and open source as well.

Top Java CMS

1. Apache Lenya – It comes with revision control, WYSIWYG editors, workflow and multi-site management, scheduling and internal search. It offers a wide set of asset management which allows you to keep track of images and documents that is, you could still retrieve deleted pages from the trash. Each parts of your site are covered by Secure Sockets Layer (SSL), which protects the security of message transmission over the internet. Convenience plus security, that was just great!

2. Magnolia – this is the first open source content management system that was developed to support upcoming standard API for java content repositories. It is widely known for its simplicity and ease of use. Magnolia offers features which made editing and publishing content fast and at ease. A highly customizable advantage which give you the opportunity to design your own site the way you want it. Supports standard API for Java Content Repositories (JCR).

3. Blandware Atleap – offers a comprehensive full-text search engine. It is designed to create content-based sites and web applications through complex business logic. Supports multilingual capabilities which can store content on several languages at the same time using UTF-8 encoding. It also supports indexing document formats like: Word, Excel, PowerPoint, RTF, PDF, ODF, HTML, XHTML, XML, and TXT. Another thing that makes Blandware Atleap more interesting is its quality of individualization. It doesn’t restrict creative graphical design of the site.

4. Contelligent – it is a kind of a java based CMS that is commonly used for the creation and management of personalized websites. It allows the re-usage of existing content and layout in some contexts for new and/or unplanned needs. It also supports dynamic customization based on users, roles and preferences and has a high level of performance caching and dynamic page rendering.

5. Daisy – it has a standalone repository server that is widely accessible through HTTP, XML or high-level Java API. It also supports a comprehensive browsing and editing application (DaisyWiki) that is running inside Apache. Moreover, it also contains a XSLT-based templating system that offers ultimate free will of customization and flexibility.

Those were just few of the many effective and efficient Java CMSs available over distributors and even on the web. Above ranking was based on my personal view as an IT professional. Some of those may not be included on your list or my ranking maybe far different from yours. But what is important was, you have to choose a CMS that will suite your need either as an individual, professional, enterprise or company.

Java is a very popular programming language which involves various syn-taxes from C++ and C language. But it has a simpler model then these two other complex programming languages. It has object model and low-level facilities for the users which makes it easier and simpler to use and understand.

Java Application Programming was developed by a person named James Gosling in 1995, at a present date subsidiary of Oracle Corporations, which was then called as sun Micro-systems. JVM or Java Virtual Machines are needed to run these java applications which are compiled to class file format. Irrespective of the computer architecture JVM is always required to run this type of files. Java Application Programming is specifically designed to have the least amount of implementation bottlenecks. It works on the principle of “write once, run anywhere” pattern.

It means once your write the coding of the program, you can use it on other destination too. You don’t need to write it again and gain every time. Java is not only a programming language but also a software platform, which lets the application developers to use this simpler, class based and object-oriented programming language instead of the complicated high level languages like C and C++.

But the major disadvantage of using Java Application Programming is that, the programs written in Java are slower and need more memory space to get stored then the programs written in C language.

For that concern, the sun Micro-systems have been working upon java technologies under the specifications of the Java community process. And have achieved remarkable success in the context of introducing Just in time compilation model to run these applications in the year 1997-98. Some new language features have been added to the language like inner classes, optional assertions and String-buffer class etc.

Java has compilers in it, which conduct the basic functions whenever an application developer writes a code with syn-taxes and characters to run a particular Java Application Programming code.

For faster speed a company names Systronix has developed a micro-controller called jStik based on a line of java processors. A standard edition for Java Application Programming language has various components. It uses multi-tier architecture for database connectivity. It uses XMl files to store data and writing codes. JDOM is used for outputting XML data from Java code.

All the components of java work together to perform a given task, and such components are listed below:

1. Development tools and APIs as Java complier, Java debugger, Javadoc and JPDA
2. Deployment technologies could have sub-parts like Java web-start and Java plug-in
3. User interface tool kits are swing, AWT, sound, input methods, java 2D and accessibility.
4. Integration APIs are RMI, JDBC, JNDI, and CORBA.
5. Core APIs are like XML, logging, beans, Locale support, Preferences, Collections, JNI, Security, Lang, Util, New I/O and Networking
6. Java virtual machines are of three types as, Java hotspot client compiler, Java hotspot server complier ad Java hotspot VM runtime.

The various Java platforms are:
• Solaris
• Linux
• Windows
• And others.

Java is a complex object-oriented computer programming language which is a result of some concepts taken from other computer languages such as C and C++. Although there are abound negative feedbacks, Java is generally considered to be the most admired multi-facets computing language that is utilized in today’s generation.

There are quite a number of reasons why Java is on the top spot when it comes to computer language. First off is the fact that composite dynamic website processes are achievable in Java programming. With Java being a multithreaded language, its use in superb and fast applications is increasing. An evidence of this is its presence in most gadget applications up to the fastest computers found today. As Java applets are platform-independent, the program can straightforwardly be accessed by a software developer and it can be run in various platforms. One of Java’s best features is the truth that even it is a very powerful and vigorous, this programming languages comes out free. It is an open source programming language which has a mechanical garbage collection. With regards to the database, Java can adapt to any database may it be paid or free. And the last but not the least is the reality that Java language is a collection of well planned and APIs which aids Java coders to do improved outputs without any annoyance.

The IT world has a number of platforms nowadays. This gift of numerous choices provides advantage and disadvantages. On one hand it provide more options to the developers or consumers; on the other hand making a software that is working on all platforms is becoming very scarce. To address this concern, there is now Java Platform which is intended for running extremely interactive, lively, and safe applets and computer applications on a set of connections of different computers.

Software developers can make applications on a single platform to deliver to that same platform — the Java Platform, which is accessible on a wide array of operating systems. This greatly minimizes the developing cost of the software. For support workforce, version management and advancement are much easier for the reason that Java-enabled software application can be found in a central storage area and work from that location for each individual handling.

The bottom line is, if you wish to study Java and become a professional on this field, you will certainly be ahead of the game. To start off, since Java is a popular language, you can turn on to basic Java tutorials found online or find a Java book with positive reviews. Deciding to be in this field is an action you shall never regret.

Offshore software development helps to obtain the services of an external supplier positioned geographically apart from the client. The main reason of usage of this service is the high development costs borne by the hiring local services. India is the world leader in outsourced project development, be it the information technology or business process outsourcing. The companies offering services does a feasibility study of the project, after determining that the project is feasible, gathers the software requirements after consulting the customer and the managerial level, which is carried out through a series of interviews. The requirements are then documented and presented to the project members for creating the project design. According to the project design, the coding phase is carried out followed by the testing and debugging phase. Finally after the implementation of the software, the maintenance is carried out as and when required.

If you are a beginner when it comes to the Java programming language or even if you are an experienced programmer looking for some new tips&tricks, the best thing to do, and which has the advantage of being absolutely free of charge, is to search the Internet for Java tips and Java tutorials.

Try this instead of buying one or two books, and you are going to be impressed by the quantity of information you’ll find available about the domain. This is the easiest way to access tons of Java tutorials or a lot of very useful Java tips with no effort and no cost at all.

The Java programming language and platform were first developed during the early nineties and a few years later it was re-designed for use in the Internet, and since then its popularity greatly increased, especially on the server side of the Internet.

Nowadays there are quite a lot of Java experts and a lot of documentation on this subject has been written, so if you are a beginner start searching for Java tutorials to learn more, and if you are an advanced user, you can always make use of the large number of Java tips that can be found and that can help you solve almost every problem you encounter in your path to making perfect Java programs.

Even for those who are ablsolute beginners in learning about Java, better and easier than attending courses is learning from the Internet Java tutorials. They can find anything from getting started, the basics of the Java language, essential classes, to more specialized tutorials like security in Java, graphics, working with databases and many more things. You can find websites that are specialized in giving Java tips and Java tutorials to those who need. Those tutorials and tips are written by experts and are placed in categories, which helps you immediately find the Java tips or the Java tutorials that you are looking for. The best thing when learning is to read more Java tutorials, and to combine the Java tutorials you learn from with the short and useful Java tips you find.

On the other side, if you are an experienced programmer and you want to share your knowledge, you can begin writing Java tutorials and Java tips to help the newbies and other who need it.

When writing Java tutorials make sure you make yourself clear and understood and that you are covering all the aspects of the problem.
Also, when writing Java tips, if you want people to easily find and understand the information you are delivering there are some ‘rules’ you should respect, like choosing the best title of the Java tip, that captures exactly what you are presenting, and the best subtitle of course, which must expand the title a little, you can also add a short summary or comment if you wish where you describe what your Java tips do, then proceed with the introduction, the code listing, the explanations for it and also a little conclusion if you desire. You can even include a link to more detailed Java tutorials on that subject also.

Java is an object oriented and structured programming language, designed by Sun Microsystems in the year 1991. Java is a third generation programming language. It has an in built application interface which has the ability to handle the graphics and user interfaces that creates the applets or applications.

The very advantage of java is its “portability”, the programmer can write the program and compile in the same kind of environment as it is written and after that it can be run anywhere.

Java relates to both C and C++, it uses the syntax of C and the object oriented concepts from c++ and this makes Java appealing. When a source code is given as the input, the output from java compiler is the “bytecode”. Bytecode contains set of instructions which will be executed by Java Virtual machine (JVM). In a more simple way, I can say JVM interprets the bytecode and this is the reason that java can be run anywhere. Applets are the programs which are embedded in to web page and can be executed where as the applications are directly executed by JVM.

It is not always possible to compile the complete program at the same time, so java uses just-in-time compiler to compile a set of bytecodes in real time for execution and the remaining codes will just be interpreted and thus makes the execution of Java program faster. The two main building blocks of java programming are the classes and objects. Objects are the instance of class and class is a template for creating objects.

Unlike in c/c++ you need not manually allocate/de allocate dynamic memory, java itself does this and also it has garbage collection for the unused objects. Java program handles the run time errors too. Java supports multithreaded programming.

Decouple validation processes from your business object implementations

Version 1.3 of the Java platform saw the introduction of the dynamic proxy facility. Dynamic proxies offer many interesting solutions to Java developers, including a validation scheme that easily decouples validation logic from an application’s core business logic. In this article, Java developer Eric Olson shows you how dynamic proxies can keep your core application code free of validation routines and focused solely on business logic.

Validation is an essential aspect of many enterprise applications. Most business methods contain validation logic to ensure that pre-conditions are met before carrying out business logic. Code that deals with values entered through a user interface employs validation logic to ensure that the values entered by a user are valid before carrying out actions that may affect other areas of the application or other users. Validation is an especially important component of applications that employ and interact with other loosely coupled components, as well as services that may not be strict in their assertions.

As important as it is to the safety and functionality of your business applications, core application logic is often cluttered with validation routines. Validation processes are often scattered throughout method calls, making it difficult to tell the difference between validation logic and core business logic. In most cases, business objects and methods must know some details of the validation process and deal with them directly in their implementation — for example, a business object may throw a validation exception directly from the business method (either coded directly in the method, or as a result of calling some validation service). The validation exception in this case is really a byproduct of the validation process, however, and would ideally be hidden from the business object implementation.

In this article, I’ll show you a more decoupled and centralized approach to validation, using the dynamic proxy facility introduced to the Java platform with version 1.3. Working with a single example throughout the article, I’ll demonstrate the weaknesses of both tightly coupled and loosely coupled validation schemes, and then show you how dynamic

The Java API for XML Processing (JAXP) lets you validate, parse, and transform XML using several different APIs. JAXP provides both ease of use and vendor neutrality. This article, the first of a two-part series introducing JAXP, shows you how to take advantage of the API’s parsing and validation features. Part 2 will cover XSL transformations using JAXP.Java technology and XML are arguably the most important programming developments of the last five years. As a result, APIs for working with XML in the Java language have proliferated. The two most popular — the Document Object Model (DOM) and the Simple API for XML (SAX) — have generated a tremendous amount of interest, and JDOM and data-binding APIs have followed (see Resources). Understanding even one or two of these APIs thoroughly is quite a task; using all of them correctly makes you a guru. However, more and more Java developers are finding that they no longer need extensive knowledge of SAX and DOM — thanks largely to Sun Microsystems’ JAXP toolkit. The Java API for XML Processing (JAXP) makes XML manageable for even beginning Java programmers while still providing plenty of heft for advanced developers. That said, even advanced developers who use JAXP often have misconceptions about the very API they depend on.

This article assumes that you have some basic knowledge of SAX and DOM. If you’re new to XML parsing, you might want to read up on SAX and DOM first through online sources or skim through my book (see Resources). You don’t need to be fluent in callbacks or DOM Nodes, but you should at least understand that SAX and DOM are parsing APIs. It would also help to have a basic understanding of their differences. This article will make a lot more sense once you’ve picked up these basics.
