Hibernate in Java – What Should Developers Know?

As the name suggests, Hibernate Object-Relational Mapping or ORM is an object-relational mapping library that is used in Java. The library provides a framework that helps in mapping object-oriented models of domains. The main objective of Hibernate is to solve the object-oriented impedance issues through the process of replacing the direct persistence-related accesses of database with functions that are involved in high-end object handling.

The primary feature that Hibernate comes up with is a unique mapping ability from various classes that are used in Java to the database tables and the same from Java data types to the SQL data types. The library also provides a string of retrieval facilities as well as a high end data query that facilitates handling the backend features. It also generates SQL calls, while making the lives of the developers easier, by automating set handling as well as object conversion. Besides, applications that use Hibernate also support SQL database with hardly any performance overhead.

What is the Future of Java Web Development?

As a concurrent and powerful programming language, Java enables developers to run their code on multiple platforms without recompilation. Java is currently reported to be used by over nine million developers to client-server web application development. While releasing Java 8 officially, Oracle called it as “the Most Significant Upgrade to the Java Programming Model Ever.” Oracle even delayed the release of the most anticipated version of the programming language to make it meet the ongoing and upcoming trends in web application development. The new features will definitely contribute towards increasing the increasing the popularity and market share of Java in the future.

Key Java 8 Features Web Developers were Looking for

Lambdas
Lambdas or closures are the most prominent feature of Java 8. The programmers can use lambdas to treat functionality as a method argument, treat code as data, and accomplish certain task by using concepts they are familiar with. Oracle has further designed lambdas after detailed discussion with the community of developers. Lambdas can be simply represented as a list of parameter separated using commas. However, developers have emerged the concept of functional interface by making existing functionality of the programming language lambda-friendly.

Extended Interface Declarations
The updates version of Java further uses default and static methods to extend the interface declarations. Despite making interfaces similar to traits, default method helps developers in accomplishing a different goal. They can use the method to add new methods to an existing interface without affecting the code’s binary compatibility with over versions of the interface. On the other hand, the abstract method can be user to accomplish these tasks without being implemented. As the default implementation needs to be provided by each interface, the implementers can inherit it by default.

StampedLocks
Often developers find it daunting to write multi-threaded code. They also have to use complex idioms to the core Java libraries to access the required resources by reducing the thread wait. Java 8 comes with StampedLock, a new and improved ReadWriteLock that works more quickly. However, the new ReadWriteLock is complex, and the programmers have to put some efforts to implement the concept properly.

Process Termination
When a web application has to launch an external process, its performance will be affected hugely when the process hangs, crashes or consumes 100% CPU. The developers have to debug the web application again to make it run smoothly. But Java 8 comes with the Process class that allows developers to manage these unruly processes smoothly by using the isAlive() and destroyForcibly() methods. The isAlive() method can be used to check if the external process is still alive, whereas the destroyForcibly() method will kill the timed-out process forcibly.

Controlling OS Processes
The JNI calls make it easier for developers to launch OS process from within the code. But there are always chances that the OS process may fetch unexpected results or affect the functionality of the internet application. Once a process is launched within the Java code, it tends to dangle. Java 8 enables developers to control the OS processes launched within the code efficiently by using three new methods. Along with checking if the process is alive and killing a process forcibly, the programmers can further use the method to specific amount of time they want the web application to wait for the process to be completed.

Repeating Annotations
Java 8 allows programmers to use annotation in any context. Now they have option to use annotations for almost everything in their code including generic types, local variables, super classes, interface implementation, parameter declaration, and declaration of method’s exceptions. The extended usage of annotation makes Java 8 friendlier for instrumentation tools and static analysis. However, the programmers have to decide when to use annotations according to the nature and needs of the code.

There are also a number of features that make Java 8 a powerful programming language for web application development. Some of these Java 8 features will further make it easier for developers to build large and complex internet applications within a stipulated time frame.

Why is Java preferred over .Net by enterprises?

The question of whether to prefer Java (J) over .Net has been disturbing the fraternity of developers for quite some time. While some say that it is better to vouch for .Net rather than opting for ‘J’, another school of thought says that it is preferable to use ‘J’ instead of opting for .Net. Let us discuss the reasons for which the enterprises nowadays like to prefer Java over .Net.

Open Source
The fact that Java is an open source language clearly implies that users will not need to pay any licensing fees to Oracle for developing any software using ‘J’. The language is easy, quick to learn and most importantly, complete with a number of value added features and functionality that meet today’s needs. On the other hand, the development of .Net is pretty time consuming as it is far more complicated than ‘J’. Moreover, .Net makes you shell out a substantial amount of money, albeit the presence of a string of free tools. Most importantly, .Net is often plagued by the presence of a number of features with limited functionality.

The advantage that the companies enjoy while using ‘J’ is that they are able to slash the cost of development by a considerable amount with the use of a specific framework for open source software development. Naturally, for the enterprises that are running on a shoestring budget ‘J’ is the best option to vouch for. Besides, since ‘J’ is an open source platform, it helps the developers in doing whatever they feel like and create software solutions as per their will, with the support of a number of development tools that are supported by ‘J’.

Java is platform independent
When it comes to developing cross platform software, ‘J’ is absolutely indomitable. The software systems programmed with the help of ‘J’ codes are executable and can be run across multiple platforms. This is because JVM implementations are cross platform and are compatible with all the major platforms.

When it comes to software development using .NET, Mono can be used for building applications that are compatible to all the major OS. However, what is missing in .NET that ‘J’ comes up with is the user-friendly approach. This is where ‘J’ scores over .NET. Frankly speaking, Java is indeed an ideal platform for software development that makes the entire development process much simpler as well as less cumbersome.

Active Community
The most important part if Java is that, the solutions are absolutely free of cost compared to Microsoft, which charges a hefty amount of money for each and every solution. Java, on the other hand regularly keeps on updating itself with new features, besides improving its functionality as well as effectiveness that comes in handy while creating Java platform. This implies that every software as well as applications can enjoy the advantage of the very latest state of the art technology, without any extra expenses whatsoever – a reason that is enough for the huge popularity of Java.

Safety and Security
Java is more popular because of the improved version of safety as well as security than any other programming language including .Net. Java comes up with certain features that include automatic null checking, verification of each and every byte before execution, run time checking of security along with a string of similar kind of features, which help the developers in building secured apps.

Besides all these, Java helps to infuse a tinge of intelligence in every aspect of our life by changing things that are around us or things that are indispensable parts of our modern life like various electrical or electronic devices, homes, appliances, cities, automobiles and other items that we use in our day to day life.

There are surely other programming languages that are quite useful and are regularly used, but when it comes to discussing about any matured software programming language, nothing can be as handy and as useful as ‘J’ and this is the reason enough that the language is more acceptable and adorable than any other programming language including .Net by the modern enterprises.

Some of the biggest myths about Java

Java’s first version was launched in 1995 and since then several versions have been launched after fixing bugs as well as making improvements. Despite, being in the industry for such a long time, there are a lot of myths associated with Java since there are many people who will believe exactly what they want to believe, ignoring all better judgement. There have been much speculations, discussions as well as arguments related to various aspects of Java. This article aims to bust a few common myths that are associated with this language in the minds of people.

java web application development

It is slow- A few people feel that this is slow in the start-up times, especially when compared with C++ or simple PHP applications. The applications may take some time for loading but the same can be said for .NET or other such big libraries. However, the latest Java update ensures that the loading time is much faster in comparison to the previous models. There is no point in comparing it to other programs as each has its own individual set of problems associated. C++ is the fastest but Java can be said to be faster than many other languages.

It is dead- This is said by a few since it has been in the industry for almost two decades and its last major release had been quite some time back. However, it is not fair to assume that it is dead just because of that since similar instances of no major releases can be found in C++ or Microsoft Windows. Other languages may evolve quite fast but you must remember that these languages are quite new, so they need much polishing to be done. Some people also cite that the language’s popularity is slipping through some indexes or statistics. But if investigated properly then it may be seen that these surveys are actually incomplete. They do not show the full truth, just investigate a few parameters.

Your hard drive may be read and files deleted by applets- The truth is that when applets attempt to access any local file, then a SecurityException will be thrown. The applets will crash if it is uncaught but without any file access occurring. Digitally signed applets that are granted with additional privileges, is the sole exception to this. A dialog box will be displayed by your browser to ask whether the applet author’s identity is accepted or not. If unsure it is best to choose no, to be safe.

Applets cannot be relied upon as differences in Internet Explorer and Netscape does not make writing stable applets a stable proposition- Different JVMs, various versions and kinds of browsers result in the varying behaviours of running applets. The users as well as developers may find the differences frustrating but the best solution for this is using single JVM to use across all browsers. This can be achieved by virtue of Java Plug-in which can bypass the JVM of browser to use its own, resulting in uniform performance.

Web browser is a must-have as Java cannot run without it- There are several forms of the code. Users are mostly familiar with applet running inside web browsers. But it is very simple to run Java application like normal programs. All you have to do is install JVM from some vendor to run the programs. A web server often runs Java servlets which may be termed as replacements for ASP or Active Server Pages as well CGI scripts. These are quite fast in fact and more efficient that CGI scripts.

Many people do not realize it, but there is a lot of potential in the language. There is more to the software than just applets. They are quite secure and hard drive will not be deleted. In case of any problem, installing plug-ins will help you solve them.

Is Java Most Suitable for Enterprise Applications Development?

The Java programming application has become the most preferred choice for large-scale, steady business schemes and is becoming more and more popular in embedded systems for portable computing devices. With the arrival of faster processors as well as not so costly mass storage devices, Java is allowed to transcend the original limitations of the language, and this independent environment makes it suitable for developing global enterprise applications and web services. Moreover, many portable devices and smaller systems can benefit from apps written in this programming language.

Java as Dead-End Enterprise Application Process

java web developmentIn earlier days when Java was yet to be invented, one of the major industrial trends was to raise the productivity of end users as well as developers. For instance, to develop business applications, fourth-generation programming languages (4GL) like Progress, Uniface or Powerbuilder rendered professional developers various quicker means than using C, C++, COBOL or Pascal. Tools like Lotus Notes, Dbase or Visicalc provided end users with the unparalleled ability to create mini-applications without any requirement for development teams. In the early ’90s, such productivity trend was thrown into a tizzy by the web. Now, enterprise application developers as well as software vendors need to write an entirely new generation of apps for the internet. This way the 4GL along with Internet forced developer productivity had to take the back seat.

For Web Apps Java Was at The Right Place at The Correct Time

To develop embedded systems, Java was designed in 1990 as an easier choice than C++. In 1993, the invention of the WWW initiated a meteoric change in Information Technology application development platform. Leading companies moved further and took advantage by marketing “network” servers like hotcakes and thereby offering Java as the platform for Web application development. Many other software vendors were caught off guard and for enterprise app development Java became the de facto web development standard.

Moving Ahead to Escape Drawbacks of Java Development Platform

This application has served its purpose and now it is time to go further as for enterprise-level app development, it seems to be too tricky or complicated. There are certain factors as to why business application development professionals must plan their escape from Java:

  • With sophisticated business scenario as well as requirements the pace of change has increased.
  • Development authoring is restricted to programming languages. Even though this platform supports additional programming languages such as Jruby or Groovy, the fundamental platform limits innovation to the conventional services offered by Java. Many new programming languages can be invented, but all of them should be applicable in the underlying environment.
  • This platform botched the presentation layer as JavaFX is a failure while Swing is a nightmare. For pre-Ajax user interfaces, JSF was designed in spite of some implementations viz. ICEfaces incorporate Ajax. In the presentation layer, new UI approaches are found to have a steady stream that reflect Java’s lack of leadership.
  • The Java frameworks show complexity. Struts, Spring, Hibernate and other environments reveal deficiencies of this programming language rather than its strengths. Simply to do the basics, a future platform must not need a cacophony of the same approaches.

As One of The Most Significant Programming Languages

So far as enterprise apps development is concerned, there is no denying that Java plays a major role despite tons of rise and falls. For the programmers, it brings a number of benefits including scalability, ample flexibility, security, robustness and of course versatility within the application development frameworks. However, like any other application platform, Java too has certain limitations that can be easily retrievable using faster processors and less expensive mass storage devices.

With this programming language, you can invent almost any form of enterprise-level application. In today’s world, many developers prefer using Java to build unprecedented business solutions by leveraging the features and benefits of this fantastic application platform.
