Hibernate in Java and Its Features

As an open source persistence library, Hibernate Object Relational Mapping (ORM) is used widely by Java developers. The framework provided by Hibernate makes it easier for Java developers to map an object-oriented domain model to a traditional relational database. Thus, Hibernate in Java uses direct persistence-related database access to resolve problems related to object-relational impedance mismatch. Continue reading Hibernate in Java and Its Features

Struts – In What Ways Does It Support Java Programming

Apache Software Foundation (ASF) has developers Struts as an open source web application development. The framework is being used widely by programmers to create Java EE internet applications. It enables web developers to create application by using model-view-controller (MVC) architecture by adopting and extending the Java Servlet API. The Java programmers also have option to use WebWork, a framework spun from Struts. Despite retaining the original architecture of Struts, WebWork comes with several enhancements and refinements. Thus, the Java programmers can rely on Struts to create large and complex enterprise application by Continue reading Struts – In What Ways Does It Support Java Programming

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 to expect from iOS 8 release?

The new products of Apple are generally released around the fall; thus those who are fans of their products wait with bated breath for the next releases around this time. In this context, the next releases from the Apple stable are supposed to be iOS 8 and iPhone 6 which will be released sometime around September. The news about iOS 8 release was publicized on June. Now, with just a few days left for the release, people are growing increasingly curious about the new additions or changes that might be introduced in it. Here is a sneak peek at some of the features which are expected to be seen in the new release.

In the previous 7th version, the operating system had seen vast changes in the design aspect; there was a total overhauling. So as per some reports, there will not be major changes in the design aspect. The focus would rather be on incorporation of new apps as well as features in this version.

Java Strings – Few things that Java Programmer Should Know

A Java class that is very widely used is known as string. It is considered quite special since compared to a normal class it contains some unique, special characteristics. It consists of some characters in a sequence; through the class the object can be created. There are many concepts which can be carried on through this and are worth knowing by most Java programmers.

Creation of objects or instantiation- The object can be created in two different ways- through new keywords and through string literal. Through double quote a string literal can be created. With its creation each time, the constant pool is checked by JVM first. If the pool already has the string then it returns the pooled instance’s reference. If the pool does not contain it then a new object is instantiated which is then placed there. Memory efficiency is increased by this. Through keywords, the object is created in a straight-forward manner by JVM.

Java for E-Commerce business – Is it good?

The computing platform, Java is independent, secure as well as robust, ensuring high performance. This network savvy, portable as well as architecturally neutral language uses automatic memory management. The programming language can be used to develop ecommerce applications easily due to the several feature sets that make it an effective ecommerce platform. It is platform-independent, network-aware, multi-threaded as well as object-oriented which make it really flexible. Near about any platform can be used for its running. Some of the reasons that have made it suitable for ecommerce business are discussed here.

Java 2 Enterprise Edition- Also known as J2EE, it has proved to be a revolutionary influence in the arena of e-commerce. Strong server side application can be build through the robust and solid solution of J2EE. The technology is fully-able and is extremely beneficial as a development tool. Some of the tools included in it that helps in this respect are Servlets, JSPs or Java Server Pages, Enterprise JavaBeans or EJB, JNDI or Java Naming and Directory Interface, JDBC or Java Database Connectivity, JTA, JMS along with Java Mail.

No programmatic configuration of navigation- To set navigation, a specified pattern has to be implemented which can be really complicated as well as a time-consuming process. But when you are using JSF, all the complicated procedures can be avoided altogether. The framework handles the navigation entirely. All that is needed is to associate page views, URL patterns as well as logical outcomes together by using Faces configuration file. Developers can also follow another method- using the implicit navigation feature of JSF 2.0 that forwards requests automatically to a view having the same name as that of the requested URL pattern.

Good templating support- The Facelets technology can be used for templating and it helps maximize markup reuse so that redundancy in page views can be reduced. It also allows the preparation of views through standard XHTML syntax. It allows easy creation of template layout which is common for all page views. In fact the views can be rendered with the insertion of content that is view-specific in the template.

Neutral platform- Several kinds of communications are required in ecommerce and there is a lot of data that changes hands. For the interaction of so many various kinds of systems and platform, you need a neutral standard platform that helps in this data exchange. This requirement can be filled up with XML or eXtensible Markup Language. It is quite crucial; the role of Java here is that it provides a great support to XML which combines well with this programming language.

Validation support is in-built- Server side validation support is provided by JSF. All validation can be performed by creation of validator class as well as logic that is manually coded. The server-side validation will occur automatically by virtue of JSF at the particular phase.

View rendered with several markup languages- The API technology boasts of flexible rendering that enables the attaching of several renderers to component tree of an application that is JSF-enabled. Thus custom components can be created.

Server support- Java is supported by several application servers like IBM WebSphere, BEA WebLogic, etc which are full of different types of features. Now, any one of them can be easily chosen due to the support extended.

Labour division well-defined- A huge advantage of this technology is that there is a clean separation between presentation and behaviour of web apps. This is especially great for large projects since it provides separate development areas where various team members can focus differently.

Ecommerce developers prefer Java over any other platform since it offers a number of benefits in areas such as security, ease of use, portability, flexibility and accessibility. It is present at both server as well as client sides and coupled with its efficacy this makes for an unmatched killer combination.
