Oracle and Sun Microsystems Strategic Acquisitions. Oracle acquired Sun Microsystems in 2. Oracles hardware and software engineers have worked side by side to build fully integrated systems and optimized solutions designed to achieve performance levels that are unmatched in the industry. Early examples include the Oracle Exadata Database Machine X2 8, and the first Oracle Exalogic Elastic Cloud, both introduced in late 2. During 2. 01. 1, Oracle introduced the SPARC Super.

Cluster T4 4, a general purpose, engineered system with Oracle Solaris that delivered record breaking performance on a series of enterprise benchmarks. Oracles SPARC based systems are some of the most scalable, reliable, and secure products available today. Suns prized software portfolio has continued to develop as well, with new releases of Oracle Solaris, My. SQL, and the recent introduction of Java 7. Oracle invests in innovation by designing hardware and software systems that are engineered to work together. Spring Framework Wikipedia. The Spring Framework is an application framework and inversion of controlcontainer for the Java platform. The frameworks core features can be used by any Java application, but there are extensions for building web applications on top of the Java EE Enterprise Edition platform. Although the framework does not impose any specific programming model, it has become popular in the Java community as an addition to, or even replacement for the Enterprise Java. Beans EJB model. The Spring Framework is open source. Version historyeditThe first version was written by Rod Johnson, who released the framework with the publication of his book Expert One on One J2. EE Design and Development in October 2. The framework was first released under the Apache 2. June 2. 00. 3. The first milestone release, 1.

Spring 5 is announced to be built upon Reactive Streams compatible Reactor Core. ModuleseditThe Spring Framework includes several modules that provide a range of services Inversion of control container dependency injectioneditCentral to the Spring Framework is its inversion of control Io. C container, which provides a consistent means of configuring and managing Java objects using reflection. The container is responsible for managing object lifecycles of specific objects creating these objects, calling their initialization methods, and configuring these objects by wiring them together. Objects created by the container are also called managed objects or beans. The container can be configured by loading XML Extensible Markup Language files or detecting specific Java annotations on configuration classes. These data sources contain the bean definitions that provide the information required to create the beans. Objects can be obtained by means of either dependency lookup or dependency injection. Dependency lookup is a pattern where a caller asks the container object for an object with a specific name or of a specific type. Dependency injection is a pattern where the container passes objects by name to other objects, via either constructors, properties, or factory methods. In many cases one need not use the container when using other parts of the Spring Framework, although using it will likely make an application easier to configure and customize. The Spring container provides a consistent mechanism to configure applications and integrates with almost all Java environments, from small scale applications to large enterprise applications. The container can be turned into a partially compliant EJB Enterprise Java. Beans 3. 0 container by means of the Pitchfork project. Somewho criticize the Spring Framework for not complying with standards. However, Spring. Source doesnt see EJB 3 compliance as a major goal, and claims that the Spring Framework and the container allow for more powerful programming models. You do not create an object, but describe how they should be created, by defining it in the Spring configuration file. You do not call services and components, but tell which services and components must be called, by defining them in the Spring configuration files. This makes the code easy to maintain and easier to test through Io. C. Aspect oriented programming frameworkeditThe Spring Framework has its own Aspect oriented programming AOP framework that modularizes cross cutting concerns in aspects. The motivation for creating a separate AOP framework comes from the belief that it should be possible to provide basic AOP features without too much complexity in either design, implementation, or configuration. The Spring AOP framework also takes full advantage of the Spring container. The Spring AOP framework is proxy pattern based, and is configured at run time. This removes the need for a compilation step or load time weaving. On the other hand, interception only allows for public method execution on existing objects at a join point. Compared to the Aspect. J framework, Spring AOP is less powerful, but also less complicated. Spring 1. 2 includes support to configure Aspect. J aspects in the container. Spring 2. 0 added more integration with Aspect. J for example, the pointcut language is reused and can be mixed with Spring AOP based aspects. Docx To Pdf Converter Plugin For Office 2007. Further, Spring 2. Spring Aspects library that uses Aspect. J to offer common Spring features such as declarative transaction management and dependency injection via Aspect. J compile time or load time weaving. Spring. Source also uses Aspect. J AOP in other Spring projects such as Spring Roo and Spring Insight, with Spring Security also offering an Aspect. J based aspect library. Spring AOP has been designed to make it able to work with cross cutting concerns inside the Spring Framework. Any object which is created and configured by the container can be enriched using Spring AOP. The Spring Framework uses Spring AOP internally for transaction management, security, remote access, and JMX. Since version 2. 0 of the framework, Spring provides two approaches to the AOP configuration schema based approach1. Aspect. J based annotation style. XMLSchema instance. Locationhttp www. The Spring team decided not to introduce new AOP related terminology therefore, in the Spring reference documentation and API, terms such as aspect, join point, advice, pointcut, introduction, target object advised object, AOP proxy, and weaving all have the same meanings as in most other AOP frameworks particularly Aspect. J. Data access frameworkeditSprings data access framework addresses common difficulties developers face when working with databases in applications. Support is provided for all popular data access frameworks in Java JDBC, i. BatisMy. Batis, Hibernate, Java Data Objects JDO, Java Persistence API JPA, Oracle Top. Link, Apache OJB, and Apache Cayenne, among others. For all of these supported frameworks, Spring provides these features. Resource management automatically acquiring and releasing database resources. Exception handling translating data access related exception to a Spring data access hierarchy. Transaction participation transparent participation in ongoing transactions. Resource unwrapping retrieving database objects from connection pool wrappers. Abstraction for binary large object BLOB and character large object CLOB handling. All these features become available when using template classes provided by Spring for each supported framework. Critics have said these template classes are intrusive and offer no advantage over using for example the Hibernate API directly. In response, the Spring developers have made it possible to use the Hibernate and JPA APIs directly.
