Since the first version of this article was published in October, 2. Spring Framework has steadily grown in popularity. It has progressed through version 1. In this article, Ill try to explain what Spring sets out to achieve, and how I believe it can help you to develop J2. EE applications. Yet another framework You may be thinking not another framework. Why should you read this article, or download the Spring Framework if you havent already, when there are so many J2. Service Support Tool Canon. EE frameworks, or when you could build your own framework The sustained high level of interest in the community is one indication that Spring must offer something valuable there are also numerous technical reasons. AnnotationBasicTree.jpg' alt='Spring Framework 3.0 Jar Files' title='Spring Framework 3.0 Jar Files' />I believe that Spring is unique, for several reasons It addresses important areas that many other popular frameworks dont. Spring focuses around providing a way to manage your business objects. Spring is both comprehensive and modular. Spring has a layered architecture, meaning that you can choose to use just about any part of it in isolation, yet its architecture is internally consistent. So you get maximum value from your learning curve. You might choose to use Spring only to simplify use of JDBC, for example, or you might choose to use Spring to manage all your business objects.

Spring is designed from the ground up to help you write code thats easy to test. Spring is an ideal framework for test driven projects.

Spring is not necessarily one more framework dependency for your project. Spring is potentially a one stop shop, addressing most infrastructure concerns of typical applications. It also goes places other frameworks dont. An open source project since February 2. Fullmetal Alchemist Brotherhood Torrent 720P. Spring has a long heritage. The open source project started from infrastructure code published with my book, Expert One on One J2. Spring Framework 3. Jar Files Not LoadingEE Design and Development, in late 2. Expert One on One J2. EE laid out the basic architectural thinking behind Spring. However, the architectural concepts go back to early 2. Since January 2. 00. Spring has been hosted on Source. Forge. There are now 2. Spring development and support. The flourishing open source community has helped it evolve into far more than could have been achieved by any individual. Architectural benefits of Spring. Before we get down to specifics, lets look at some of the benefits Spring can bring to a project Spring can effectively organize your middle tier objects, whether or not you choose to use EJB. Spring takes care of plumbing that would be left up to you if you use only Struts or other frameworks geared to particular J2. EE APIs. And while it is perhaps most valuable in the middle tier, Springs configuration management services can be used in any architectural layer, in whatever runtime environment.

In my experience, this is a major problem, reducing testability and object orientation. Spring can eliminate the need to use a variety of custom properties file formats, by handling configuration in a consistent way throughout applications and projects. Ever wondered what magic property keys or system properties a particular class looks for, and had to read the Javadoc or even source code With Spring you simply look at the classs Java. Bean properties or constructor arguments. The use of Inversion of Control and Dependency Injection discussed below helps achieve this simplification. Spring can facilitate good programming practice by reducing the cost of programming to interfaces, rather than classes, almost to zero. Spring is designed so that applications built with it depend on as few of its APIs as possible. Click on the classpath tab 4. Include the Spring jar file here, it may also required common log jar due to Spring dependency. Tutorial for how to work with properties files and property values in Spring. Most business objects in Spring applications have no dependency on Spring. Applications built using Spring are very easy to unit test. Spring can make the use of EJB an implementation choice, rather than the determinant of application architecture. You can choose to implement business interfaces as POJOs or local EJBs without affecting calling code. Spring helps you solve many problems without using EJB. Spring can provide an alternative to EJB thats appropriate for many applications. For example, Spring can use AOP to deliver declarative transaction management without using an EJB container even without a JTA implementation, if you only need to work with a single database. Spring provides a consistent framework for data access, whether using JDBC or an OR mapping product such as Top. Link, Hibernate or a JDO implementation. Spring provides a consistent, simple programming model in many areas, making it an ideal architectural glue. You can see this consistency in the Spring approach to JDBC, JMS, Java. Mail, JNDI and many other important APIs. Spring is essentially a technology dedicated to enabling you to build applications using POJOs. This desirable goal requires a sophisticated framework, which conceals much complexity from the developer. Thus Spring really can enable you to implement the simplest possible solution to your problems. And thats worth a lot. What does Spring do Spring provides a lot of functionality, so Ill quickly review each major area in turn. Mission statement. Firstly, lets be clear on Springs scope. Although Spring covers a lot of ground, we have a clear vision as to what it should and shouldnt address. Springs main aim is to make J2. EE easier to use and promote good programming practice. It does this by enabling a POJO based programming model that is applicable in a wide range of environments. Spring does not reinvent the wheel. Thus youll find no logging packages in Spring, no connection pools, no distributed transaction coordinator. All these things are provided by open source projects such as Commons Logging, which we use for all our log output, or Commons DBCP, or by your application server. For the same reason, we dont provide an OR mapping layer. There are good solutions to this problem such as Top. Link, Hibernate and JDO. Spring does aim to make existing technologies easier to use. For example, although we are not in the business of low level transaction coordination, we do provide an abstraction layer over JTA or any other transaction strategy. Spring doesnt directly compete with other open source projects unless we feel we can provide something new. For example, like many developers, we have never been happy with Struts, and felt that there was room for improvement in MVC web frameworks. With Spring MVC adoption growing rapidly, it seems that many agree with us. In some areas, such as its lightweight Io. C container and AOP framework, Spring does have direct competition, but Spring was a pioneer in those areas. Spring benefits from internal consistency. All the developers are singing from the same hymn sheet, the fundamental ideas remaining faithful to those of Expert One on One J2. EE Design and Development. And weve been able to use some central concepts, such as Inversion of Control, across multiple areas. Spring is portable between application servers. Of course ensuring portability is always a challenge, but we avoid anything platform specific or non standard in the developers view, and support users on Web. Logic, Tomcat, Resin, JBoss, Jetty, Geronimo, Web. Sphere and other application servers. Build a Java Application with Eclipse, Spring, and Oracle Web. Logic Server. Build a Java Application with Eclipse, Spring, and Oracle Web. Logic Server. Oracle Enterprise Pack for Eclipse makes developing applications for the Spring Framework andor for Oracle Web. Logic Server easier. Heres how. by Dustin Marx. Published February 2. Oracle Enterprise Pack for Eclipse OEPE is a set of certified plug ins designed for easy integration with the core Eclipse IDE to provide additional support for developing and deploying enterprise Java applications with the Spring Framework and Oracle Web. Logic Server. In this article, Ill offer an overview of this support. Installing Oracle Enterprise Pack for Eclipse. Oracle Enterprise Pack for Eclipse 1. Eclipse installation via the normal plug in mechanisms. An especially convenient alternative is to download a complete version of Eclipse that comes with OEPE already configured. Once the plug ins have been installed, or the complete version of Eclipse with OEPE already configured has been installed, the availability of these plug ins can be verified by selecting the About Eclipse Platform option from the Help menu. Each of the five square buttons with rounded corners represents an installed plug in feature. The two features of particular interest for this article are the two features with rightmost buttons. The Spring IDE feature button is the furthest right feature button and the button to its left represents the OEPE plug ins. Oracle Enterprise Pack for Eclipse with the Spring Framework. The Spring Framework has become a widely used framework for generation of enterprise Java applications because of the many advantages that it offers. However, there are some aspects of working with the Spring Framework that can be improved through the use of the Spring IDE plug in that is included with  Oracle Enterprise Pack for Eclipse. One of the challenges that developers new to the Spring Framework encounter as they learn about the framework is understanding and working with the XML based Spring configuration files. The Spring IDE functionality included with OEPE provides several features that make working with Spring XML more intuitive. These features include a Design view of Spring XML configuration files, Spring element and attribute completion, and detection and notification of any non compliant entries in the Spring context files. With OEPE, you can create a new Eclipse project as a Spring project. The following two images show how to select a Spring project from the New Project Wizard and how to add specific details on the Spring project when creating it. The wide range of capabilities offered by Spring Framework mean that there are many choices for Spring configuration. It can be difficult to learn and remember how various XML elements, attributes, and namespaces are related in a Spring configuration file. The next image shows how to select the wizard for creating a new Spring definition bean. Once the wizard for a Spring Bean Definition is selected, two steps in the creation wizard allow the name of the Spring context file to be specified and allow the applicable Spring Framework XSD based schemas to be selected. These two steps are shown in the next two images. The image above shows the many XSD namespaces that Spring supports. The namespace that is nearly always useful in Spring context files for declaring the Spring beans the beans namespace is pre selected as indicated in this screen snapshot. The context, util, and p namespaces are also commonly used in Spring applications. Assuming that those are selected and that the other settings shown in the previous screen snapshots are used, the generated Spring context file looks like that shown in the next screen snapshot of the Source tab in Eclipse. Using the Spring Bean Definition wizard allows the Spring context configuration file to be generated correctly and without mistyping. As the preceding screen snapshot demonstrates, the namespaces selected in the wizard are included and the appropriate schema. Locations are provided. The preceding image indicates that the Spring IDE provides a Design tab. This tab allows one to see a Spring XML configuration file as a series of two column rows rather than as raw XML. A particularly useful feature of this Design view is the ability to select applicable attributes, child elements, and other portions of the Spring configuration file from a list of valid possibilities. The next image demonstrates the Spring IDE displaying the available child elements for the Spring configuration root beans element. Geocontrol2 Pc Serial Key. The choices are listed by right clicking on the elements name in the Design view. It is useful to be offered the possible child elements of the beans element. Without this functionality, one must remember or discover what possible child elements will work and must be sure not to mistype those entries. The preceding image also shows an option to add attributes as well. Adding attributes to the Spring configuration element with this mechanism offers the same advantages as adding child elements with this approach. There may be times when it is more convenient to edit Spring configuration files directly in the XML source than in the Design view. In such cases, another advantage of the Spring IDE is the auto completion of Spring context elements and attributes. This auto completion offers the same advantages as the Design view in terms of only presenting viable options. The next screen snapshot demonstrates the suggested child elements offered when I started to type a new element with the opening lt. Several valid choices are offered and the currently selected option, the bean element, has its documentation from the defining XML Schema displayed to help the developer decide if that is the appropriate choice. The inclusion of Springs XSD documentation means that a developer can stay focused on the IDE and not need to move back and forth between the IDE and the relevant XML Schema file. With the drop down selections offered by the Design view and the auto completion drop down selections offered in the Source view, it is much easier to generate a correct Spring context file. However, the benefits the Spring IDE provides for improving the configuration experience do not stop here. When an unrecognized value is specified in a Spring configuration file, the improper syntax is highlighted in red to mark improper syntax in Java code. The next screen snapshot demonstrates the indication that the bean child element was misspelled been. The Spring support provided with OEPE includes support for Spring 2. For example, one of the namespaces that can be selected for inclusion with the Spring Bean Definition wizard is the JMS namespace that was first available in Spring 2. The next screen snapshot shows that the 2. JMS inclusion.   Other namespaces have 2. Many of the Spring IDE features covered so far are largely possible due to the XML Schema Definitions XSDs that constrain the available elements and attributes and their relationships with one another. In the next screen snapshot, the Spring IDE reports two errors and one warning associated with my Spring context file. Validation of the Spring configuration file occurs during a Save. The first error reports that there is No setter found for the property another in class dustin.
