Power users can employ these capabilities to create many different layouts for their projects. We will start with a short description of this advanced project capability, and then give examples demonstrating its use. This nature indicates that these projects have a structural model for the modules and will support WTP tools. Technically speaking, an Eclipse project that has the Module Core Nature is a Web project. We'll use the term Web project in this book. For that reason, WTP developers sometimes also refer to these projects as flexible projects. This mapping gives you flexibility to create projects in ways that you could not do before. Publishers and WTP tools use the structural model to create J2EE artifacts. Each WTP Web project has a structural model that is used to describe how developers lay out the resources. In WTP, the developer's view of a project is captured by a model that maps the contents of the project to the runtime view. Mimicking the structures defined in the specification creates valid J2EE applications, but this is not always suitable for all development projects. The developer's view is most often modeled using the J2EE specification. The runtime view is defined by the J2EE specification. A key requirement for Web projects was to enable the separation of the two fundamental view points to help manage resources in a project, for example, the developer view and the runtime view. When the WTP project was started, the development team had long discussions on how to extend the basic Java projects to handle different styles of custom projects. Unit and integration tests are part of the development for each module. Test objectives and responsibilities are determined based on the modules. Testing: Test plans, test cases, and execution of the tests must be regular and continuous parts of the development process.The configuration and version of components that make an application are very important to the release process. The organization of these components determines the units that are used to control the changes in the scope of the project. It is important to track the changes to these components using a version control system. Change Control, Configuration and Release Management: Software can be viewed in terms of components that are assembled and configured to form an application.The structure of the project is a significant factor in determining the productivity of the team and the management of the overall software engineering process. A team can be one person or it can have groups of developers. Team Organization: Team organization determines who will do what in the project.The J2EE specification describes a structure for these deliverables. An application may group many Web applications and EJBs together. Some projects are simple Web applications while others involve multiple modules and components. However, it will be better to divide the projects if the Web and EJB containers are on different servers. You may use a single EAR project if all the containers run on the same application server. Architecture also influences the design of deliverables. For example, in a J2EE development project, deliverables are the standard modules such as Web application archives (WARs), EJB component archives (JARs), Enterprise application archives (EARs), and so forth. Project Deliverables: These are the concrete outputs of the development activities.Here are some development considerations that can determine the organization of a project: Sometimes you need to do more with a Web project you can use it to improve your development process, organize your code, and share your work with other team members. The default project types and layouts cover many of the common application and development needs. Eclipse Web Tools Platform: Developing Java Web Applications ![]()
