detection, user-defined probes, and code coverage
► Crystal Reports for developing visual data reports
► Component test automation tools to automate creating tests and building and
managing test cases
8.3.3 WebSphere rapid deployment
WebSphere rapid deployment is a set of tools and capabilities (non-graphical
command line interface) included in the WebSphere Application Server V7.0
packaging and also used by the development tools. These features allow for the
deployment of applications with minimum effort on the part of the developer or
administrator. The rapid deployment model has the following three basic
features:
► Annotation-based programming
► Deployment automation
► Enhanced EAR file
Annotation-based programming enables you to annotate the EJB, servlet, or
Web service module code with special Javadoc syntax annotations. When the
source of the module is saved, the directives in these annotations are parsed,
and the rapid deployment tools use the directives to update deployment
descriptors. The developer can then concentrate on the Java source code rather
than metadata files.
Deployment automation is where applications installation packages are dropped
into a hot directory under an application server and the application is installed
automatically. Any installation parameters that have not been specified by the
installation package’s deployment descriptors have default values that are
applied by the automated deployment process.
Rapid deployment allows for a free-form deployment operation. In this mode, it is
possible to drop source code or compiled classes for servlets, EJBs, JSPs,
images, and so on into the hot directory without strict J2EE packaging. Rapid
deployment then compiles the classes, adds deployment descriptors, and
generates an EAR file that is automatically deployed on a running server.
An enhanced EAR file enables the enterprise archive package to include
information about resources and properties, such as data sources, which is
required by an application. When deployed on a server, the resources are
automatically created on the server.
