In SCA, applications are packaged in one or more contributions. Contributions can be a variety of formats. Fabric3 supports the following formats and can be extended to support others:
- JAR archives
- OSGi bundles
- WAR archives
- ZIP archives
- XML documents
JAR contributions
Most SCA applications will be packaged as one or more JARs. In addition to including application classes and artifacts, a JAR-based contribution may contain an sca-contribution.xml manifest file in the META-INF directory. The The manifest file contains contribution metadata, including a list of deployable composites. Deployable composites are those composites that are contained in the contribution which are to be deployed to a domain. A contribution may contain other composites but if they are not marked as deployable, they may not be directly included in the domain (i.e. they may only be used by a deployable composite). An example sca-contribution.xml file is shown below:
