Most of our samples simply include .composite files on the classpath, i.e. under the target/classes dir as generated by mvn. The Tuscany contribution service will look here and load any .composite files that it finds. There are other alternatives
sca-contributions
META-INF/sca-contribution.xml
If you have a contribution in a directory say.
/my/contribution/dir
Then all components in composites under this directory will be located by the contribution service and any composites that are named in the sca-contribution.xml file will be automatically be included in the deployable list maintained by the contribution, for example
/my/contribution/dir/META-INF/sca-contribution.xml
/my/contribution/dir/mycomposite.composite
Where sca-contribution.xml is
<contribution xmlns="http://www.osoa.org/xmlns/sca/1.0"
targetNamespace="http://mycomposite"
xmlns:management="http://mycomposite">
<deployable composite="mycomposite:MyComposite"/>
</contribution>
META-INF/sca-deployables/
If you have a contribution in a directory say.
/my/contribution/dir
Then all components in composites under this directory will be located by the contribution service and any composites under the directory /META-INF/sca-deployables/ will be automatically be included in the deployable list maintained by the contribution, for example
/my/contribution/dir/META-INF/sca-deployables/mycomposite.composite
