svn commit: r947031 - in /tuscany/sca-java-2.x/contrib/modules/section10/src:
main/java/org/apache/tuscany/sca/something/impl/
test/java/org/apache/tuscany/sca/something/
Author: antelder
Date: Fri May 21 14:49:55 2010
New Revision: 947031
URL: http://svn.apache.org/viewvc?rev=947031&view=rev
Log:
Update for Section10 interface updates and start to try to get it to work more as the spec describes so without nodes and to have installed contributions and deploying/undeploying composites. (The tests getService methods no longer work as the scaclient factory impl expects Nodes to have been created)
