Overview

There are not huge differences in the SCA that Tuscany 1.x implements (OSOA v1.0) and the SCA that Tuscany 2.x implements (OASIS v1.1). However there are detailed differences that you need to be aware of in SCA and in the Tuscany runtime in order to get your 1.x application to work in 2.x.

Converting composites and other SCA XML artifacts

Namespaces

The SCA and Tuscany namespaces may be used in the following files

*.composite
sca-contribution.xml
defintions.xml

Each occurrence needs changing for 2.x

1.x Namespace		2.x Namespace
http://www.osoa.org/xmlns/sca/1.0	===>	http://docs.oasis-open.org/ns/opencsa/sca/200912
http://tuscany.apache.org/xmlns/sca/1.0	===>	http://tuscany.apache.org/xmlns/sca/1.1

Converting dependencies

You need to re-configure the project pom.xml

1.x Dependencies		2.x Dependencies
<dependency> <groupId>org.apache.tuscany.sca</groupId> <artifactId>tuscany-assembly</artifactId> <version>1.6-SNAPSHOT</version> </dependency>	===>	<dependency> <groupId>org.apache.tuscany.sca</groupId> <artifactId>tuscany-assembly</artifactId> <version>2.0-SNAPSHOT</version> </dependency>

TODO - need to note what the final Tuscany feature grouping solution is for 2.x
