Correct. You can do the following.

To build the branch:
cd branches/sca-java-integration
mvn

Then cd branches/sca-java-integration/samples/sca/calculator
mvn dependency:copy-dependencies <-- this is temporary until we get a 
good Tuscany distribution, it copies all the required jars to a single 
./target/dependencies folder so that you don't have to point to them in 
your Maven repos.
java -Djava.ext.dirs=target/dependency -jar 
target/tuscany-sample-calculator-0.1-integration-incubating-SNAPSHOT.jar
You should see:
3 + 2=5.0
3 - 2=1.0
3 * 2=6.0
3 / 2=1.5

Cool, if others are interested here are the complete steps for an 
Eclipse user:
cd branches/sca-java-integration
mvn -Peclipse eclipse:eclipse
In your Eclipse Workbench configure an M2_REPO variable pointing to your 
Maven2 repository directory
 From the Eclipse Workbench menu bar select File / Import / Existing 
Projects into Workspace
Click Next
Select root directory: .../branches/sca-java-integration
Projects for all the modules in the branch will be selected, press Finish
You now have an Eclipse Workspace loaded with all the source code in the 
branch, including the samples.

Then it's very simple, you run the calculator sample like any other 
normal Java application.
 From the Package Explorer view, right click on Project 
tuscany-sample-calculator - class  src/main/java/calculator.CalculatorClient
Select Run As / Java Application
You should see:
3 + 2=5.0
3 - 2=1.0
3 * 2=6.0
3 / 2=1.5

To run the calculator test case:
 From the Package Explorer view, right click on Project 
tuscany-sample-calculator - class  src/test/java/calculator.CalculatorClient
Select Run As / JUnit Test (or Debug As / JUnit Test)

I'm usually following the steps I described above to debug in Eclipse.
