Hi JP
Where is the file "Restaurant.composite" relative to the module that
you are using to develop the test case? Tuscany is trying to find a
contribution by looking for this file on the classpath.
An SCA contribution is a hierarchical set of information such as
composite files, WSDLs, XSDs etc that are required to run your SCA
application. It could be a directory structure, a zip, a jar etc. When
you create the node you have to tell it which contribution to load.
If, for example, you look in the CalculatorTestCase of the 2.x
Calculator sample you see the following...
node = NodeFactory.newInstance().createNode((String)null, new
String[] {"target/classes"}).start();
calculatorService = node.getService(CalculatorService.class,
"CalculatorServiceComponent");
Here we loading the whole of the ./target/classes directory as the
contribution. We do this as this sample is build using Maven and this
is where Maven puts all the compiled Java classes and resources by
default.
Are you able to successfully run the Calculator sample?
Regards
Simon
