Hi Mayank
I believe it looks on the current classpath. As we run our tests through
maven our resource directory (for samples this is main/resources) is copied,
by maven, to the classpath (target/classes) and hence is available for the
runtime to pickup. It maybe in you case that resources in the source
directory are not available on the classpath.
The domain also has to be told which composites are expected to be deployed.
You'll note that in a lot of our samples this is done using a single
parameter to the SCAomain. For exampl, if you look in the CalculatorTestCase
that comes with the Calculator sample [1] you can see the line that starts
the domain
scaDomain = SCADomain.newInstance("Calculator.composite");
There are other ways of specifying which composites are going to be
deployed. For example, the FAQ [2] talks about the sca-contribution.xml file
and the sca-deployables directory.
As an aside we are just, at this moment, tidying up our SCADomain support.
Do you think its useful to provide a constructor like this that takes no
parameters and by default tries to load the contribution from the classpath?
I've always felt that appears a bit mysterious/magic and would rather have
contribution be an explicit step. Would welcome your views.
