Sebastien,
Sorry, ignore my previous note (the one below). Even with assets not in the
classpath, I can run launch.LaunchCloud as long as the assets contribution
is added first. The code in svn does:
currencyNode.addContribution("http://cloud";, cloudContribution);
catalogsNode.addContribution("http://assets";, assetsContribution);
assets should be aded to currencyNode before cloud (at least with the
current code). With that change, it runs without throwing any exceptions.
With the latest code and after fixing the addContribution calls
LaunchCloud now works for me too. Thanks.
However, after starting LaunchCloud, starting LaunchStore throws the
exception below, as o.a.t.implementation.data.api.collection.Collection
is required by services.ShoppingCart but not on the contribution path.
Adding implementation-data-api.jar and derby.jar as contributions (as I
did in SVN r608288) is not sufficient as these JARs don't have an
sca-contribution.xml exporting their classes.
Summary: classes that depend on existing JARs (likely to happen in many
component implementation classes) cannot be loaded from SCA
contributions, as the existing JARs are not properly handled by the
contribution processor.
I'll try to fix the contribution processor, the contribution ClassLoader
and the import/export machinery later this week.
P.S. Simon, I don't think that you need to wait for the fix for the 1.1
release.
Here's the exception:
