Right, SCA Java imports will only be effective in environments using a
different classloader per SCA contribution, which we have not
encountered yet. I'd suggest to revisit this when we encounter such an
environment. For now adding support for Java import/export only helps
validate the import/export extensibility mechanism.
How about we create such an environment? We seemed to be getting lots of
new
function added these days - for things like starting and stopping,
incremental updates, this import/export stuff, etc - but nothing that
actually properly uses the function, and then issues like the above
mentioned class loader problem meaning its actually not at all easy to use
the function when you do try to. I don't think thats so good for the
project
as it makes it hard to understand why things a getting so complicated, so
wouldn't it be better to have something 'real' that exercises that code?
How
about we create an environment that properly demonstrates using multiple
contributions and all the code and function we're adding around that?
I think we need to have a good balance here. Writing a new Tuscany server is
exciting. For those who already run their applications on existing host
environment such as Tomcat and Geronimo, maybe it's more desirable to have
Tuscany to be well integrated/embedded. I agree with you that we need to
have something real that exercises the new features. IMHO, Tuscany/Geronimo
integration will be a good testbed.
