Hi, some comments in line
There has been many commits and good progress the last few days, so I
spent a little bit of time checking the status of the trunk.
Here's a summary of what I found:
- The code cleanup is almost complete, I think there's a little bit work
left to refactor one last .spi.

I'm working steadily through the samples...

I've seen much discussion on the list re. a webapp solution. There is now a

Is this a work in progress?

I tried running the calculator-web sample this morning and got an NPE in
calc.jsp. I'm guessing but it looks like it can't find the domain instance,

So what is it using doamin uri for. Looking at the sca-contribution.xml in
the assembly spec there doesn't seem to be any information that I would
equate with the uri of a domain. Then again I don't know what Tuscany is

I've checked in changes to allows the provided jar to be run (and built).
Outstanding is the issue of including classes from

My suggestion was much simpler, i.e., that we could keep the client
code out of the sample extension jar and include a .class file for the
client code for these 3 samples in the binary distro. This is similar
to what real users will do when developing extensions.
Making this happen is
ok - well we can do that and it's pretty much zero change as that is where
we are at the moment, i.e. you have to build the sample before you run it. I
don't think providing ant scripts is a problem as we could make the "run"
target depend on the "compile" target for the three extension samples.
