Leo,
Thanks. I'll take a look at these. I tried getting the
latest version of Loom. But it didn't work when I tried to
load James. Missing jar. I will play with it a bit more, I
imagine it is a jar version problem. The instrumentation
code in Loom is pretty old. It is using the old API before I
restructured it last year.
Do you know what James is planning to do in the future?
Being built on top of a frozen code base doesn't seem optimal
in the long term
Never tried to use loom, what is the missing jar?
I've just committed to james an upgrade to the latest avalon-framework,
cornerstone and excalibur libs.
I also rebuilt/updated the bundled phoenix to use the latest
avalon-framework libs.
It seems to work fine.
We probably release a 2.3.0 or 3.0 still built over avalon. We will probably
move to OSGi or a different container later.
Here is the error that gets thrown when Loom attempts to load the james app:
