More James...

I changed the class loader to use only one dynamic assembly and tried to run James again. It still doesn't run:

Phoenix 4.0a4

Application file://C:/james/apps/james.sar uses a deprecated packaging format.
There was an uncaught exception:

Please check the configuration files and restart Phoenix.

Shutting down Phoenix.

(I editted the stack trace a little so that it doesn't mess up the formatting of the page too much).

I have no idea what this means and I don't feel like debugging this. May be I'll revisit James in a while when I've implemented more stuff and have better debugging support.

Could be the Class or ClassLoader getResource() methods that are failing to be found?

Possibly. I know next to nothing about resources, but I had hoped that Classpath's URLClassLoader would know how to read resources from jars/zips.

GNU Classpath should handle loading resources from jars just fine.
And if it doesn't then that is my bug because I wrote URLClassLoader :)
If you have or can point me to some simple instructions on what you did, which version, etc.
then I can try and see what another GNU Classpath based VM gives.

Many thanks Mark. I've sent you an e-mail.

OK, analysed the problem. There is a thinko in URLClassLoader from GNU Classpath.
James feeds .bar files to an URLClassLoader that not correctly recognizes them
as actual jar or zip files. Will be fixed shortly while I also integrate some
patches the Intel Orp developers send that speed up URLClassLoader a lot.

I apologize for the lameness of this, but the comment spam was driving me nuts. In order to be able to post a comment, you need to answer a simple question. Hopefully this question is easy enough not to annoy serious commenters, but hard enough to keep the spammers away.

Anti-Spam Question: What method on java.lang.System returns an object's original hashcode (i.e. the one that would be returned by java.lang.Object.hashCode() if it wasn't overridden)? (case is significant)
