Protege is an ontology development tool. I'm interested in using abcl to develop plugins and TIm Redmond was kind enough to have a stab at doing a first pass integration, but ran into trouble. I wonder if his report makes rings a bell?
Surely the function/class loading code has changed quite a lot since 0.18.1, so I'd advise you to try with abcl from trunk (or wait till 0.19 is released). Maybe the problem won't go away, but it's worth trying - at least we'll get a stack trace that's more meaningful wrt. the current state of affairs.
I included the error on trunk below. The url returned by the class loader has the wrong format. For some reason this url is being parsed in the Pathname class and it gets into trouble. I was thinking that it might be possible for me to make a minimal change to the code somehow to fix this but I have not yet figured out exactly how to make this change.
Pathname represents a path to a file or, since recently, an entry in a Jar file, but it's not able to represent an arbitrary URL.
I know little about OSGi, but probably it requires some special handling if one wants to explicitly load resources like ABCL does.
As an attempt which I really doubt will work, you can try this: since what is failing is getLispHome() in class Site, and that can also use the "abcl.home" system property, you could try to set that property to "jar:file:/whatever/abcl.jar!/org/armedbear/lisp/" before loading ABCL and cross your fingers. You'll probably get past the current failing point but some other things will probably fail. Even if it works, it's not a good solution at all; still, it might serve as a temporary hack until we figure out how to behave in a OSGi context.
A bit better is to not hardcode the location: (defvar *abcl-jar* (make-pathname :device (pathname-device (java::jcall "toString" (java::jcall "getResource" (java::jclass "org.armedbear.lisp.Main") "/org/armedbear/lisp/Main.class"))))) Can we put that in system.lisp? -Alan

There is something of a difficulty in using this library. It is doing some funky stuff with urls and class loaders and this doesn't work with Protege. Probably could be made to work by making some changes to the abcl sources. In particular it seems to detect that it is loading through the class loader if the prefix begins with jar which is not a correct assumption in general.
But here is a start if you want to debug a bit more.
