Yup, you need to explicitly define the parent -- otherwise it's null.
Hence the "couldn't load javax.servlet.http.HttpServlet" error -- DefaultDomain is not the parent as we would expect.
Do you think we should by default have DefaultDomain as a parent, if not explicitly defined?
Yeah that makes sense. But strange that it happens even when I specify parent domain via jboss-classloading.xml. Perhaps jboss-classloading-domain.xml overrides that.
Yes I think DefaultDomain as parent by default (like elsewhere) would be acceptable here.
And by the way, how one specifies parent in jboss-classloading-domain.xml? I didn't study the related source. Is there any attribute like 'parent' or so?
