Hi Scott,
Thanks for the reply. We are creating a simple testcase as I write.
We are, however, having trouble tracking down the location of the
Java2ClassLoadingCompliance attribute - searches through the JBoss pdf
manual (as of January), JBoss installations, the JBoss site and some of
the DTDs have yielded nothing.
Is 'Java2ClassLoadingCompliance' the exact phrase, and what is it an
attribute of?
Thanks
david
